Warns when a State has a constructor with non-empty body.

The constructor of a State object should never contain any logic. This logic should always go into State.initState.

Example

❌ Bad:

class _MyHomePageState<T> extends State<MyHomePage> {
  // LINT: Avoid creating constructors for widgets. Try moving the constructor logic to the 'initState' method.
  _MyHomePageState() {
    // ...
  }
}

✅ Good:

class _MyHomePageState<T> extends State<MyHomePage> {
  @override
  void initState() {
    // ...
  }
}
