Question

我正在尝试将Firebase添加到我的flutter应用程序中。但是，当我在pubspec_yaml中添加firebase_core依赖项并运行Packages get时，会出现错误。

19-----dependencies:
20-----flutter:
21-----sdk: flutter
22-----firebase_core: ^0.2.5

这是给出错误的代码。

Packages的输出为：

C:\flutter\bin\flutter.bat --no-color packages get
Running "flutter packages get" in trial_one...                  
Error on line 21, column 5 of pubspec.yaml: A dependency may only have one source.
sdk: flutter
^^^^^^^^^^^^^^


pub get failed (65)
Process finished with exit code 65

我遵循了Add Firebase to Flutter网站上的确切说明。但我仍然收到此错误。

Answer 1

缩进实际上不好，这是正确的：

dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^0.3.1+1

希望有帮助！！
