A plugin service that persist data to Sembast for Angel3 framework.
## Installation
Add the following to your `pubspec.yaml`:
```yaml
dependencies:
angel3_sembast: ^6.0.0
```
## Usage
This library exposes one main class: `SembastService`.
### SembastService
This class interacts with a `Database` and `Store` (from `package:sembast`) and serializes data to and from Maps.
### Querying
You can query these services as follows:
```dart
/path/to/service?foo=bar
```
The above will query the database to find records where 'foo' equals 'bar'.
The former will sort result in ascending order of creation, and so will the latter.
```dart
List queried = await MyService.index({r"query": where.id(Finder(filter: Filter(...))));
```
Of course, you can use `package:sembast` queries. Just pass it as `query` within `params`.
See the tests for more usage examples.
