Я пытаюсь реализовать MDNavigation Drawer в моем главном окне. он работал раньше, но я попытался поместить его в макет навигации из-за того, что он оставил пятно на моей главной странице, но теперь то, что раньше работало, больше не работает, и все, что я пытаюсь, выдает мне эту ошибку. Буду признателен за помощь. Спасибо. Ниже трассировка и мой код. Заранее благодарим
