 dependencies:
   platform_reflection: ^0.1.0
 ```
 
-## Usage
+## Core Components
 
-### Basic Reflection
+### Reflector
 
-Simply mark your class with `@reflectable`:
+Central management class for reflection operations:
 
 ```dart
-import 'package:platform_reflection/reflection.dart';
+class Reflector {
+  // Type registration
+  static void register(Type type);
+  static void registerProperty(Type type, String name, Type propertyType);
+  static void registerMethod(Type type, String name, List<Type> parameterTypes);
+  static void registerConstructor(Type type, String name, {Function? creator});
+  
+  // Metadata access
+  static TypeMetadata? getTypeMetadata(Type type);
+  static Map<String, PropertyMetadata>? getPropertyMetadata(Type type);
+  static Map<String, MethodMetadata>? getMethodMetadata(Type type);
+  
+  // Utility methods
+  static void reset();
+  static bool isReflectable(Type type);
+}
+```
 
+### Scanner
+
+Automatic metadata extraction and analysis:
+
+```dart
+class Scanner {
+  // Scanning operations
+  static void scanType(Type type);
+  static TypeMetadata getTypeMetadata(Type type);
+  
+  // Analysis methods
+  static TypeInfo analyze(Type type);
+  static List<PropertyInfo> analyzeProperties(Type type);
+  static List<MethodInfo> analyzeMethods(Type type);
+}
+```
+
+### RuntimeReflector
+
+Runtime reflection implementation:
+
+```dart
+class RuntimeReflector {
+  // Instance creation
+  InstanceMirror createInstance(Type type, {
+    List<dynamic>? positionalArgs,
+    Map<Symbol, dynamic>? namedArgs,
+    String? constructorName,
+  });
+  
+  // Reflection operations
+  InstanceMirror reflect(Object object);
+  ClassMirror reflectClass(Type type);
+  TypeMirror reflectType(Type type);
+}
+```
+
+## Usage Guide
+
+### Basic Registration
+
+```dart
 @reflectable
 class User {
   String name;
@@ -48,146 +175,334 @@ class User {
   }
 
   String greet(String greeting) {
-    return '$greeting, $name!';
+    return '$greeting $name!';
+  }
+}
+
+// Register class and members
+void registerUser() {
+  Reflector.register(User);
+  
+  // Register properties
+  Reflector.registerProperty(User, 'name', String);
+  Reflector.registerProperty(User, 'age', int);
+  Reflector.registerProperty(User, 'id', String, isWritable: false);
+  
+  // Register methods
+  Reflector.registerMethod(
+    User,

+    creator: (String name, int age, {required String id}) => 
+        User(name, age, id: id),
+  );
+}
+```
+
+### Instance Manipulation
+
+```dart
+void manipulateInstance() {
+  final reflector = RuntimeReflector.instance;
+  
+  // Create instance
+  final user = reflector.createInstance(
+    User,
+    positionalArgs: ['John', 30],
+    namedArgs: {const Symbol('id'): '123'},
+  ) as User;
+  
+  // Get mirror
+  final mirror = reflector.reflect(user);
+  
+  // Property access
+  final name = mirror.getField(const Symbol('name')).reflectee as String;
+  final age = mirror.getField(const Symbol('age')).reflectee as int;
+  
+  // Property modification
+  mirror.setField(const Symbol('name'), 'Jane');
+  mirror.setField(const Symbol('age'), 31);
+  
+  // Method invocation
+  mirror.invoke(const Symbol('birthday'), []);
+  final greeting = mirror.invoke(
+    const Symbol('greet'),
+    ['Hello'],
+  ).reflectee as String;
+}
+```
+
+### Type Introspection
+
+```dart
+void inspectType() {
