# CherryPick Flutter
|
|
|
|
`cherrypick_flutter` offers a Flutter integration to access and manage dependency injection scopes using the `CherryPickProvider`. This setup facilitates accessing the root scope directly from the widget tree, providing a straightforward mechanism for dependences management within Flutter applications.
|
|
|
|
## Installation
|
|
|
|
Add `cherrypick_flutter` to your `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
cherrypick_flutter: ^1.0.0
|
|
```
|
|
|
|
Run `flutter pub get` to install the package dependencies.
|
|
|
|
## Usage
|
|
|
|
### Importing the Package
|
|
|
|
To begin using `cherrypick_flutter`, import it within your Dart file:
|
|
|
|
```dart
|
|
import 'package:cherrypick_flutter/cherrypick_flutter.dart';
|
|
```
|
|
|
|
### Providing State with `CherryPickProvider`
|
|
|
|
Use `CherryPickProvider` to encase the widget tree section that requires access to the root or specific subscopes:
|
|
|
|
```dart
|
|
import 'package:flutter/material.dart';
|
|
import 'package:cherrypick_flutter/cherrypick_flutter.dart';
|
|
|
|
void main() {
|
|
runApp(
|
|
CherryPickProvider(
|
|
child: MyApp(),
|
|
),
|
|
);
|
|
}
|
|
```
|
|
|
|
Note: The current implementation of `CherryPickProvider` does not directly pass a `rootScope`. Instead, it utilizes its methods to open root and sub-scopes internally.
|
|
|
|
### Accessing State
|
|
|
|
Access the state provided by `CherryPickProvider` within widget `build` methods using the `of` method:
|
|
|
|
```dart
|
|
class MyWidget extends StatelessWidget {
|
|
@override
|
|
Widget build(BuildContext context) {
|
|
final CherryPickProvider cherryPick = CherryPickProvider.of(context);
|
|
final rootScope = cherryPick.openRootScope();
|
|
|
|
// Use the rootScope or open a subScope as needed
|
|
final subScope = cherryPick.openSubScope(scopeName: "exampleScope");
|
|
|
|
return Text('Scope accessed!');
|
|
}
|
|
}
|
|
```
|
|
|
|
### Updating State
|
|
|
|
The `CherryPickProvider` setup internally manages state updates. Ensure the `updateShouldNotify` method accurately reflects when the dependents should receive updates. In the provided implementation, it currently does not notify updates automatically.
|
|
|
|
## Example
|
|
|
|
Here is an example illustrating how to implement and utilize `CherryPickProvider` within a Flutter application:
|
|
|
|
```dart
|
|
class MyApp extends StatelessWidget {
|
|
const MyApp({super.key});
|
|
|
|
@override
|
|
Widget build(BuildContext context) {
|
|
final rootScope = CherryPickProvider.of(context).openRootScope();
|
|
|
|
return MaterialApp.router(
|
|
routerDelegate: rootScope.resolve<AppRouter>().delegate(),
|
|
routeInformationParser:
|
|
rootScope.resolve<AppRouter>().defaultRouteParser(),
|
|
);
|
|
}
|
|
}
|
|
```
|
|
|
|
In this example, `CherryPickProvider` accesses and resolves dependencies using root scope and potentially sub-scopes configured by the application.
