Question

我一直在努力解决一个问题，而且问题越来越令人沮丧。我的flutter android apk可以在android上构建并正常运行，但是我也尝试在iOS模拟器上运行，但是它一直停留在启动屏幕上，并且无法继续使用。

我尝试过的事情。

1）在Xcode的构建阶段将这些文件添加到脚本中。

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

2）在我的FirebaseApp.configure()文件中添加了AppDelegate。

3）重新安装颤振

4）切换到各种颤振通道

这是来自Xcode的错误：

Answer 1

在这种情况下，我建议您：

切换到所需的Flutter频道（例如beta）
使用flutter clean
删除ios目录（删除之前请确保具有备份或git历史记录）
使用以下命令重新创建ios项目：flutter create .在项目目录中运行。这应该创建新的iOS项目
致电flutter pub get

您还可以尝试通过以下方式更新iOS装置：

通过在ios目录中运行pod repo update
通过以下方式重新安装pod：pod install

Flutter IOS应用在运行时卡在启动屏幕上
