        global screen_manager
        screen_manager = ScreenManager()
        screen_manager.add_widget(Builder.load_string(kv))
        self.title='KivyMD Dashboard'
        self.theme_cls.theme_style = "Dark"
        self.theme_cls.primary_palette = "DeepPurple"
        return screen_manager

MainApp().run()

I was expecting the text and image on the element card created through grid layout but output comes like the below shown pic, without any error given

can anyone help me out with this so that I can get the desired output??

Answer 1

If you add at the start of your kv:

#:import MDCard kivymd.uix.card.MDCard

it seems to work. Doesn't seem like that should be necessary.
