In what cases does the activate method for a state trigger?

In Flutter, the activate method is called during the State object's lifecycle when the state is attached to the widget tree. This occurs after initState and before didChangeDependencies.

Main cases when activate is triggered:

• When the state is first added to the widget tree.
• When the state is moved to a different location in the tree (e.g., during widget rebuilds).

This method is useful for logic that should run when the state is reattached to the tree, such as subscriptions or state restoration.

Example:

@override
void activate() {
  super.activate();
  print('State activated');
}
