dart - 无效的版本约束 : Cannot include other constraints with "^"

Question

我正在学习和练习 Flutter 的基础知识，但遇到了这个问题。

代码:

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.2+
  english_words: ^3.1.0

执行命令 --no-color packages get 后出现错误:

Error on line 21, column 20 of pubspec.yaml: Invalid version constraint: Cannot include other constraints with "^" constraint in "^0.1.2+".
  cupertino_icons: ^0.1.2+
                   ^^^^^^^

pub get failed (65)

开发平台: 在 Mac OS Mojave 上运行的 Android Studio 3.4

Answer 1

经过网络搜索，我最终来到这里，我犯的错误是添加了一个尾随逗号

改变了这个

flutter_audio_recorder: ^0.5.5,

到

flutter_audio_recorder: ^0.5.5
