环境配置 #

Flutter 3.24.5     Dart 3.5.4.    DevTools 2.37.3  pod version: 1.16.2.  url_launcher: ^6.3.1
Hardware Model:      MacBookPro18,3

解决方向 #

• 升级CocoaPods版本：当前pod版本1.16.2较旧，和Flutter 3.24.5可能存在兼容性问题，执行sudo gem install cocoapods升级到最新稳定版
• 更新url_launcher插件：将url_launcher: ^6.3.1升级到最新版本，修改pubspec.yaml后执行flutter pub get
• 清理项目缓存：执行flutter clean，进入ios目录执行pod deintegrate，再重新执行pod install
• 检查插件注册逻辑：确认GeneratedPluginRegistrant是否正确生成，或尝试在AppDelegate中手动注册UrlLauncher插件
• 验证Swift版本兼容性：在Xcode中查看项目的Swift Language Version设置，确保和插件要求的版本一致
