This is a known issue, I forgot to add arrow functions support on class methods. Will be fixed in v0.5 at the latest. In the meantime can replace functions like createState() => PageState() with eg createState() { return PageState(); }
new error after i change State<MyHomePage> createState() => _MyHomePageState(); to State<MyHomePage> createState() { return _MyHomePageState();}

Ok, I know why this error is happening. It's very late for me now though, will fix tomorrow. You can remove the use of widget.title for now to test
