base on flutter中用于保存图片到相册的Plugin # image_gallery_saver
[](https://travis-ci.org/hui-z/image_gallery_saver#)
[](https://pub.dartlang.org/packages/image_gallery_saver)
[](https://choosealicense.com/licenses/mit/)
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:
```yaml
dependencies:
image_gallery_saver: '^2.0.3'
```
## iOS
Your project need create with swift.
Add the following keys to your Info.plist file, located in <project root>/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](https://github.com/BaseflowIT/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
``` dart
_saveLocalImage() async {
RenderRepaintBoundary boundary =
_globalKey.currentContext!.findRenderObject() as RenderRepaintBoundary;
ui.Image image = await boundary.toImage();
ByteData? byteData =
await (image.toByteData(format: ui.ImageByteFormat.png));
if (byteData != null) {
final result =
await ImageGallerySaver.saveImage(byteData.buffer.asUint8List());
print(result);
}
}
_saveNetworkImage() 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
``` dart
_saveNetworkGifFile() async {
var appDocDir = await getTemporaryDirectory();
String savePath = appDocDir.path + "/temp.gif";
String fileUrl =
"https://hyjdoc.oss-cn-beijing.aliyuncs.com/hyj-doc-flutter-demo-run.gif";
await Dio().download(fileUrl, savePath);
final result =
await ImageGallerySaver.saveFile(savePath, isReturnPathOfIOS: true);
print(result);
}
_saveNetworkVideoFile() async {
var appDocDir = await getTemporaryDirectory();
String savePath = appDocDir.path + "/temp.mp4";
String fileUrl =
"https://s3.cn-north-1.amazonaws.com.cn/mtab.kezaihui.com/video/ForBiggerBlazes.mp4";
await Dio().download(fileUrl, savePath, onReceiveProgress: (count, total) {
print((count / total * 100).toStringAsFixed(0) + "%");
});
final result = await ImageGallerySaver.saveFile(savePath);
print(result);
}
```
