Missing required flag --file after Flutter and Dart SDKs upgrade

I am having a problem running my Flutter App after Windows update. Other than that I am having a few bugs in AndroidManifest.xml
I have tried running flutter doctor but it does not show me what the problem is. I also did flutter clear and then flutter pub get and it did not solve this problem either. Before this message error I updated my Flutter and Dart SDK.
This is also my Andriodmanifest.xml file
`<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.profile_page">

Error running Flutter app on Android Emulator

Im pretty new to Flutter & Im attempting to run an app on the Android Emulator (works fine on the browser but not the emulator). Im getting this error whenever I attempt to run the command 'flutter run':
Error running path. Default activity not found
Unable to read manifest info from
/Users/tazar/Downloads/ethereal-meditations-app-made-app-runnable/build/app/outputs/flutter-a
pk/app.apk.
No application found for TargetPlatform.android_arm64.
Is your project missing an android/app/src/main/AndroidManifest.xml?
Consider running "flutter create ." to create one.
What's really strange about this is that I DO have a declared Main activity in my AndroidManifest.xml file. I have it declared & everything so I don't understand why I'm getting this error in the place. Here is my manifest file in case that can be of use:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
