You need to use a Theme.AppCompat theme (or descendant) with this activity in Flutter when opening an AAR

Question

I have an issue when I try to open an AAR module from Flutter side. I have implemented the method channel functions to open StartActivity of AAR but when I try to do it, it gives me this error:

E/AndroidRuntime(32503): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.company.appName.devFlavor/com.example.app.StartPageActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

So I did notice that Flutter uses different theming in styles.xm and I decided to use AppCompat but still I'm unable to open the StartActivity intent of AAR.

Here is my values/styles.xml

    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <item name="android:forceDarkAllowed">false</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowDrawsSystemBarBackgrounds">false</item>
        <item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
    </style> 

    <style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowActionBar">false</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

This is how I open the intent from method channels and My MainActivity.kt file:

package com.company.appName

import android.content.Intent
import io.flutter.embedding.android.FlutterActivity
import androidx.annotation.NonNull
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import android.content.Context

class MainActivity: FlutterActivity() {
     private val CHANNEL = "com.company.appName/aarchannel"
     private val AARMETHOD = "aarcall"

    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        MethodChannel(
            flutterEngine.dartExecutor.binaryMessenger,
            CHANNEL
        ).setMethodCallHandler { call, result ->
            if (call.method == AARMETHOD) {
                openAAR(context,result)
            } else {
                result.notImplemented()
            }
        }
}

 private fun openAAR(context: Context, result : MethodChannel.Result){
                val intent = Intent(context, com.example.app.StartPageActivity::class.java)
                startActivity(intent)
                result.success(true)
  }

}

com.example.app is AAR's package name. It actually finds the package but when I try to open as an intent from Flutter side, it gives the error I have mentioned above.

Is there anything I can do to fix Appcompat issue?
