Demo

Android

add this to your AndroidManifest.xml

 <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

 <application>
        ...
        <service
           android:name="com.requiemz.overlay_pop_up.OverlayService"
           android:exported="false" />
    </application>

Android 14

applications that target SDK 34 and use foreground service should include foregroundServiceType attribute(see documentation).

 <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

 <application>
        ...
        <service
           android:name="com.requiemz.overlay_pop_up.OverlayService"
           android:exported="false"
           <!-- add this -->
           android:foregroundServiceType="camera, dataSync, location, etc" />
    </application>

Flutter implementation

configure your main.dart entry point a widget to display (make sure to add @pragma('vm:entry-point'))

NOTE: Now you can pass as parameter the dart entry point method name when showOverlay is called

@pragma("vm:entry-point")
void overlayPopUp() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const MaterialApp(
    debugShowCheckedModeBanner: false,
    home: Text('Hello Pub.dev!'),
  ));
}
