TextEditingControllerBuilder class

Exposes a TextEditingController to the child, which allows us to convert any TextField into a declarative version.

Typically used for wiring up many state fields to form inputs and making sure everything stays in sync.

If text is updated, the consuming TextField will also be updated. If the ancestor is rebuilt, the composing state will not be lost like it typically is.

TextEditingControllerBuilder(
  text: appState.name,
  builder: (context, controller) {
    return TextField(
      controller: controller,
      onChanged: (value) => appState.updateName(value),
    );
  },
);
