flutter just_audio_background error: Execution failed for task ':app:processDebugMainManifest'

Am trying to set up just_audio_background but get a bunch of errors (as per screenshot), when I follow the amendments to the main/AndroidManifest.xml and not sure why as appears to follow the steps exactly as the plugin outlines.

The warnings I get are:

And the exception reason I get when I run the app is:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
> com.android.manifmerger.ManifestMerger2$MergeFailureException: Error parsing /Users/mac/Documents/flutter_projects/zense_timer_project/zense_timer/android/app/src/main/AndroidManifest.xml

And here is the AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.WAKE_LOCK"/>

I have run flutter clean and restarted but still can't fix these errrors.

Note possibly related, my AndroidManifest does have these warnings before I make amendments for just_audio_background, but my app still compiles fine and from what I read might be related to a bug in the IDE.

Unresolved class '{applicationName}'
Unresolved class '{applicationName}'
Cannot resolve symbol '@style/NormalTheme'

In your AndroidManifest file,

Change this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">

To this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
