Я получил эту ошибку:

Перед тем, как залить вас кодом, я хотел бы немного объяснить логику: я пытаюсь реализовать правила игры баккара, чтобы сделать этоЯ установил унаследованный виджет, некоторые виджеты без состояния отправляют входные данные в объект, сохраненный в унаследованном состоянии, в соответствии с этими данными объекта другой виджет перестраивает себя.
последнее изменение, которое я сделал, это применение правил рисования баккара", это может заставить Объект пропустить ввод при необходимости, но когда это произойдет, унаследованный виджет не понравится.
Я опубликую последнюю часть кода, но если вы думаете, что-то ещеУместно просто спросите, и я опубликую это.
Заранее благодарю за помощь
