|
|
|
|
**Replacement of `package:pretty_logging` with breaking changes to support NNBD.**
|
|
|
|
Standalone helper for colorful logging output, using pkg:io AnsiCode.
|
|
|
|
## Installation
|
|
|
|
In your `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
belatuk_pretty_logging: ^6.1.0
|
|
```
|
|
|
|
## Usage
|
|
|
|
Basic usage is very simple:
|
|
|
|
```dart
|
|
myLogger.onRecord.listen(prettyLog);
|
|
```
|
|
|
|
However, you can conditionally pass logic to omit printing an error, provide colors, or to provide a custom print function:
|
|
|
|
```dart
|
|
var pretty = prettyLog(
|
|
logColorChooser: (_) => red,
|
|
printFunction: stderr.writeln,
|
|
omitError: (r) {
|
|
var err = r.error;
|
|
return err is AngelHttpException && err.statusCode != 500;
|
|
},
|
|
);
|
|
myLogger.onRecord.listen(pretty);
|
|
```
