avoid-redundant-async-on-load

added in: 1.0.0 warning.

Warns when a Component's onLoad method can be made sync.

Refactoring async onLoad to sync helps Flame directly continue in it's loading cycle.

Example

Bad:

class MyComponent extends Component {
  Future<void> onLoad() async {
    ... // LINT, has no await
  }
}

Good:

class MyComponent extends Component {
  Future<void> onLoad() async {
    await ...
  }
}

class MyComponent extends Component {
  void onLoad() {
    ...
  }
}
