flutterdownloader 的 flutter android gradle 错误

Question

我已经在我的项目中实现了 flutterDownloader （它是一个用于下载 flutter 文件的包），当我像文档所说的那样将其添加到 android 清单时，当我这样做时 gradle 显示此错误

**错误 ： **

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:generateDebugBuildConfig'.
> org.xml.sax.SAXParseException; systemId: file:/C:/Users/fahmi/mscmu/android/app/src/main/AndroidManifest.xml; lineNumber: 27; columnNumber: 35; The prefix "tools" for attribute "tools:node" associated with an element type "provider" is not bound.

我的 Android 清单 -> Android 清单：

这里有什么问题 ？我已经尝试完全按照文档所说的去做，有什么帮助吗？

您必须将工具属性绑定到清单元素：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="[YOUR APP NAME]" xmlns:tools="http://schemas.android.com/tools" >
