StateCosumer<T> class Null safety

StateCosumer

Obtains StateHolder<T> from its ancestors and passes its value to builder.

The StateCosumer widget doesn't do any fancy work. It just calls StateHolder.of in a new widget, and delegates its build implementation to builder.

builder must not be null and may be called multiple times (such as when the StateHolder value change).


How To Use

import 'package:state_holder/state_holder.dart';

Widget foo() {
  return StateConsumer<T"Type of StateHolder">(
    builder : (context, state, child) {
      return SomeWidget();
    },
    child : SomeWidget(), // For State Widget;
    listnable : true/false // if should listen To Changes default [true];
  );
}
