Приложение Flutter аварийно завершает работу только на устройстве Android ⇐ Android

[Anonymous]

Мне действительно нужна помощь в этом. Я пробую это уже много дней и до сих пор не могу понять проблему.
Когда я запускаю это приложение в симуляторе iOS, оно работает нормально, но когда я запускаю его на любом устройстве Android, оно работает вылетает сразу. Я не вижу проблемы.
Моя консоль отладки после запуска приложения дает сбой
