Xcode构建完成。无法构建iOS应用程序 - Flutter项目。

我在将Flutter升级到最新稳定版本后遇到了以下错误。已执行所有可能的命令以清除缓存和安装Pods。

你找到解决方案了吗？ - Erick Filho

@ErickFilho，是的，实际上我清理了Flutter缓存，重启了Mac并重新打开了我的IDE和IOS模拟器。似乎是一些缓存问题。尝试清除缓存并重新启动Mac。 - Aravind

Answer 1

某个符号/类被定义了两次。

• 检查链接的框架是否有重复。如果有，请删除重复的部分。
• 清理构建文件夹（Command + Shift + K）。
• 如果是模拟器，请重置模拟器并尝试。
• 如果是设备，请重新启动设备并尝试。
