createOverlayEntries method

@override Iterable<OverlayEntry> createOverlayEntries()

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

Implementation

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

  if (flushbar.blockBackgroundInteraction) {
    overlays.add(
      OverlayEntry(
        builder: (BuildContext context) {
          return Listener(
            onPointerDown:
                flushbar.isDismissible ? (_) => flushbar.dismiss() : null,
            child: _createBackgroundOverlay(),
          );
        },
        maintainState: false,
        opaque: opaque,
      ),
    );
  }

  Widget child = flushbar.isDismissible
      ? _getDismissibleFlushbar(_builder)
      : _getFlushbar();

  overlays.add(
    OverlayEntry(
      builder: (BuildContext context) {
        final Widget annotatedChild = Semantics(
          focused: false,
          container: true,
          explicitChildNodes: true,
          child: AlignTransition(
            alignment: _animation!,
            child: child,
          ),
        );
        return annotatedChild;
      },
      maintainState: false,
      opaque: opaque,
    ),
  );

  return overlays;
