在项目或库中找不到清单io.flutter.app.FlutterApplication中引用的类

问题描述

需要一些帮助，我才刚刚起步，不知道我的AndroidManifest.xml文件有什么错误。在android：name =“ io.Flutter.app.FlutterApplication”，android：name =“。MainActivity ”。在元数据中也有错误。我不知道该文件是否已损坏，我已经打开了其他Android Flutter项目，并且在AndroidManifest.xml文件中具有相同的错误，但是APP正常运行，没有任何错误或任何其他内容。现在我添加的权限不起作用。

<!-- io.Flutter.app.FlutterApplication is an android.app.Application that
     calls FlutterMain.startinitialization(this); in its onCreate method.
     In most cases you can leave this as-is,but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->
<application
    android:name="io.Flutter.app.FlutterApplication"

             to determine the Window background behind the Flutter UI. -->

             Drawable until Flutter paints its first frame,then this splash
             screen fades out. A splash screen is useful to avoid any visual
             gap between the end of Android's launch screen and the painting of
             Flutter's first frame. -->
