Flutter 如何获得共享首选项、升级程序和其他软件包的匹配版本？

我有一个升级问题，似乎我不能建立我的应用程序时，它涉及到不同版本的软件包

问题就在这里

      Running "flutter pub get" in Mobile7Merge...                    
      Because requests 3.3.0 depends on shared_preferences ^0.5.2 and no versions of requests match >3.3.0 <4.0.0, requests ^3.3.0 requires shared_preferences ^0.5.2.

      So, because mobile7 depends on both requests ^3.3.0 and shared_preferences ^2.0.3, version solving failed.
      pub get failed (1; So, because mobile7 depends on both requests ^3.3.0 and shared_preferences ^2.0.3, version solving failed.)

在Mobile7Merge中运行“flatter pub get”。。。
因为requests 3.3.0依赖于shared_preferences ^0.5.2，并且没有任何版本的requests match>3.3.0管理依赖关系有时会很麻烦，但我发现以下命令非常有用：


flatter pub过时
flatter pub升级--主要版本
我仍然得到了相同的错误，这里是这样的
，因为mobile7依赖于请求>=3.3.0，它依赖于共享的首选项^0.5.2，共享的首选项^0.5.2是必需的。所以，因为mobile7依赖于共享的首选项>=2.0.3，版本解决失败。
然后尝试依赖项覆盖。这是文件
