Simple Cubix
// create a cubix
class CounterCubix extends Cubix<int> {
CounterCubix(): super(0);
void increment() => emit(state + 1);
void decrement() => emit(state - 1);
}
void main() => runApp(App());
class App extends StatelessWidget {
@override
build(context) {
return CubixProvider(
// build widget from CounterCubix
// the builder receives BuildContext and Cubix objects
child: CounterCubix.new.build((context, cubix) {
return Column(
children: [
// getting state of cubix
Text(cubix.state.toString()),
ElevatedButton(
// incoking cubix method
onPressed: cubix.increment,
child: const Text('Increment'),
),
ElevatedButton(
onPressed: cubix.decrement,
child: const Text('Decrement'),
)
]
);
})
);
}
}
Auto Sync
class CounterCubix extends Cubix<int> {
CounterCubix(): super(0);
void increment() => emit(state + 1);
void decrement() => emit(state - 1);
}
class DoubleCounterCubix extends Cubix<int> {
late final CounterCubix counterCubix;
DoubleCounterCubix(): super(0);
@override
onCreate(context) {
super.onResolve(context);
// call enableSync to allow this cubix updates whenever its dependency cubixes are updated
// if you want to debouce an update, just call enableSync(debounce: Duration(seconds: 1))
context.enableSync();
counterCubix = context.fromCreator(CounterCubix.new);
}
@override
onInit() {
super.onInit();
emit(counterCubix.state * 2);
}
}
