我对 Flutter 完全陌生，并接手了这个项目。我不知道是谁做的。我朋友的表弟委托某人做的，但看起来这个项目已经被放弃了。我的朋友想看看我们是否可以启动并运行它。对于让这个 Flutter 项目运行有什么建议吗？
我遇到了多个错误：

一些信息
颤振版本2.5.0 Dart 版本 2.14.0
flutter 和 dart 版本已经过时了。所以你需要做的是升级你的flutter sdk和软件包。
从命令行/终端升级flutter sdk：
flutter upgrade
升级您的套餐：
flutter pub upgrade
flutter clean
清理后，在运行项目之前，首先通过以下方式获取包：
flutter pub get
最后运行你的项目
flutter run
由于迄今为止 flutter 版本差距，我预计您的代码中会出现一些错误。
