What is the sequence of method calls in the lifecycle of a State object?

The lifecycle of a State object in Flutter includes the following main methods, called in a specific sequence:

1. constructor — an instance of State is created.
2. initState() — called once when the State is initialized, usually to initialize data and subscribe to streams.
3. didChangeDependencies() — called immediately after initState and when dependencies change, for example, if an InheritedWidget changes.
4. build() — called every time the widget needs to be rendered, for example, after setState.
5. didUpdateWidget() — called if the parent widget changes and the state needs to be updated.
6. setState() — manually called to update the state and trigger a rebuild.
7. deactivate() — called when the State is temporarily removed from the widget tree.
8. dispose() — called when the State is permanently removed, to free resources.

An example of a simplified lifecycle:

class MyWidgetState extends State<MyWidget> {
  @override
  void initState() {
    super.initState();
    // initialization
  }

  @override
  void didChangeDependencies() {
    super.didChangeDependencies();
    // respond to dependency changes
  }

  @override
  Widget build(BuildContext context) {
    return Container();
  }

  @override
  void dispose() {
    // free resources
    super.dispose();
  }
}
