show static method

Implementation

static void show(
  BuildContext context, {
  required String message,
  Duration duration = const Duration(seconds: 2),
  Color? backgroundColor,
  Color? textColor,
}) {
  final overlay = Overlay.of(context);
  if (overlay == null) return;

  late OverlayEntry entry;
  entry = OverlayEntry(
    builder: (context) => Positioned(
      bottom: 1,
      left: 0,
      right: 0,
      child: Center(
        child: Container(
          padding: const EdgeInsets.symmetric(horizontal: 2, vertical: 1),
          color: backgroundColor ?? Color.black,
          child: Text(
            message,
            style: TextStyle(color: textColor ?? Color.white),
          ),
        ),
      ),
    ),
  );

  overlay.insert(entry);

  Future.delayed(duration, () {
    if (entry.mounted) {
      entry.remove();
    }
  });