+  final metadata = Reflector.getTypeMetadata(User);
+  
+  // Property inspection
+  for (var property in metadata.properties.values) {
+    print('Property: ${property.name}');
+    print('  Type: ${property.type}');
+    print('  Writable: ${property.isWritable}');
+    print('  Static: ${property.isStatic}');
+  }
+  
+  // Method inspection
+  for (var method in metadata.methods.values) {
+    print('Method: ${method.name}');
+    print('  Return type: ${method.returnType}');
+    print('  Parameters:');
+    for (var param in method.parameters) {
+      print('    ${param.name}: ${param.type}');
+      print('    Required: ${param.isRequired}');
+      print('    Named: ${param.isNamed}');
+    }
+  }
+  
+  // Constructor inspection
+  for (var ctor in metadata.constructors) {
+    print('Constructor: ${ctor.name}');
+    print('  Parameters:');
+    for (var param in ctor.parameters) {
+      print('    ${param.name}: ${param.type}');
+      print('    Required: ${param.isRequired}');
+      print('    Named: ${param.isNamed}');
+    }
   }
 }
 ```
 
-Then use reflection directly:
+### Scanner Usage
 
 ```dart
-// Get the reflector instance
-final reflector = RuntimeReflector.instance;
-
-// Create instance using reflection
-final user = reflector.createInstance(
-  User,
-  positionalArgs: ['John', 30],
-  namedArgs: {'id': '123'},
-) as User;
-
-// Get instance mirror
-final mirror = reflector.reflect(user);
-
-// Access properties
-print(mirror.getField(const Symbol('name')).reflectee); // John
-print(mirror.getField(const Symbol('age')).reflectee); // 30
-
-// Modify properties
-mirror.setField(const Symbol('name'), 'Jane');
-mirror.setField(const Symbol('age'), 25);
-
-// Invoke methods
-mirror.invoke(const Symbol('birthday'), []);
-final greeting = mirror.invoke(const Symbol('greet'), ['Hello']).reflectee;
-print(greeting); // Hello, Jane!
-```
-
-### Type Information
-
-```dart
-// Get mirror system
-final mirrors = reflector.currentMirrorSystem;
-
-// Get type mirror
-final typeMirror = mirrors.reflectType(User);
-
-// Access type information
-print(typeMirror.name); // User
-print(typeMirror.properties); // {name: PropertyMetadata(...), age: PropertyMetadata(...)}
-print(typeMirror.methods); // {birthday: MethodMetadata(...), greet: MethodMetadata(...)}
-
-// Check type relationships
-if (typeMirror.isSubtypeOf(otherType)) {
-  print('User is a subtype');
-}
-
-// Get declarations
-final declarations = typeMirror.declarations;
-for (var member in declarations.values) {
-  if (member is MethodMirror) {
-    print('Method: ${member.simpleName}');
-  } else if (member is VariableMirror) {
-    print('Variable: ${member.simpleName}');
+void useScannerFeatures() {
+  // Scan type
+  Scanner.scanType(User);
+  
+  // Get scanned metadata
+  final metadata = Scanner.getTypeMetadata(User);
+  
+  // Analyze type structure
+  final typeInfo = Scanner.analyze(User);
+  
+  // Property analysis
+  final properties = typeInfo.properties;
+  for (var prop in properties) {
+    print('Property: ${prop.name}');
+    print('  Type: ${prop.type}');
+    print('  Final: ${prop.isFinal}');
   }
-}
-
-// Access special types
-print(mirrors.dynamicType.name); // dynamic
-print(mirrors.voidType.name); // void
-print(mirrors.neverType.name); // Never
-```
-
-### Library Reflection
-
-```dart
-// Get a library
