Answer 1

首先备份您现有的 ios 文件夹。 删除并运行

    flutter create .

它将生成 ios 文件夹。 构建并运行，您应该一切顺利。

Answer 2

最后我能够通过使用创建一个新项目来解决问题

flutter create -i swift -a kotlin project_name

并将 lib 文件夹移动到那里，而不对 dart 代码进行任何更改。

Answer 3

我遇到了同样的问题。通过清除构建文件夹来修复

Answer 4

请注意，这个问题似乎是当前 Flutter 版本中的一个错误 (1.20.2 bbfbf17)。 它似乎已在 dev 频道的最新 Flutter 版本中修复。

所以如果你可以使用开发频道：

flutter channel dev
flutter upgrade --force
flutter build ios

使用开发频道为我修复了它。

这可能是 1.20.3 中的 hotfixed

从 14.08.2020 发表评论：

修复 #61129 不适用于 1.20 稳定版频道。它是 在 1.21.0-1.0.pre 中可用，目前是开发通道。它是 正在评估 1.20 稳定的修补程序。如果你仍然看到这个 1.21.0-1.0.pre 或更高版本中的问题，请提交新问题并 完整填写模板，以便我们进行调查。

编辑：

这个问题似乎已经解决了。查看发布日志：

https://github.com/flutter/flutter/releases/tag/1.20.3

使用flutter upgrade 将解决此问题。

Answer 5

就我而言，我需要检查构建标志：

Answer 6

flutter create -i swift -a kotlin project_name
cd project_name
flutter run
