flutter_gallery_saver 0.0.6 flutter_gallery_saver: ^0.0.6 copied to clipboard
A new flutter plugin project.
flutter_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 flutter_gallery_saver
as a dependency in your pubspec.yaml file. For example:
dependencies:
flutter_gallery_saver: '^0.0.6'
iOS #
Your project need create with swift. Add the following keys to your Info.plist file, located in
- NSPhotoLibraryAddUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Additions Usage Description in the visual editor
- NSPhotoLibraryUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library 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.
If you target Android 10 (API level 29) or higher, set the value of requestLegacyExternalStorage to true in your app's manifest file:
<manifest ... >
<!-- This attribute is "false" by default on apps targeting
Android 10 or higher. -->
<application android:requestLegacyExternalStorage="true" ... >
...
</application>
</manifest>

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 FlutterGallerySaver.saveImage(
Uint8List.fromList(response.data),
quality: 60,
albumName: "hello");
print("saveImage result: " + result);//这个result在android平台是文件存储地址,在iOS平台是localId;如果是空,就代表保存失败
_toastInfo("$result");
Map map = await FlutterGallerySaver.galleryFileExists(result);
bool isExists = map["isExists"];
String uri = map["uri"];
String msg = map["msg"];
print("isExists: $isExists; uri: $uri; msg: $msg");
}
Saving file(ig: video/gif/others) from the internet
_saveVideo() async {
var appDocDir = await getTemporaryDirectory();
String savePath = appDocDir.path + "/temp.mp4";
String fileUrl =
"https://txmov2.a.yximgs.com/upic/2020/09/06/09/BMjAyMDA5MDYwOTQ1MzZfMTQ4NDI1ODY0XzM1NTk2NTg3NTcyXzFfMw==_b_B3580181bdf842990debc043eb9b5d0bd.mp4?clientCacheKey=3x3a54h46ppw6r9_b.mp4";
await Dio().download(fileUrl, savePath, onReceiveProgress: (count, total) {
print((count / total * 100).toStringAsFixed(0) + "%");
});
final result = await FlutterGallerySaver.saveFile(savePath);
print("saveFile result: " + result);//这个result在android平台是文件存储地址,在iOS平台是localId;如果是空,就代表保存失败
_toastInfo("$result");
Map map = await FlutterGallerySaver.galleryFileExists(result);
bool isExists = map["isExists"];
String uri = map["uri"];
String msg = map["msg"];
print("isExists: $isExists; uri: $uri; msg: $msg");
}
