createOverlayEntries method

@override Iterable<OverlayEntry> createOverlayEntries()

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

Implementation

@override
Iterable<OverlayEntry> createOverlayEntries() {
  return <OverlayEntry>[
    _modalBarrier = OverlayEntry(builder: _buildModalBarrier),
    _modalScope = OverlayEntry(
        builder: _buildModalScope,
        maintainState: maintainState,
        canSizeOverlay: opaque),
  ];
}
