Getting started #

  1. Update kotlin version to 1.6.0 and classpath 'com.android.tools.build:gradle:7.0.4' in your build.gradle
  2. In android set the minSdkVersion to 25 in your build.gradle

Android

Add uses-permission android/app/src/main/AndroidManifest.xml file

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

for android sdk 33 and above

   <uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
   <uses-permission android:name="android.permission.READ_MEDIA_VIDEO"/>

Ios

Add these configurations to your ios/Runner/info.plist file

    <key>NSPhotoLibraryUsageDescription</key>
    <string>Privacy - Photo Library Usage Description</string>
    <key>NSMotionUsageDescription</key>
    <string>Motion usage description</string>
    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>NSPhotoLibraryAddUsageDescription</string>

Usage #

Quick and simple usage example:

Pick Single File #

MediaFile? singleMedia = await GalleryPicker.pickMedia(context: context,singleMedia: true);

Pick Multiple Files #

List<MediaFile>? media = await GalleryPicker.pickMedia(context: context);
GalleryMedia? allmedia = await GalleryPicker.collectGallery;
Stream stream = GalleryPicker.listenSelectedFiles;

Dispose listener

GalleryPicker.disposeSelectedFilesListener();

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(
              backgroundColor: Colors.orange,
              onPressed: () {
                Navigator.push(
                  context,
                  MaterialPageRoute(
                      builder: (context) => MyHomePage(
                            title: "Selected Medias",
                            medias: [media],
                          )),
                );
                GalleryPicker.dispose();
              },
              child: const Icon(
                Icons.send,
                color: Colors.white,
              ),
            ),
          );
        },
        context: context);
GalleryPicker.dispose();

Breaking Changes From 0.2.3 #

BottomSheetLayout changed into PickerScaffold #

Before:

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: BottomSheetLayout(
          config: Config()
          onSelect: (media) {},
          child: Column(
            children: [

Now:

  @override
  Widget build(BuildContext context) {
    return PickerScaffold(
      backgroundColor: Colors.transparent,
      onSelect: (media) {},
      initSelectedMedia: initMedia,
      config: Config(mode: Mode.dark),
      body: Container(),
    )
  }
