我正在使用 VS Code 在 iPhone 5s 上调试我的颤振应用，但它崩溃了，我不知道如何解决这个错误：

PS：在 Flutter 之前我是原生 Android 开发者，所以我不知道如何调试 iOS

我在 Windows 10 上使用 Virtualbox 在 macOS Mojave 10.14.3 上构建 iOS 应用程序

这是我的flutter doctor -v 结果：

      If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location.
      You may also want to add it to your PATH environment variable.

【问题讨论】：

我的应用在安卓设备上运行良好。
如果你进入命令行，导航到你的项目文件夹，然后输入flutter build ios -v，它会返回什么？
这是由 Firebase 配置导致的崩溃。如果您使用为 Android 生成的 .json 文件配置 Firebase，您还需要为 iOS 添加等效的 .plist 文件。您还可以通过 dart 以编程方式配置 Firebase，不需要任何其他文件。
哦，谢谢@danypata，它运行良好，我的应用现在可以 100% 运行！

【解决方案1】：

您仅在以下位置添加了google-services.json 用于 Android 的 Firebase 配置文件：

android > app > google-services.json

您需要为 iOS Firebase 配置添加 GoogleService-Info.plist 文件：

ios > Runner > GoogleService-Info.plist

@danypata 之前在 cmets 中回答过，但你是绝对正确的。
