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，您应该会很好。

Answer 2

我有同样的问题。通过清除构建文件夹进行修复

Answer 3

请注意，此问题似乎是当前版本（1.20.2 bbfbf17）中的错误。它似乎已在开发人员频道的最新版本中得到修复。

因此，如果您可以使用开发频道：

flutter channel dev
flutter upgrade --force
flutter build ios

使用开发者频道为我修复了该问题。

在1.20.3中可能是hotfixed

对自14.08.2020起的问题的评论：

1.20稳定通道上没有修复程序＃61129。它是在1.21.0-1.0.pre中可用，这是当前的dev通道。它是正在评估1.20稳定修补程序。如果您仍然看到此 1.21.0-1.0.pre或更高版本中的问题，请提交新的问题并完全填写模板，以便我们进行调查。

查看1.20.3的樱桃小贴士：https://github.com/flutter/flutter/pull/64984

编辑：

此问题似乎已解决。请参阅发布日志：

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

使用flutter upgrade将解决此问题。

Answer 4

最后，我能够通过使用创建新项目来解决该问题

flutter create -i swift -a kotlin project_name

，然后将lib文件夹移至该文件夹，而无需更改dart代码。

Answer 5

就我而言，我需要检查build标志：

Answer 6

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

Flutter：该应用未针对iOS构建
