how to resolve "Attribute android: ~ is not allowed here" in android app?

When I run device(emulator) in android studio, it occures some error like below pictures.
enter image description here
I attached code below.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.egolium">
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<application
android:label="egolium"
android:name="${applicationName}"
android:icon="#mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:exported="true"
android:launchMode="singleTop"
android:theme="#style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize"
>

<meta-data

android:resource="#style/NormalTheme"></meta-data>
<!-- android:name="com.google.android.gms.ads.APPLICATION_ID"-->
<!-- android:value="{admob_appId}"-->
/>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<!-- Don't delete the meta-data below.

<meta-data
android:name="flutterEmbedding"
android:value="2" />
</application>
</manifest>
I tried restart in the menu that 'invalidate cache', but it still be same.
or when I remove the codes, it occures more errors
Could you let me know why it occures and how to resolve these?

How to add '.in' domain for flutter app to avoid Android resource linking error?

I'm making a flutter project with the cmd:
flutter create --org in.fiesto lafiesto
This command puts 'in' under backticks- `in` in the MainActivity.kt file because 'in' is a keyword.
When I run the app it throws the following error:
What went wrong:
Execution failed for task ':app:processDebugResources'.
A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction
Android resource linking failed
ERROR:/home/abhi/Documents/Fiesto/lafiesto/build/app/intermediates/packaged_manifests/debug/AndroidManifest.xml:2: AAPT: error: attribute 'package' in tag is not a valid Android package name: '`in`.fiesto.lafiesto'.
This package name in the build/.../AndroidManifest.xml file:
package="`in`.fiesto.lafiesto"
The contents of MAinActivity.kt are:
package `in`.fiesto.lafiesto
import io.flutter.embedding.android.FlutterActivity
class MainActivity: FlutterActivity() {
}
And the android>src> AndroidManifest.xml file has:

I tried changing minSdk, targetSdk, compileSdk and other things in build.gradle file and also tried changing "package=in.fiesto.lafiesto" to "package=`in`.fiesto.lafiesto" in AndroidManifest.xml files but nothing worked.
Please suggest how to deal with this problem.

flutter create -i objc -a java --org in.fiesto lafiesto solved the problem. It created a Java folder under android>src>main which has two folders named "in" and "io", there's no kotlin folder. I don't know if this will have any drawbacks or not!

Flutter-Please ensure that the android manifest is a valid XML document and try again

Here I am getting an error while run flutter project.

Flutter Android Launch Image does not change / display

Flutter 2.10.3
According to doc and this article. launch_image should work fine.
But it is not displayed. When the application is launched, the application icon is displayed, instead of my custom launch_image
As you can see on screenshot below, launch_image is displayed in Android studio.
Background color works fine.
AndroidManifest.xml
