IWidgetModel class abstract interface

A basic interface for every WidgetModel.

The general approach for the WidgetModel is implement interface that expanded from IWidgetModel. This expanded interface describes the contract which the inheritor of the WidgetModel implemented this interface is providing for the ElementaryWidget. The contract includes all properties and methods which the ElementaryWidget can use for build a part of the tree it describes.

{@tool snippet}

The following is a an example for the top-level factory function that get dependencies using passed BuildContext.

abstract interface class IExampleWidgetModel implements IWidgetModel {
  ListenableState<int> get somePublisher;
  Stream<String> get anotherPublisher;
  Color get justProperty;

  Future<void> doSomething();
  Future<void> anotherOptionOfInteract();
}
