How to force Flutter to rebuild / redraw all widgets?

Question

Is there a way to force Flutter to redraw all widgets (e.g. after locale change)?

Answer 1

I explain how to create a custom 'AppBuilder' widget in this post.

You can use the widget by wrapping your MaterialApp with it, for example:

Widget build(BuildContext context) {
  return AppBuilder(builder: (context) {
    return MaterialApp(
      ...
    );
  });
}

You can tell the app to rebuild using:

AppBuilder.of(context).rebuild();
