preface
At the beginning of the development of flutter, there are all kinds of problems. At this time, it is a little difficult for the developers who have just contacted the development of flutter. Therefore, in the early stage of the development of flutter, we should accumulate more, consult more and step on more holes, so that we can start to develop the flutter project quickly. This article will share a relatively simple problem encountered in the development of flutter, the error prompted after the operation of flutter packages get.
Error message
After running the flutter packages get, the flutter project will prompt the following error prompt:
After executing the command flutter packages get, an error is reported. It is about the Android related prompt in the flutter project

Through the above error prompt, the editor has told the specific location of the error file, so follow the file path of the prompt and enter the corresponding file to check the specific location of the error. However, after checking, no error is found. After performing the flitter clean, the editor runs the flitter run again, and the error is still reported. The corresponding writing method of the specific file is as follows:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.platform_app">
<uses-permission android:name="android.permission.INTERNET"/>
<application

<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>

<application
android:name="io.flutter.app.FlutterApplication"
android:label="platform_app"
android:icon="@mipmap/ic_launcher">
<activity...
Finally, click save file, run the project again, and no error will be reported directly. The project flutter is successfully started, and the problem is perfectly solved.
