I this is unrelated to the actual issue!

Issue is still reproducible on latest Master & Stable channel.  code sample ```dart import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatelessWidget...

Not sure if this still needs to be implemented but the issue is valid since there is no assertion in the `setState()` method related to calling it during layout. https://github.com/flutter/flutter/blob/5a2153d340f3c591d84d05d4634d34da32006943/packages/flutter/lib/src/widgets/framework.dart#L1203-L1265...