-final library = mirrors.findLibrary(const Symbol('package:myapp/src/models.dart'));
-
-// Access library members
-final declarations = library.declarations;
-for (var decl in declarations.values) {
-  print('Declaration: ${decl.simpleName}');
-}
-
-// Check imports
-for (var dep in library.libraryDependencies) {
-  if (dep.isImport) {
-    print('Imports: ${dep.targetLibrary?.uri}');
+  
+  // Method analysis
+  final methods = typeInfo.methods;
+  for (var method in methods) {
+    print('Method: ${method.name}');
+    print('  Return type: ${method.returnType}');
+    print('  Static: ${method.isStatic}');
+    print('  Parameters: ${method.parameters}');
   }
 }
 ```
 
-### Isolate Reflection
+## Advanced Usage
+
+### Generic Type Handling
 
 ```dart
-// Get current isolate
-final currentIsolate = mirrors.isolate;
-print('Current isolate: ${currentIsolate.debugName}');
+@reflectable
+class Container<T> {
+  T value;
+  Container(this.value);
+}
 
-// Reflect on another isolate
-final isolate = await Isolate.spawn(workerFunction, message);
-final isolateMirror = reflector.reflectIsolate(isolate, 'worker');
-
-// Control isolate
-await isolateMirror.pause();
-await isolateMirror.resume();
-await isolateMirror.kill();
-```
-
-## Error Handling
-
-The package provides specific exceptions for different error cases:
-
-- `NotReflectableException`: Thrown when attempting to reflect on a non-reflectable type
-- `ReflectionException`: Base class for reflection-related errors
-- `InvalidArgumentsException`: Thrown when providing invalid arguments to a method or constructor
-- `MemberNotFoundException`: Thrown when a property or method is not found
-
-```dart
-try {
-  reflect(NonReflectableClass());
-} catch (e) {
-  print(e); // NotReflectableException: Type NonReflectableClass is not reflectable
+void handleGenericType() {
+  Reflector.register(Container);
+  
+  // Register with specific type
+  final stringContainer = reflector.createInstance(
+    Container,
+    positionalArgs: ['Hello'],
+  ) as Container<String>;
+  
+  final mirror = reflector.reflect(stringContainer);
+  final value = mirror.getField(const Symbol('value')).reflectee as String;
 }
 ```
 
-## Design Philosophy
+### Error Handling
 
-This package provides a reflection API that closely mirrors the design of `dart:mirrors` while being:
+```dart
+void demonstrateErrorHandling() {
+  try {
+    // Attempt to reflect unregistered type
+    reflector.reflect(UnregisteredClass());
+  } on NotReflectableException catch (e) {
+    print('Type not registered: $e');
+  }
+  
+  try {
+    // Attempt to access non-existent member
+    final mirror = reflector.reflect(user);
+    mirror.getField(const Symbol('nonexistent'));
+  } on MemberNotFoundException catch (e) {
+    print('Member not found: $e');
+  }
+  
+  try {
+    // Attempt invalid method invocation
+    final mirror = reflector.reflect(user);
+    mirror.invoke(const Symbol('greet'), [42]); // Wrong argument type
+  } on InvalidArgumentsException catch (e) {
+    print('Invalid arguments: $e');
+  }
+}
+```
 
-- Platform independent
-- Lightweight
-- Type-safe
-- Performant
-- Easy to use
+## Performance Considerations
 
-The implementation uses pure Dart runtime scanning to provide reflection capabilities across all platforms without requiring code generation or manual registration.
