Pick Multiple Files #
List<MediaFile>? media = await GalleryPicker.pickMedia(context: context);
copied to clipboard
Get All Media Files in Gallery #
GalleryMedia? allmedia = await GalleryPicker.collectGallery();
copied to clipboard
Listen selected files inside gallery picker #
Stream stream = GalleryPicker.listenSelectedFiles;

PickerScaffold #
Gallery Picker could also work as a bottom sheet. Use PickerScaffold instead your Scaffold.
There is an example at example/lib/examples/bottom_sheet_example.dart to see how it could be done.
@override
Widget build(BuildContext context) {
return PickerScaffold(
backgroundColor: Colors.transparent,
onSelect: (media) {},
initSelectedMedia: initMedia,
config: Config(mode: Mode.dark),
body: Container(),
)
}

Customizable destination page #
Within the Gallery Picker you can design a page that will be redirected after selecting any image(s).
Note: There are two builder called multipleMediaBuilder and heroBuilder. If you designed both of them, multipleMediaBuilder will be shown after picking multiple media files, heroBuilder will be shown after picking a single media. If you only designed multipleMediaBuilder, multipleMediaBuilder will be shown after picking any file. Use given hero tag to view your Hero image. You can see a simple example below.
There is an example at example/lib/examples/pick_medias_with_builder.dart to see how it could be done.
GalleryPicker.pickMediaWithBuilder(
multipleMediaBuilder: ((media, context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flippers Page'),
),
body: GridView.count(
crossAxisCount: 3,
mainAxisSpacing: 5,
crossAxisSpacing: 5,
children: [
for (var mediaFile in media)
ThumbnailMedia(
media: mediaFile,
)
],
),
floatingActionButton: FloatingActionButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => MyHomePage(
title: "Selected Medias",
medias: media,
)),
);
GalleryPicker.dispose();
},
child: const Icon(
Icons.send,
color: Colors.white,
),
),
);
}),
heroBuilder: (tag, media, context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flippers Page'),
),
body: Container(
color: Colors.lightBlueAccent,
padding: const EdgeInsets.all(16.0),
alignment: Alignment.topLeft,
child: Hero(
tag: tag,
child: Image.memory(media.thumbnail!),
),
),
floatingActionButton: FloatingActionButton(

medias: [media],
)),
);
GalleryPicker.dispose();
},
child: const Icon(
Icons.send,
