    take: 500,
);
final MediaPage videoPage = await widget.collection.getMedias(
    mediaType: MediaType.video,
    take: 500,
);
final List<Media> allMedias = [
    ...imageRange.items,
    ...videoRange.items,
]
..sort((x, y) => y.creationDate.compareTo(x.creationDate));

Loading more medias in a collection

if (!imagePage.isLast) {
    final nextImagePage = await imagePage.nextPage();
