Исключение при нажатии клавиш со стрелками вверх или вниз внутри textFormField ⇐ Android

[Anonymous]

В простой форме, такой как форма входа в систему с двумя TextFormFields для имени пользователя и пароля, когда фокус находится внутри первого поля, когда я нажимаю стрелку вниз, я получаю следующие исключения в консоли:

====================================================================================================

Я ожидаю, что когда я нажму стрелку вниз, фокус переместится на следующий TextFormField, но он выведет исключения. Я могу перемещаться между полями, нажимая Tab или Enter, но клавиши со стрелками вверх и вниз не работают. Есть ли какое-нибудь решение для клавиш со стрелками?
TextFormField(
key: const Key('loginForm_usernameInput_textField'),
textInputAction: TextInputAction.next,
)
