我运行flutter run --flavor FIRDebugEnabled
我得到了错误：
FAILURE: Build failed with an exception.
* What went wrong:
Task 'assembleFIRDebugEnabledDebug' not found in root project 'android'.
我也尝试过flutter run --flavor FIRAnalyticsDebugEnabled
但是我得到类似的错误：
FAILURE: Build failed with an exception.
* What went wrong:
Task 'assembleFIRAnalyticsDebugEnabledDebug' not found in root project 'android'.
我的目标是使用Firebase Analytics调试视图https://firebase.google.com/docs/analytics/debugview
我在做什么错了？
