如何解决“问题”；“格式错误的项目”；生成Flatter iOS应用程序时生成错误

我接手了一个项目，发现自己面临着这个问题。我如何解决它

的文件引用 “Objective-C/TOCropViewController/Models/TOActivityCroppedImageProvider.h” 是多个组（“TOCropViewController”）的成员，并且 “TOCropViewController”）；这表示项目的格式不正确。只有 其中一个组的成员资格将保留（但 目标将不受影响）。如果要引用同一文件 在多个组中，请向同一路径添加另一个引用

---

我通过录音解决了这个问题