+### Registration Impact
+
+- Explicit registration adds startup cost
+- Improved runtime performance
+- Reduced memory usage
+- Controlled reflection surface
+
+### Optimization Techniques
+
+1. **Lazy Loading**
+   ```dart
+   // Only register when needed
+   if (Reflector.getTypeMetadata(User) == null) {
+     registerUser();
+   }
+   ```
+
+2. **Metadata Caching**
+   ```dart
+   // Cache metadata access
+   final metadata = Reflector.getTypeMetadata(User);
+   final properties = metadata.properties;
+   final methods = metadata.methods;
+   ```
+
+3. **Instance Reuse**
+   ```dart
+   // Reuse instance mirrors
+   final mirror = reflector.reflect(user);
+   // Store mirror for repeated use
+   ```
+
+### Memory Management
+
+- Metadata storage optimization
+- Instance mirror lifecycle management
+- Cache invalidation strategies
+
+## Migration Guide
+
+### From dart:mirrors
+
+```dart
+// Old dart:mirrors code
+import 'dart:mirrors';
+
+final mirror = reflect(instance);
+final value = mirror.getField(#propertyName).reflectee;
+
+// New platform_reflection code
+import 'package:platform_reflection/reflection.dart';
+
+final mirror = reflector.reflect(instance);
+final value = mirror.getField(const Symbol('propertyName')).reflectee;
+```
+
+### Registration Requirements
+
+```dart
+// Add registration code
+void registerTypes() {
+  Reflector.register(MyClass);
+  Reflector.registerProperty(MyClass, 'property', String);
+  Reflector.registerMethod(MyClass, 'method', [int]);
+}
+```
+

+## Implementation Differences
+
+### Registration System
+
+```dart
+// dart:mirrors
+// No registration needed
+@reflectable
+class MyClass {}
+
+// Platform Reflection
+@reflectable
+class MyClass {}
+
+// Requires explicit registration
+Reflector.register(MyClass);
+Reflector.registerProperty(MyClass, 'prop', String);
+Reflector.registerMethod(MyClass, 'method', [int]);
+```
+
+### Library Access
+
+```dart
+// dart:mirrors
+final lib = MirrorSystem.findLibrary('my_lib');
+
+// Platform Reflection
+final lib = LibraryMirrorImpl.withDeclarations(
+  name: 'my_lib',
+  uri: Uri.parse('package:my_package/my_lib.dart'),
+);
+```
+
+### Isolate Handling
+
+```dart
+// dart:mirrors
+final mirror = reflect(isolate);
+await mirror.invoke(#method, []);
+
+// Platform Reflection
+final mirror = IsolateMirrorImpl.other(isolate, 'name', lib);
+mirror.addErrorListener((error, stack) {
+  // Handle error
+});
+```
+
+### Type System
+
+```dart
+// dart:mirrors
+final type = reflectType(MyClass);
+final isSubtype = type.isSubtypeOf(otherType);
+
+// Platform Reflection
+final type = TypeMetadata(
+  type: MyClass,
+  name: 'MyClass',
+  // ...
+);
+final isSubtype = type.supertype == otherType;
+```
+
+## Performance Characteristics

+
+## Migration Path
+
+### From dart:mirrors
+
+1. Add registration:
+```dart
+// Before
+@reflectable
+class MyClass {}
+
+// After
+@reflectable
+class MyClass {}
+
+void register() {
+  Reflector.register(MyClass);
+  // Register members...
+}
+```
+
+2. Update reflection calls:
+```dart
+// Before
+final mirror = reflect(instance);
+final value = mirror.getField(#prop);
+
+// After
+final mirror = reflector.reflect(instance);
+final value = mirror.getField(const Symbol('prop'));
+```
+
+3. Handle libraries:
+```dart
+// Before
+final lib = MirrorSystem.findLibrary('my_lib');
+
+// After
+final lib = LibraryMirrorImpl.withDeclarations(
+  name: 'my_lib',
+  uri: uri,
+);
+```
+
+## Trade-offs
+
+### Advantages of Platform Reflection
+1. Works everywhere
+2. Better performance
+3. Smaller code size
+4. Better tree shaking
+5. Full isolate support
+6. Production-ready
+
+### Advantages of dart:mirrors
+1. No registration needed
+2. Simpler API
+3. More dynamic capabilities
+4. Better for development tools
+5. More flexible
+
+## Conclusion
+
+Platform Reflection offers a more production-ready alternative to dart:mirrors with:
+- Full cross-platform support
+- Better performance characteristics
+- More controlled reflection surface
+- Full isolate support

+# Platform Reflection Quick Start Guide
+
+This guide covers the most common use cases for Platform Reflection to help you get started quickly.
