ReactterComponent<T extends ReactterContext> class
abstract
A abstract StatelessWidget class that provides
the functionality of ReactterProvider with a ReactterContext of T
,
and exposes it through render method.
class App extends ReactterComponent<AppContext> {
const App({Key? key}) : super(key: key);
@override
get builder => () => AppContext();
@override
Widget render(AppContext ctx, BuildContext context) {
return Text("State: ${ctx.stateHook.value}");
}
}
If you don't use builder getter, the instance of T
is not created
and is instead tried to be found it in the nearest ancestor
where it was created.
Use id getter to create or find a instances of T
with an identify:
class App extends ReactterComponent<AppContext> {
@override
get id => "uniqueId";
...
}
Use listenStates getter to listen states, and when it changed, ReactterComponent's render re-built:
class App extends ReactterComponent<AppContext> {
@override
get listenStates => (ctx) => [ctx.stateA, ctx.stateB];
...
}
Use listenAll getter as true to listen all states, and when it changed, ReactterComponent's render re-built:
class App extends ReactterComponent<AppContext> {
@override
get listenAll => true;
...
}
CONSIDER: Dont's use ReactterContext with constructor parameters to prevent conflicts.
