У меня есть экран авторизации телефона, на котором я проверяю, ввел ли пользователь действительный номер мобильного телефона 10 di git. Если нет, то отображается текст ошибки. Поскольку я новичок в тестах по флаттеру, я не могу понять, как найти текст. Пробовал с использованием find.text, но возвращает:
The following TestFailure object was thrown running a test:
Expected: 'Please enter a valid 10 digit mobile number'
Actual: _TextFinder:<exactly one widget with text "Please enter a valid 10 digit mobile number"