+
+## Installation
+
+```yaml
+dependencies:
+  platform_reflection: ^0.1.0
+```
+
+## Basic Usage
+
+### 1. Simple Class Reflection
+
+```dart
+import 'package:platform_reflection/reflection.dart';
+
+// 1. Define your class
+@reflectable
+class User {
+  String name;
+  int age;
+  
+  User(this.name, this.age);
+  
+  void birthday() => age++;
+}
+
+// 2. Register for reflection
+void main() {
+  // Register class
+  Reflector.register(User);
+  
+  // Register properties
+  Reflector.registerProperty(User, 'name', String);
+  Reflector.registerProperty(User, 'age', int);
+  
+  // Register methods
+  Reflector.registerMethod(
+    User,
+    'birthday',
+    [],
+    true,
+  );
+  
+  // Register constructor
+  Reflector.registerConstructor(
+    User,
+    '',
+    parameterTypes: [String, int],
+    parameterNames: ['name', 'age'],
+    creator: (String name, int age) => User(name, age),
+  );
+  
+  // Use reflection
+  final user = reflector.createInstance(
+    User,
+    positionalArgs: ['John', 30],
+  ) as User;
+  
+  final mirror = reflector.reflect(user);
+  print(mirror.getField(const Symbol('name')).reflectee); // John
+  mirror.invoke(const Symbol('birthday'), []);
+  print(mirror.getField(const Symbol('age')).reflectee); // 31
+}
+```
+
+### 2. Property Access
+
+```dart
+// Get property value
+final mirror = reflector.reflect(instance);
+final name = mirror.getField(const Symbol('name')).reflectee as String;
+
+// Set property value
+mirror.setField(const Symbol('name'), 'Jane');
+
+// Check if property exists
+final metadata = Reflector.getPropertyMetadata(User);
+if (metadata?.containsKey('name') ?? false) {
+  // Property exists
+}
+```
+
+### 3. Method Invocation
+
+```dart
+// Invoke method without arguments
+mirror.invoke(const Symbol('birthday'), []);
+
+// Invoke method with arguments
+final result = mirror.invoke(
+  const Symbol('greet'),
+  ['Hello'],
+).reflectee as String;
+
+// Invoke method with named arguments
+final result = mirror.invoke(
+  const Symbol('update'),
+  [],
+  {const Symbol('value'): 42},
+).reflectee;
+```
+
+### 4. Constructor Usage
+
+```dart
+// Default constructor
+final instance = reflector.createInstance(
+  User,
+  positionalArgs: ['John', 30],
+) as User;
+
+// Named constructor
+final instance = reflector.createInstance(
+  User,
+  constructorName: 'guest',
+) as User;
+
+// Constructor with named arguments
+final instance = reflector.createInstance(
+  User,
+  positionalArgs: ['John'],
+  namedArgs: {const Symbol('age'): 30},
+) as User;
+```
+
+### 5. Type Information
+
+```dart
+// Get type metadata
+final metadata = Reflector.getTypeMetadata(User);
+
+// Check properties
+for (var property in metadata.properties.values) {
+  print('${property.name}: ${property.type}');
+}
+
+// Check methods
+for (var method in metadata.methods.values) {
+  print('${method.name}(${method.parameterTypes.join(', ')})');
+}
+```
+
+### 6. Error Handling
+
+```dart
+try {
+  // Attempt reflection
+  final mirror = reflector.reflect(instance);
+  mirror.invoke(const Symbol('method'), []);
+} on NotReflectableException catch (e) {
+  print('Type not registered: $e');
+} on MemberNotFoundException catch (e) {
+  print('Member not found: $e');
+} on InvalidArgumentsException catch (e) {
+  print('Invalid arguments: $e');
+} on ReflectionException catch (e) {
+  print('Reflection error: $e');
+}
+```
+
+## Common Patterns
+
+### 1. Registration Helper
+
+```dart
+void registerType<T>(Type type) {
+  Reflector.register(type);
+  
+  final scanner = Scanner();
