![license](https://img.shields.io/github/license/mashape/apistatus.svg)
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: ^3.0.6
iOS
Your project need create with swift.
Add the following keys to your Info.plist file, located in
/ios/Runner/Info.plist:
```
NSPhotoLibraryAddUsageDescription
photo
NSPhotoLibraryUsageDescription
photo
```
## 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](https://github.com/BaseflowIT/flutter-permission-handler).
AndroidManifest.xml file need to add the following permission:
```
```
## Example
Access permission(use [permission_handler](https://pub.dev/packages/permission_handler))
``` dart
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
``` dart
_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
``` dart
_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);
}
```
