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.
To use this plugin, add image_gallery_saver
as a dependency in your pubspec.yaml file. For example:
dependencies:
image_gallery_saver: '^1.2.2'
Your project need create with swift. Add the following keys to your Info.plist file, located in /ios/Runner/Info.plist:
You need to ask for storage permission to save an image to the gallery. You can handle the storage permission using flutter_permission_handler.
Saving an image from the internet
_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));
print(result);
}
Saving a video 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);
}
