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: ^3.0.1

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" />
    <!--  if androidExistNotSave = true -->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />   

Example #

Access permission(use permission_handler)

    bool androidExistNotSave = false;
    bool isGranted;
    if (Platform.isAndroid) {
      final deviceInfoPlugin = DeviceInfoPlugin();
      final deviceInfo = await deviceInfoPlugin.androidInfo;
      final sdkInt = deviceInfo.version.sdkInt;
      /// [androidExistNotSave]
      /// On Android, if true, the save path already exists, it is not saved. Otherwise, it is saved
      /// 在安卓平台上,如果是true,则保存路径已存在就不在保存,否则保存
      /// is androidExistNotSave = true,write as follows:
      if (androidExistNotSave) {
        isGranted = await (sdkInt > 33 ? Permission.photos : Permission.storage).request().isGranted;
      } else {
      /// is androidExistNotSave = false,write as follows:
        isGranted = sdkInt < 29 ? await Permission.storage.request().isGranted : true;
      }
    } else {
      isGranted = await 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",
        androidExistNotSave: false,
        );
    debugPrint(result.toString());
    _toastInfo("$result");
  }

Saving file(ig: video/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(file: savePath,androidExistNotSave: true, name: '123.mp4',androidRelativePath: "Movies");
    print(result);
 }
