why it showing below error? AttributeError: 'super' object has no attribute 'getattr'
i want to use image viewer on different screen for creating an app so used this code as testing but it showing error.If i use it kivy code directly without ImageScreen class it works but i need it in ImageScreen class because i want to add more screen in the app. i don't know how to solve this ,.,
