可行解决建议 #

• 清理构建缓存

  • 执行终端命令：flutter clean
  • 进入项目的ios目录，删除Pods文件夹和Podfile.lock文件
  • 执行pod deintegrate，再运行pod install重新安装依赖
  • 打开Xcode，使用快捷键Cmd+Shift+K清理Build Folder

• 重新生成Flutter.framework

  • 执行终端命令：flutter build ios --release --no-codesign，先完成无签名的Release构建
  • 检查生成的framework文件，执行lipo -info /ios/Release-iphoneos/Flutter.framework/Flutter查看架构信息，确认包含arm64架构

• 检查Xcode构建设置

  • 打开Xcode项目，进入Build Settings，确保Architectures设置为Standard Architectures (arm64)
  • 确认Build Active Architecture Only在Release模式下设置为No

• 更新依赖与工具

  • 执行pod repo update更新CocoaPods仓库
  • 备份项目后，执行flutter upgrade升级到最新稳定版Flutter（若当前版本存在已知bug）

• 手动替换Flutter.framework

  • 找到Flutter安装目录下的bin/cache/artifacts/engine/ios-release/Flutter.framework
  • 将该文件复制到项目的ios/Flutter/目录下，替换原有文件
