这篇博客记录了在Android Studio中使用Flutter开发时遇到的错误：A dependency may only have one source。问题源于pubspec.yaml文件中依赖项的格式不正确。解决方法是调整依赖项的对齐格式，将`flutter:`部分放在`dependencies:`下，并手动修复代码格式。修复后执行Pubget以确保问题解决。

Android Studio Flutter项目报错A dependency may only have one source. 网上找了问题及解决方案记录如下

Error on line 31, column 5 of pubspec.yaml: A dependency may only have one source.
   ╷
31 │ ┌     sdk: flutter
32 │ │     uses-material-design: true
33 │ │ 
34 │ │ 
35 │ │   # The following adds the Cupertino Icons font to your application.
36 │ │   # Use with the CupertinoIcons class for iOS style icons.
37 │ │   cupertino_icons: ^1.0.2
   │ └──^
   ╵
pub get failed (65;    ╵)
Process finished with exit code 65

原因是
pubspec.yaml 文件添加依赖的内容，特别注意 sdk 对齐格式原因是格式不对，没有对齐
原来格式:

  flutter:
    sdk: flutter
    uses-material-design: true
    cupertino_icons: ^1.0.2
    english_words: ^3.1.0

需要改为如下:

dependencies:
  flutter:
    sdk: flutter
#  uses-material-design: true
  cupertino_icons: ^1.0.2
  english_words: ^3.1.0

Android studio的代码格式化还不起左右,只能自己手动改…
改完后还要记Pub get 一下
实在无语
