createOverlayEntries method

@override Iterable<OverlayEntry> createOverlayEntries()

Subclasses should override this getter to return the builders for the overlay.

Implementation

@override
Iterable<OverlayEntry> createOverlayEntries() {
  List<OverlayEntry> overlays = [];

  if (awesomeMessage.overlayBlur! > 0.0) {
    overlays.add(
      OverlayEntry(

              onTap: awesomeMessage.isDismissible!

                  : null,
