Я довольно новичок, чтобы трепетать, поэтому может быть очевидное решение, но я не вижу его.
Всякий раз, когда я запускаю flutter test внутри своего приложения (или любого другого приложения, см. Ниже), я получаю следующую ошибку:

Я опустошил widget_test.dart на случай, если с тестом что-то не так:

import 'package:cfmobile/main.dart';
void main() {
testWidgets('Counter increments smoke test', (WidgetTester tester) async {});

Что я пробовал:
- Я запустил новое приложение с
flutter create и, ничего не меняя, запустил тест внутри приложения. Та же ошибка.
- Думая, что мой SDK как-то поврежден, я загрузил его снова.
flutter clean
Обратите внимание, что сами приложения работают просто отлично. Это просто тест, который продолжает сбой.
Может показаться уместным, что я часто получаю это сообщение об ошибке версии при запуске flutter packages get:
Running "flutter packages get" in cfmobile...
Because every version of flutter_test from sdk depends on http 0.11.3+17 and graphql_flutter 1.0.0-alpha.11 depends on http ^0.12.0, flutter_test from sdk is incompatible with graphql_flutter 1.0.0-alpha.11.
And because no versions of graphql_flutter match >1.0.0-alpha.11 <2.0.0, flutter_test from sdk is incompatible with graphql_flutter ^1.0.0-alpha.11.
So, because cfmobile depends on both graphql_flutter ^1.0.0-alpha.11 and flutter_test any from sdk, version solving failed.
pub get failed (1)
Я решил это, запустив flutter update-packages --force-upgrade, что помогает с этим, но затем появляется сбой.
Я гуглил это и ничего не нашел. Любая помощь будет принята с благодарностью.
