xcode - Mac 上的 Flutter 项目(从 Windows 复制过来的)

Question

我从 friend 那里收到了 Flutter 项目，用于在 Mac(Catalina 和 Xcode 11.3)上构建应用程序的 iOS 版本。 Flutter 项目是在 Windows 中开发的，也是为 Android 开发的。现在我应该在同一项目的 Mac 上制作 iOS 版本。

我和我的 friend 是 Flutter 的新手。我对 Xcode(构建导出的 Unity 项目)经验不多。

我想了解 Flutter 需要做什么。我可以创建测试项目并在模拟器中运行它。但是这个项目行不通。

flutter doctor -v 的输出似乎没问题:

我尝试清理构建文件夹并重新创建项目:

In order to run your application, type:

  $ cd example
  $ flutter run

Your application code is in example/lib/main.dart.

Your plugin code is in ./lib/TestApp.dart.

Host platform code is in the "android" and "ios" directories under ..
To edit platform code in an IDE see
https://flutter.dev/developing-packages/#edit-plugin-package.

flutter run lib/TestApp.dart

Launching lib/TestApp.dart on iPhone 11 Pro Max in debug mode...
Expected ios/Runner.xcodeproj but this file is missing.
No application found for TargetPlatform.ios.
Is your project missing an ios/Runner/Info.plist?
Consider running "flutter create ." to create one.

flutter build ios lib/alylatu.dart

Expected ios/Runner.xcodeproj but this file is missing.
Application not configured for iOS

我什至尝试将文件从测试项目复制到 TestApp 文件夹，但这没有用。

我应该将 TestApp 项目配置为 iOS 项目吗？我没有安装 Brew。我应该安装那个和其他东西吗？

有什么想法吗？

Answer 1

这对我有用:

1) 创建一个新的 flutter 项目。2) 运行项目并确保其顺利运行。3) 确认项目运行后，转到您的新项目:

• 项目目录
• iOS 文件夹

复制以下内容:

Runner.xcodeproj 和 Runner.xcworkspace

将这些粘贴到您的旧项目 (Project/ios) 中，然后保存并运行。这对我有用，希望它能有所帮助。
