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
Tdependency 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.
