Album saver plugin for Flutter

A Flutter plugin for iOS and Android for saving image to album

Installation

First, add album_saver as a dependency in your pubspec.yaml file.

NOTE: There's a known issue with integrating plugins that use Swift into a Flutter project created with the Objective-C template. See issue Flutter#16049 for help on integration.

iOS

Edit your Podfile as follows:

target 'Runner' do
  use_frameworks! # <--- add this
  ...
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['SWIFT_VERSION'] = '4.2' # <--- add this
    end
  end
end

If you use image_picker plugin, add the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

• NSPhotoLibraryUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Usage Description in the visual editor.
• NSCameraUsageDescription - describe why your app needs access to the camera. This is called Privacy - Camera Usage Description in the visual editor.
• NSMicrophoneUsageDescription - describe why your app needs access to the microphone, if you intend to record videos. This is called Privacy - Microphone Usage Description in the visual editor.

Android

Make sure you add the needed permissions to your Android Manifest Permission.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

File image = await ImagePicker.pickImage(source: ImageSource.gallery);

// Save to ablum
AlbumSaver.saveToAlbum(filePath: image.path, albumName: "YourAlbumName");
