我是新的扑动，所以我正在firebase认证工作，并创建了一个扑动firebase项目，但当我运行flutter packages get时，我得到了包错误。
我的输出看起来像这样

Resolving dependencies...
Because every version of flutter_driver from sdk depends on test_api 0.3.0 and mockito >=4.1.2 <=5.0.0-nullsafety.7 depends on test_api ^0.2.19-nullsafety, flutter_driver from sdk is incompatible with mockito >=4.1.2 <=5.0.0-nullsafety.7.
So, because firebase_auth_demo_flutter depends on both flutter_driver any from sdk and mockito ^4.1.2, version solving failed.

错误信息以"Because every version…"其实很清楚。
您需要增加您使用的mockito的版本。你需要使用一个依赖于test_api 0.3.0的mock版本，就像你正在使用的Flutter SDK一样。
当两个包A和B依赖于一个包C时，需要有一个A和B都可以使用的C版本。
