using TickerProviderStateMixin
pishguy opened this issue · comments
in MVVM model as this library how can i implement TickerProviderStateMixin
or SingleTickerProviderStateMixin
the same as StatefulWidget
? i know i can separate part of code as a simple class but i want to use in main class
Hi. There are some ready-to-use mixins for ticker provider. https://github.com/Elementary-team/flutter-elementary/blob/main/packages/elementary/lib/src/ticker/ticker_providers.dart
They are should be applied to WidgetModel.
@MbIXjkee could you tell me how can i implement createTicker
method and implementing AnimationController
or TabController
with that?
for example this is my simple viewModel
class:
LocationScreenWidgetModel defaultLocationScreenWidgetModelFactory(BuildContext context) {
final model = context.read<LocationScreenModel>();
return LocationScreenWidgetModel(model,);
}
class LocationScreenWidgetModel extends WidgetModel<LocationScreenWidget, LocationScreenModel>
implements ILocationScreenWidgetModel, SingleTickerProviderWidgetModelMixin {
LocationScreenWidgetModel(super.model);
///
@override
Ticker createTicker(TickerCallback onTick) =>Ticker(onTick);
}
abstract class ILocationScreenWidgetModel implements IWidgetModel {
///
}
thanks
You don't need to implement createTicker, there is packages/elementary/lib/src/ticker/ticker_providers.dart with mixins that are already implemented everything needs to be a tickerProvider. When you need AnimationController, you just create it inside WM (with mixin) and provide this
inside as a ticker provider.
