ChangeProviderNotifier update not reflected in Cupertino App tutorial

[KyruCabading]

In the Cupertino App Tutorial Step 5, outdated code is still shown.
See runApp: model: model should be changed to
builder: (context) => AppStateModel()..loadProducts(),

Following the outdated tutorial, I wasn't sure where to call loadProducts() safely.
Luckily this repo is always updated. Found it by looking at the repo, but it may trip up other people following the tutorial as it will;

• Not show any error
• Product Tab List just shows nothing

There was no hint that we need to load products first.

Solution: Update Tutorial Text & Add the "Get the full content on GitHub: lib/model/main.dart." link so people get directed to latest code incase it becomes outdated again.

Thanks!

Just ran into the issue myself. Can we contribute updates to the Codelab somewhere?

While the ChangeNotifierProvider API changed another time, now we should use create not builder like below.

import 'package:flutter/cupertino.dart';
import 'package:flutter/services.dart';
import 'package:provider/provider.dart';

import 'app.dart';
import 'model/app_state_model.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();

  SystemChrome.setPreferredOrientations(
      [DeviceOrientation.portraitUp, DeviceOrientation.portraitDown]);

  return runApp(ChangeNotifierProvider<AppStateModel>(
    create: (context) => AppStateModel()..loadProducts(),
    child: CupertinoStoreApp(),
  ));
}
