в первый раз «получить создать проект», затем показать «? (Используйте клавиши со стрелками) > Необработанное исключение Flutter Project: оператор нулевой проверки используется для нулевого значения»
Когда я бегу:
get create project
показывать :
? (Use arrow keys)
> Flutter Project
Get Server
затем я получил сообщение:
Unhandled exception:

У меня тоже коррелированная ошибка, когда я пытаюсь активировать get_cli :
когда я бегу
flutter pub global activate get_cli
Я получил сообщение:
Installed executables get and getx.
Warning: Executable "get" runs "bin\get.dart", which was not found in get_cli.
Warning: Executable "getx" runs "bin\get.dart", which was not found in get_cli.
Activated get_cli 1.7.1.