+  final metadata = scanner.scanType(type);
+  
+  // Register properties
+  for (var property in metadata.properties.values) {
+    Reflector.registerProperty(
+      type,
+      property.name,
+      property.type,
+      isWritable: property.isWritable,
+    );
+  }
+  
+  // Register methods
+  for (var method in metadata.methods.values) {
+    Reflector.registerMethod(
+      type,
+      method.name,
+      method.parameterTypes,
+      method.returnsVoid,
+      parameterNames: method.parameters.map((p) => p.name).toList(),
+      isRequired: method.parameters.map((p) => p.isRequired).toList(),
+    );
+  }
+}
+```
+
+### 2. Property Observer
+
+```dart
+class PropertyObserver {
+  final InstanceMirror mirror;
+  final Symbol propertyName;
+  final void Function(dynamic oldValue, dynamic newValue) onChange;
+  
+  PropertyObserver(this.mirror, this.propertyName, this.onChange);
+  
+  void observe() {
+    var lastValue = mirror.getField(propertyName).reflectee;
+    
+    Timer.periodic(Duration(milliseconds: 100), (_) {
+      final currentValue = mirror.getField(propertyName).reflectee;
+      if (currentValue != lastValue) {
+        onChange(lastValue, currentValue);
+        lastValue = currentValue;
+      }
+    });
+  }
+}
+```
+
+### 3. Method Interceptor
+
+```dart
+class MethodInterceptor {
+  final InstanceMirror mirror;
+  final Symbol methodName;
+  final void Function(List args, Map<Symbol, dynamic> named) beforeInvoke;
+  final void Function(dynamic result) afterInvoke;
+  
+  MethodInterceptor(
+    this.mirror,
+    this.methodName,
+    {this.beforeInvoke = _noOp,
+    this.afterInvoke = _noOp});
+    
+  static void _noOp([dynamic _]) {}
+  
+  dynamic invoke(List args, [Map<Symbol, dynamic>? named]) {
+    beforeInvoke(args, named ?? {});
+    final result = mirror.invoke(methodName, args, named).reflectee;
+    afterInvoke(result);
+    return result;
+  }
+}
+```
+
+## Best Practices
+
+1. **Register Early**
+   ```dart
+   void main() {
+     // Register all types at startup
+     registerType<User>();
+     registerType<Order>();
+     registerType<Product>();
+     
+     // Start application
+     runApp();
+   }
+   ```
+
+2. **Cache Mirrors**
+   ```dart
+   class UserService {
+     final Map<User, InstanceMirror> _mirrors = {};
+     
+     InstanceMirror getMirror(User user) {
+       return _mirrors.putIfAbsent(
+         user,
+         () => reflector.reflect(user),
+       );
+     }
+   }
+   ```
+
+3. **Handle Errors**
+   ```dart
+   T reflectSafely<T>(Function() operation, T defaultValue) {
+     try {
+       return operation() as T;
+     } on ReflectionException catch (e) {
+       print('Reflection failed: $e');
+       return defaultValue;
+     }
+   }
+   ```
+
+4. **Validate Registration**
+   ```dart
+   bool isFullyRegistered(Type type) {
+     final metadata = Reflector.getTypeMetadata(type);
+     if (metadata == null) return false;
+     
+     // Check properties
+     if (metadata.properties.isEmpty) return false;
+     
+     // Check methods
+     if (metadata.methods.isEmpty) return false;
+     
+     // Check constructors
+     if (metadata.constructors.isEmpty) return false;
+     
+     return true;
+   }
+   ```
+
+## Common Issues
+
+1. **Type Not Registered**
+   ```dart
+   // Wrong
+   reflector.reflect(unregisteredInstance);
+   
+   // Right
+   Reflector.register(UnregisteredType);
+   reflector.reflect(instance);
+   ```
+
+2. **Missing Property/Method Registration**
+   ```dart
+   // Wrong
+   Reflector.register(User);
+   
+   // Right
