Losing state on orientation change about scoped_model HOT 4 CLOSED

Hey @andrewpmoore. Every time the orientation changes, it's going to call the build function again. That means you are recreating the new AppModel() on every build (hot reload would do the same thing).

To fix the issue, you need to create and store the AppModel in a State object. Something like this:

class MyApp extends StatefulWidget {
  @override
  MyAppState createState() {
    return new MyAppState();
  }
}

class MyAppState extends State<MyApp> {
  AppModel appModel;
  
  @override
  void initState() {
    appModel = new AppModel();
    super.initState();
  }
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Counter Example',
      theme: ThemeData.dark(),
      home: new ScopedModel<AppModel>(
        model: appModel,
        child: new FirstScreen(),
      ),
    );
  }
}

That's perfect, thanks for that. It's working a treat now 👍
