AndroidManifest.xml:3: error: resource mipmap/launcher_icon (aka com.xyz.dbdb:mipmap/launcher_icon) not found

In the process of generating a .aab file for Google Play Store am trying to run the following command as a part of the process:

aapt2.exe link --proto-format -o base.zip -I android.jar --manifest decompile_apk\AndroidManifest.xml

And at the end of processing I get these errors:

decompile_apk\AndroidManifest.xml:3: error: resource mipmap/launcher_icon (aka com.xyz.dbdb:mipmap/launcher_icon) not found.
decompile_apk\AndroidManifest.xml:4: error: resource style/LaunchTheme (aka com.xyz.dbdb:style/LaunchTheme) not found.
decompile_apk\AndroidManifest.xml:5: error: resource style/NormalTheme (aka com.xyz.dbdb:style/NormalTheme) not found.
error: failed processing manifest.

Files that I have are as follows

D:\myproject\android\app\src\main\res\drawable\launch_background.xml
D:\myproject\android\app\src\main\res\drawable-v21\launch_background.xml
D:\myproject\android\app\src\main\res\mipmap-hdpi\launcher_icon.png
D:\myproject\android\app\src\main\res\mipmap-mdpi\launcher_icon.png

D:\myproject\android\app\src\main\res\values\styles.xml
D:\myproject\android\app\src\main\res\values-night\styles.xml

My AndroidManifest.xml is as follows:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application
        android:label="DBDB"
        android:name="${applicationName}"
        android:icon="@mipmap/launcher_icon">
        <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"

            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <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.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

Any clue how to resolve these issues:

After a lot of wrangling with various option and not receiving any answer here I shifted my project from Visual Code to Android Studio. Recompile the project there. Signed the AAB and uploaded to Google Play Store successfully.
