iOS Flutter 应用程序无法启动； 'fatal error: ' 相机/CameraPlugin.h'文件未找到'？

Question

我之前在 Android 和 iOS 设备上构建的 Flutter 应用程序。然而，自从实现了相机插件，应用程序将不再构建在 iOS 设备上。

到目前为止我已经尝试过:

注释掉 use_frameworks!在 Podfile 中并尝试了 pod update 和 pod clean。

并将权限添加到 iOS Info.plist 文件中。

我正在运行的代码只是一个默认的 Flutter 应用程序，带有一个选项卡，其中包含来自 https://pub.dartlang.org/packages/camera 的示例代码.

如您所见，它在我的 Android 手机上运行良好。但是，尝试在 iOS 上运行它是行不通的。有谁知道如何解决这一问题？

Answer 1

我建议仍然有这些问题的每个人执行以下步骤:

打开ios文件夹

双击 Runner.xcworkspace(不是 Runner.xcodeproj!)

Pod 安装

构建

问题是 cam 插件不在 Runner.xcodeproj 的范围内。