+   Reflector.register(User);
+   Reflector.registerProperty(User, 'name', String);
+   Reflector.registerMethod(User, 'greet', [String]);
+   ```
+
+3. **Wrong Argument Types**
+   ```dart
+   // Wrong
+   mirror.invoke(const Symbol('greet'), [42]);
+   
+   // Right
+   mirror.invoke(const Symbol('greet'), ['Hello']);
+   ```
+
+## Performance Tips
+
+1. **Cache Metadata**
+   ```dart
+   final metadata = Reflector.getTypeMetadata(User);
+   final properties = metadata.properties;
+   final methods = metadata.methods;
+   ```
+
+2. **Reuse Mirrors**
+   ```dart
+   final mirror = reflector.reflect(instance);
+   // Reuse mirror for multiple operations
+   ```
+
+3. **Batch Registration**
+   ```dart
+   void registerAll() {
+     for (var type in types) {
+       registerType(type);
+     }
+   }
+   ```

+# Platform Reflection Technical Specification
+
+## System Architecture
+
+### Core Components
+
+```mermaid
+graph TD
+    A[Reflector] --> B[Scanner]
+    A --> C[RuntimeReflector]
+    B --> D[TypeAnalyzer]
+    C --> E[MirrorSystem]
+    E --> F[Mirrors]

+    F --> I[MethodMirror]
+```
+
+### Component Responsibilities
+
+#### 1. Reflector
+- Central registration point
+- Metadata management
+- Type registration validation
+- Cache management
+
+```dart
+class Reflector {
+  static final Map<Type, TypeMetadata> _typeCache;
+  static final Map<Type, Map<String, PropertyMetadata>> _propertyMetadata;
+  static final Map<Type, Map<String, MethodMetadata>> _methodMetadata;
+  static final Map<Type, List<ConstructorMetadata>> _constructorMetadata;
+}
+```
+
+#### 2. Scanner
+- Type analysis
+- Metadata extraction
+- Registration validation
+- Type relationship analysis
+
+```dart
+class Scanner {
+  static final Map<Type, TypeInfo> _typeInfoCache;
+  
+  static TypeInfo analyze(Type type) {
+    // Analyze class structure
+    // Extract metadata
+    // Build type relationships
+  }
+}
+```
+
+#### 3. RuntimeReflector
+- Instance creation
+- Method invocation
+- Property access
+- Type reflection
+
+```dart
+class RuntimeReflector {
+  InstanceMirror reflect(Object object) {
+    // Create instance mirror
+    // Setup metadata access
+    // Configure invocation handling
+  }
+}
+```
+
+### Metadata System
+
+#### Type Metadata
+```dart
+class TypeMetadata {
+  final Type type;
+  final String name;
+  final Map<String, PropertyMetadata> properties;
+  final Map<String, MethodMetadata> methods;
+  final List<ConstructorMetadata> constructors;
+  final bool isAbstract;
+  final bool isEnum;
+}
+```
+
+#### Method Metadata
+```dart
+class MethodMetadata {
+  final String name;
+  final List<Type> parameterTypes;
+  final List<ParameterMetadata> parameters;
+  final bool returnsVoid;
+  final bool isStatic;
+  final bool isAbstract;
+}
+```
+
+#### Property Metadata
+```dart
+class PropertyMetadata {
+  final String name;
+  final Type type;
+  final bool isReadable;
+  final bool isWritable;
+  final bool isStatic;
+}
+```
+
+## Implementation Details
+
+### Registration Process
+
+1. Type Registration
+```dart
+static void register(Type type) {
+  // Validate type
+  if (_typeCache.containsKey(type)) return;
+  
+  // Create metadata
+  final metadata = TypeMetadata(
+    type: type,
+    name: type.toString(),
+    properties: {},
+    methods: {},
+    constructors: [],
+  );
+  
+  // Cache metadata
+  _typeCache[type] = metadata;
+}
+```
+
+2. Property Registration
+```dart
+static void registerProperty(
+  Type type,
+  String name,
+  Type propertyType, {
+  bool isReadable = true,
+  bool isWritable = true,
+}) {
