RtComponent<T extends Object> class
abstract
A abstract StatelessWidget class that provides RtProvider features,
whose dependency of T
type defined is exposing trough render method.
class App extends RtComponent<AppController> {
const App({Key? key}) : super(key: key);
@override
get builder => () => AppController();
@override
Widget render(BuildContext context, AppController inst) {
return Text("State: ${inst.stateHook.value}");
}
}
Use builder getter to define the dependency creating method.
class App extends RtComponent<AppController> {
@override
get builder => () => AppController();
...
}
NOTE: If you don't use builder getter, the
T
dependency is not created and instead tried to be found it in the nearest ancestor where it was created.
Use id getter to identify the T
dependency:
class App extends RtComponent<AppController> {
@override
get id => "uniqueId";
...
}
Use listenStates getter to define the states and with its changes rebuild the Widget tree defined in render method.
class App extends RtComponent<AppController> {
@override
get listenStates => (inst) => [inst.stateA, inst.stateB];
...
}
Use listenAll getter as true
to listen all dependency changes to rebuild
the Widget tree defined in render method.
class App extends RtComponent<AppController> {
@override
get listenAll => true;
...
}
RECOMMENDED: Dont's use Object with constructor parameters to prevent conflicts.
