flutter_gallery_saver 0.0.7

Flutter Android iOS

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: '^0.0.7'

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>

    await Dio().download(fileUrl, savePath, onReceiveProgress: (count, total) {
      print((count / total * 100).toStringAsFixed(0) + "%");
    });
    final result = await FlutterGallerySaver.saveFile(savePath);
