如何解决flutter中版本解决失败的问题答案

【问题标题】：How to resolve version solving failed in flutter如何解决flutter中版本解决失败的问题

【问题描述】：

因为flutter_bloc: 0.21.0 依赖于provider: ^3.0.0 并且没有flutter_bloc match: >0.21.0 <0.22.0 的版本，flutter_bloc: ^0.21.0 需要provider: ^3.0.0。所以，因为它告诉我它同时依赖于provider: ^4.1.2 和flutter_bloc: ^0.21.0，所以版本解析失败了。

pub get failed (1; So, because tellz_me depends on both provider ^4.1.2 and flutter_bloc ^0.21.0, version solving failed.)

能分享一下pubspec.yaml文件包吗

看到这个： https://stackoverflow.com/a/67517680/13500457

以及如何自动更新依赖：

我建议您删除所有依赖项并运行 pub get 并使用命令方法添加依赖项，而不是通过复制粘贴。看到这个或上面提到的：

希望对您有所帮助，祝您编码愉快！

【解决方案2】：

你需要使用依赖覆盖。

此代码来自我的项目，因此路径提供程序是问题所在，您需要找到生成的包。冲突并将其放入dependency_overrides 这将解决您的问题。

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.0
  file_picker: ^3.0.0
  hive: ^2.0.0
  hive_flutter: ^1.0.0

dependency_overrides:
  path_provider: 2.0.1
