saver_gallery

pub package license

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);
 }
