preset: recommended

Checks that super calls in the initState and dispose methods are called in the correct order.

Example

❌ Bad:

class _MyHomePageState<T> extends State<MyHomePage> {
  int _counter = 0;

  @override
  void initState() {
    someWork();

    super.initState(); // LINT
  }

  @override
  void dispose() {
    super.dispose(); // LINT

    someWork();
  }
}

✅ Good:

class _MyHomePageState<T> extends State<MyHomePage> {
  int _counter = 0;

  @override
  void initState() {
    super.initState();

    someWork();
  }

  @override
  void dispose() {
    someWork();

    super.dispose();
  }
}
