pickMultiImages method

Future<List<File>> pickMultiImages({ required BuildContext context, int? maxImages, bool requestFullMetadata = true, })

Picks multiple images from the gallery (iOS 14+; may be limited on older OS).

When features.webFilePicker is set with WebFilePickerFeatureConfig.useFilePickerForMultiPick, uses file_picker on non-web platforms. On web, prefer pickMultiImagesAsXFiles.
