dart
// 1. Register services anywhere in your app (get_it)
final getIt = GetIt.instance;
getIt.registerSingleton(CounterModel());
// 2. Watch and react to changes automatically (watch_it)
class CounterWidget extends WatchingWidget {
@override
Widget build(BuildContext context) {
final count = watchValue((CounterModel m) => m.count);
return Text('Count: $count'); // Your widget automatically rebuilds on every change
}
}
// 3. Use reactive collections (listen_it)
final items = ListNotifier<String>();
items.add('New item'); // Automatically notifies listeners
// 4. Encapsulate actions with commands (command_it)
final saveCommand = Command.createAsyncNoResult<UserData>(
(userData) async => await api.save(userData),
);
// Access loading state, errors - all built-inNo setState(), no Provider boilerplate, no code generation. Just reactive Flutter.
The Construction Set
💡 Each package works standalone - start with one, add others as needed.
get_it
Dependency injection without the framework
Simple service locator that works anywhere in your app—no BuildContext, no InheritedWidget trees, just clean dependency access.
watch_it
Reactive UI updates, automatically
React to state changes without setState()—watch values and rebuild only what's needed. You'll almost never need a StatefulWidget anymore. Depends on get_it for service location.
command_it
Encapsulate actions with built-in state
Commands that track execution, handle errors, and provide loading states automatically. Handle exceptions the smart way. Perfect for async operations.
listen_it
Combine reactive state in an RxDart-like style that's easy to understand
Transform, filter, combine, and debounce operators for ValueNotifier—plus reactive collections (ListNotifier, MapNotifier, SetNotifier) that automatically notify on changes.
