The initState function is called twice when the stateful widget is created because of the way Flutter's framework manages the lifecycle of widgets.

The first time it is called is during the widget creation process, where Flutter first creates the widget tree and initializes all the widgets. This is usually triggered by calling setState() during the build method or when the widget is first created.

The second time it is called is after the widget has been inserted into the widget tree and is ready to be displayed. This is due to the fact that the framework may need to rebuild the widget tree for various reasons, such as when an animation is triggered or when data changes, and thus calls the build method of the widget again, which in turn calls the initState() function again.

In summary, the initState function is called twice to ensure that the widget is properly initialized and reinitialized when necessary, in order to maintain a consistent UI state.
