I run into same error and noticed that if you check isClosed, the screen is not updated. In your code you have to remove the last line from Bloc file:

and put this line in CategoryPage just before the initState(). This way your widget is creating and disposing the bloc. Before, the widget only disposes the bloc but it is never re-created when the widget is re-created.