+  // Validate type registration
+  if (!isRegistered(type)) {
+    throw NotReflectableException(type);
+  }
+  
+  // Create property metadata
+  final metadata = PropertyMetadata(
+    name: name,
+    type: propertyType,
+    isReadable: isReadable,
+    isWritable: isWritable,
+  );
+  
+  // Cache metadata
+  _propertyMetadata
+    .putIfAbsent(type, () => {})
+    [name] = metadata;
+}
+```
+
+3. Method Registration
+```dart
+static void registerMethod(
+  Type type,
+  String name,
+  List<Type> parameterTypes,
+  bool returnsVoid, {
+  List<String>? parameterNames,
+  List<bool>? isRequired,
+}) {
+  // Validate type registration
+  if (!isRegistered(type)) {
+    throw NotReflectableException(type);
+  }
+  
+  // Create method metadata
+  final metadata = MethodMetadata(
+    name: name,
+    parameterTypes: parameterTypes,
+    parameters: _createParameters(
+      parameterTypes,
+      parameterNames,
+      isRequired,
+    ),
+    returnsVoid: returnsVoid,
+  );
+  
+  // Cache metadata
+  _methodMetadata
+    .putIfAbsent(type, () => {})
+    [name] = metadata;
+}
+```
+
+### Instance Creation
+
+```dart
+InstanceMirror createInstance(
+  Type type, {
+  List<dynamic>? positionalArgs,
+  Map<Symbol, dynamic>? namedArgs,
+  String? constructorName,
+}) {
+  // Get constructor metadata
+  final constructors = Reflector.getConstructorMetadata(type);
+  if (constructors == null) {
+    throw ReflectionException('No constructors found');
+  }
+  
+  // Find matching constructor
+  final constructor = constructors.firstWhere(
+    (c) => c.name == (constructorName ?? ''),
+    orElse: () => throw ReflectionException('Constructor not found'),
+  );
+  
+  // Validate arguments
+  _validateArguments(
+    constructor,
+    positionalArgs,
+    namedArgs,
+  );
+  
+  // Create instance
+  final instance = constructor.creator!(
+    positionalArgs,
+    namedArgs,
+  );
+  
+  // Return mirror
+  return InstanceMirror(
+    instance,
+    type,
+  );
+}
+```
+
+### Method Invocation
+
+```dart
+InstanceMirror invoke(
+  Symbol methodName,
+  List<dynamic> positionalArguments, [
+  Map<Symbol, dynamic>? namedArguments,
+]) {
+  // Get method metadata
+  final method = _getMethodMetadata(methodName);
+  if (method == null) {
+    throw ReflectionException('Method not found');
+  }
+  
+  // Validate arguments
+  _validateMethodArguments(
+    method,
+    positionalArguments,
+    namedArguments,
+  );
+  
+  // Invoke method
+  final result = method.invoke(
+    instance,
+    positionalArguments,
+    namedArguments,
+  );
+  
+  // Return result mirror
+  return InstanceMirror(
+    result,
+    result.runtimeType,
+  );
+}
+```
+
+## Performance Optimizations
+
+### 1. Metadata Caching
+- Type metadata cached on registration
+- Method metadata cached on registration
+- Property metadata cached on registration
+
+### 2. Lookup Optimization
+- O(1) type lookup
+- O(1) method lookup
+- O(1) property lookup
+
+### 3. Memory Management
+- Weak references for type cache
+- Lazy initialization of metadata
+- Minimal metadata storage
+
+## Error Handling
+
+### Exception Hierarchy
+```dart
+abstract class ReflectionException implements Exception {
+  final String message;
+  final StackTrace? stackTrace;
+}
+
+class NotReflectableException extends ReflectionException {
+  final Type type;
+}
+
+class InvalidArgumentsException extends ReflectionException {
+  final String memberName;
+  final Type type;
+}
+
+class MemberNotFoundException extends ReflectionException {
+  final String memberName;
+  final Type type;
+}
+```
