|
## Quick Start
|
|
|
|
### 1. Setup App
|
|
```dart
|
|
void main() {
|
|
runApp(
|
|
const ProviderScope(
|
|
child: MyApp(),
|
|
),
|
|
);
|
|
}
|
|
```
|
|
|
|
### 2. Use in Widgets
|
|
```dart
|
|
class MyPage extends ConsumerWidget {
|
|
@override
|
|
Widget build(BuildContext context, WidgetRef ref) {
|
|
final isAuth = ref.watch(isAuthenticatedProvider);
|
|
return Container();
|
|
}
|
|
}
|
|
```
|
|
|
|
### 3. Access Providers
|
|
```dart
|
|
// Watch (reactive)
|
|
final data = ref.watch(someProvider);
|
|
|
|
// Read (one-time)
|
|
final data = ref.read(someProvider);
|
|
|
|
// Call method
|
|
ref.read(authProvider.notifier).login(user, pass);
|
|
```
|
|
