Why my Flutter app is not building while executing?

I have been trying to build a flutter app. But while exporting/building it an error came. The error message while building:

Flutter - AndroidManifest.xml corrupted after Flutter Upgrade

I've just upgraded to Flutter 2 and upgraded an application along with it. I followed all the steps to upgrade the application, but now I can't seem to run the app because my AndroidManifest.xml file seems corrupted.
Here is the xml file (I've also added comments where the errors are appearing).

I've seen elsewhere that people are just completely rebuilding their projects (as in completely generating a new project, stripping business logic from their Flutter 1.x app and copying it across to a Flutter 2.x app). Does anyone know what's happened to my XML file?

The best solution is to downgrade the Flutter . after that update AndroidManifest file

Class referenced in the manifest, io.flutter.app.FlutterApplication, was not found in the project or the libraries

need some help I am just new to flutter and don't know what is the error on my AndroidManifest.xml file.In android:name="io.flutter.app.FlutterApplication" ,android:name=".MainActivity". also in Metadata has errors. I don't know if the file is corrupted or not, I have opened other Android flutter projects and it has all the same error on the AndroidManifest.xml file but the APP was running with no errors or anything. now the permissions I add is not working.
`
<uses-permission android:name="android.permission.ACCES_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCES_COARSE_LOCATION"/>

That's normal because the Flutter SDK doesn't have code check for Android code. Even if there are warnings thrown from the Android code, you should still be able to run the Flutter app if the Android code doesn't have "real" errors.
What you can do here is to enable code completion for Java/Kotlin on Preferences > Language & Frameworks > Flutter > Experiments. This should remove the warnings thrown on the Android project even if the code is correct.
... or click on Tools > Flutter > Open Android module in Android Studio. This should open the Android build of the Flutter project on Android Studio and help check if the warnings given are correct.

what is the problem here ? I have tried to do exactly what the docs says , any help ?

you have to bind the tools attribute to your manifest element:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="[YOUR APP NAME]" xmlns:tools="http://schemas.android.com/tools" >

I just solved it! You need to add this line to the manifest tag it's actually the first tag in the file: xmlns:tools="http://schemas.android.com/tools"
