ConsumerState<T extends ConsumerStatefulWidget> class abstract Core

The State for a ConsumerStatefulWidget.

It has all the life-cycles if a normal State, with the only difference being that it has a ref property.

It must be used in conjunction with a ConsumerStatefulWidget :

class MyConsumer extends ConsumerStatefulWidget {
 const MyConsumer({Key? key}): super(key: key);

  @override
  ConsumerState<MyConsumer> createState() => _MyConsumerState();
}

class _MyConsumerState extends ConsumerState<MyConsumer> {
  @override
  void initState() {
    // All State life-cycles can be used
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // "ref" is a property of ConsumerState and can be used to read providers
    ref.watch(someProvider);
  }
}
