Flutter 3.22版本Web端Chrome构建失败及报错求助

问题现象 #

升级至Flutter 3.22版本后，Web端项目无法在Chrome浏览器完成构建，出现多起依赖web包的报错。已执行flutter clean和flutter pub get命令，问题未解决。

解决步骤 #

• 检查pubspec.yaml，若直接依赖了web包，将版本升级至与Flutter 3.22兼容的版本（如^0.4.0及以上）
• 若未直接依赖web包，执行以下命令更新依赖并清理缓存：
  1. flutter pub cache clean
  2. flutter pub upgrade
  3. flutter pub get
• 若上述方法无效，可在pubspec.yaml中强制指定web包版本：

  dependencies:
    web: ^0.4.0
