@belalgamal hello!

• deactivate is called when the widget is removed from the tree. However the framework may decide to reinsert into another part of the widget tree. For example, when you are reordering a list of items!
• dispose is called when the widget is removed from the tree permanently! The life cycle of this is terminated.

For more info you can dive deeper into the flutter documentation!

dispose method - State class - widgets library - Dart API

deactivate method - State class - widgets library - Dart API
