Overview
A Flutter plugin enabling the display of pop-ups or overlay screens on Android, even when the app is closed or terminated. It leverages Android's system-level overlay permissions to show content above other apps, useful for notifications, quick actions, or persistent UI elements. The plugin integrates seamlessly with Flutter and requires user permission to function. It is designed specifically for Android and does not support iOS. Developers can customize the appearance and behavior of overlays programmatically.
