MoNotifierProvider<T extends ChangeNotifier> class
A provider that makes a ChangeNotifier value available and triggers rebuilds in descendants when the notifier fires notifications.
Use this for state objects that change over time and need to update the UI. Model extends ChangeNotifier, so it works with MoNotifierProvider.
Named constructor — creates and disposes the notifier:
MoNotifierProvider<PageModel>(
create: (_) => PageModel(),
child: Builder(
builder: (context) {
final model = context.watch<PageModel>();
return Text('${model.count}');
},
),
);
value constructor — uses an externally-held notifier without disposing it:
MoNotifierProvider<PageModel>.value(
value: externalModel,
child: ...,
);
