saver_gallery #

We use the image_picker plugin to select images from the Android and iOS image library, but it can't save images to the gallery. This plugin can provide this feature.

Usage #

To use this plugin, add saver_gallery as a dependency in your pubspec.yaml file. For example:

dependencies:
  saver_gallery: ^1.0.5

iOS #

Your project need create with swift. Add the following keys to your Info.plist file, located in

<key>NSPhotoLibraryAddUsageDescription</key>
<string>获取相册权限</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>获取相册权限</string>

Android #

You need to ask for storage permission to save an image to the gallery. You can handle the storage permission using flutter_permission_handler. AndroidManifest.xml file need to add the following permission:

    <uses-permission
       android:name="android.permission.WRITE_EXTERNAL_STORAGE"
       tools:ignore="ScopedStorage" />

Example #

Access permission(use permission_handler)

   bool statuses = await (Platform.isAndroid
            ? Permission.storage
            : Permission.photosAddOnly)
        .request()
        .isGranted;

Saving an image from the internet(ig: png/jpg/gif/others), quality and name is option

  _saveGif() async {
    var response = await Dio().get(
        "https://hyjdoc.oss-cn-beijing.aliyuncs.com/hyj-doc-flutter-demo-run.gif",
        options: Options(responseType: ResponseType.bytes));
    String picturesPath = "test_jpg.gif";
    debugPrint(picturesPath);
    final result = await SaverGallery.saveImage(
        Uint8List.fromList(response.data),
        quality: 60,
        name: picturesPath,
        androidRelativePath: "Pictures/appName/xx");
    debugPrint(result.toString());
    _toastInfo("$result");
  }

Saving file(ig: video/gif/others) from the internet

_saveVideo() async {
    var appDocDir = await getTemporaryDirectory();
    String savePath = appDocDir.path + "/temp.mp4";
    await Dio().download("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4", savePath);
    final result = await SaverGallery.saveFile(savePath);
    print(result);
 }
