Is it mandatory to call the initState method in every case in the component's lifecycle?

In the lifecycle of a Flutter component (StatefulWidget), the initState method is called once when the state (State) is created and is used for initialization.

It is called necessarily during the first creation of the state object, but not called during subsequent rebuilds of the widget.

If the component does not have state (StatelessWidget), initState is completely absent.

Thus, initState is called exactly once for each instance of the state, but not on every widget update.

Example:

@override
void initState() {
  super.initState();
  // Initialization, for example, setting up listeners or loading data
}
