Media Gallery plugin for Flutter

pub package

A Flutter plugin that lists native gallery items.

Installation

First, add media_gallery as a dependency in your pubspec.yaml file.

iOS

Add the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

<key>NSPhotoLibraryUsageDescription</key>
<string>Example usage description</string>

Android

Add the following permissions to your AndroidManifest.xml, located in <project root>/android/app/src/main/AndroidManifest.xml:

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

You should also manage those permissions (for example thanks to the permission_handler plugin). You can see an example for more details.

Usage

Listing media collections

final List<MediaCollection> collections = await MediaGallery.listMediaCollections(
    mediaTypes: [MediaType.image, MediaType.video],
);

Listing medias in a collection

final MediaPage imagePage = await collection.getMedias(
    mediaType: MediaType.image,
    take: 500,
);
final MediaPage videoPage = await 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();
    // ...
}

Getting a file

final File file = await media.getFile();

Getting thumbnail data

final List<int> data = await media.getThumbnail();

Displaying thumbnails

MediaThumbnailProvider, MediaCollectionThumbnailProvider are available to display thumbnail images (here with the help of transparent_image) :

FadeInImage(
    fit: BoxFit.cover,
    placeholder: MemoryImage(kTransparentImage),
    image: MediaThumbnailProvider(
        media: media,
    ),
)

Displaying medias

You can use MediaImageProvider to display an image (here with the help of transparent_image):

FadeInImage(
    fit: BoxFit.cover,
    placeholder: MemoryImage(kTransparentImage),
    image: MediaImageProvider(
        media: media,
    ),
)

To display a video, you can use video_player.
