Flutter – Overlay

Create an overlay-widget. A widget which is floating on top of all other widgets on the screen.

void showHelp(context) {
    late OverlayEntry entry;
  
    entry = OverlayEntry(
      builder: (context) => Material(
        color: Colors.transparent,
        child: Container(
          margin: const EdgeInsets.all(20),
          padding: const EdgeInsets.all(20),
          color: const Color.fromARGB(230, 65, 55, 49),
          child: Text('Overlay'),
        ),
      ),
    );
  
    final overlay = Overlay.of(context)!;
    overlay.insert(entry);
  }
