image_gallery_saver

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 image_gallery_saver as a dependency in your pubspec.yaml file. For example:

dependencies:
  image_gallery_saver: '^1.7.1'

iOS

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

• NSPhotoLibraryAddUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Additions Usage Description in the visual editor

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. In Android version 10, Open the manifest file and add this line to your application tag

<application android:requestLegacyExternalStorage="true" .....>

Example

Saving an image from the internet, quality and name is option

_save() async {
   var response = await Dio().get(
           "https://ss0.baidu.com/94o3dSag_xI4khGko9WTAnF6hhy/image/h%3D300/sign=a62e824376d98d1069d40a31113eb807/838ba61ea8d3fd1fc9c7b6853a4e251f94ca5f46.jpg",
           options: Options(responseType: ResponseType.bytes));
   final result = await ImageGallerySaver.saveImage(
           Uint8List.fromList(response.data),
           quality: 60,
           name: "hello");
   print(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 ImageGallerySaver.saveFile(savePath);
    print(result);
 }
