项目启动不了，有没有大佬求助，版本的问题

[S1lenceStar]

flutter 原本3.4.1 新创建项目的时候 是可以运行的，但是我想学习一下此项目。
此项目版本是 sdk: ">=2.1.0 <3.0.0"
于是我下载后降级 flutter 到版本 2.2.1

运行:
flutter run -d chrome
报错:
The current Dart SDK version is 2.13.1.

Because doubanapp depends on webview_flutter >=2.0.14 which requires SDK version >=2.14.0 <4.0.0, version solving failed.
Running "flutter pub get" in FlutterDouBan-main...
pub get failed (1; Because doubanapp depends on webview_flutter >=2.0.14 which requires SDK version >=2.14.0 <4.0.0,
version solving failed.)

然后我去下载了 Dart @2.15.1 替换掉了 flutter\bin\cache\dart-sdk 的文件夹

运行 flutter run -d chrome 的时候报错:
Can't load Kernel binary: Invalid kernel binary format version.
