Layout, Icons, Asset/Network Images are not working on Flutter Release APK

Question

this is the first time I have encountered this problem, where App Layout, Icons, Asset/Network Images are not working on Flutter Release Build.

I already tried cleaning, building multiple times but no luck.

android/app/src/main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.app">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>
   <application

Follow this tutorial: https://docs.flutter.dev/development/ui/assets-and-images

In your pubspec.yaml add:

assets:
    - assets/yourimage.png

Then, you can call your img like:

return const Image(image: AssetImage('assets/yourimage.png'));
