## 1、问题 ##

flutter项目在pubspec.yaml导入url\_launcher包，然后点击Pub get错误提示如下

F:\flutter_sdk\flutter\bin\flutter.bat --no-color pub get
    Running "flutter pub get" in flutter_1...                       
    Error on line 25, column 5 of pubspec.yaml: A dependency may only have one source.

## 2、分析 ##

cupertino\_icons和url\_launcher关键字没有左对齐

# #

##    3、解决办法 ##

让cupertino\_icons和url\_launcher关键字左对齐，然后再点击Pub get更新包就行
