Description:
add to gallery
Add to Gallery #
Adds images and videos to the Android Gallery and iOS Photos
View example app
Installation #
Add add_to_gallery as a dependency in your pubspec.yaml file.
Permissions #
You need the following permissions in your app:
iOS
NSPhotoLibraryUsageDescription
This allows the plugin to use the PHPhotoLibrary APIs to add assets to the user's photo library.
Android
READ_EXTERNAL_STORAGE
WRITE_EXTERNAL_STORAGE
If you target Android 10, you will also need the requestLegacyExternalStorage="true" in your AndroidManifest.
This plugin does not manage permissions for you. By excluding permissions from our plugin we have created a simple, reliable plugin.
We recommend using permission_handler to handle permissions.
Usage #
There's only one method. It copies the source file to the gallery and returns the new file.
File file = await AddToGallery.addToGallery(
originalFile: File('/Some/Media/Path.jpg'),
albumName: 'My Awesome App',
deleteOriginalFile: false,
);
print("Savd to gallery with Path: ${file.path}");

Using permission_handler, this may look like:
try {
// iOS
if (!await Permission.photos.request().isGranted) {
throw ('Permission Required');
}
// Android (10 and below)
if (!await Permission.storage.request().isGranted) {
throw ('Permission Required');
}
// Add to the gallery
File file = await AddToGallery.addToGallery(
originalFile: File('/Some/Media/Path.jpg'),
albumName: 'My Awesome App',
deleteOriginalFile: true,
);
print("Savd to gallery with Path: ${file.path}");
} catch(e) {
print("Error: $e");
}

Example app #
The example app shows a few more edge-cases in action.
Uses permission_handler to request permissions
Uses image_picker to take photos with the camera
Copies assets to the gallery
Uses shared_preferences to save and read the file path locally
This shows that the assets are still accessible between reboots
Credits & Comparison #
Add to Gallery is based on gallery_saver with some notable differences. Enough to warrant a new package rather than a pull-request. Generally speaking, I've simplified the API and unified the behaviour on iOS and Android. It also supports scoped storage on Android (which will be enforced with Android 11)
Big thanks to the Tecocraft LTD team for Android functionality on Android 10 and 11.

👎 The file path is not returned
🔥 The original file path is correct
Android and iOS
🔥 Source file is copied to the getApplicationDocumentsDirectory for persistence
🔥 Your app has permission to access the file
🔥 The new file path is returned

Permissions
Handled within the plugin. The first-call fails silently due to permissions race-condition
Not handled within the plugin
An Important Note about Google photos #
Google Photos has a built-in feature to remove exact duplicates. It can be confusing to see your media disappearing like this. I considered addressing this behaviour in the plugin, but decided against it. I expect plugin users to be creating unique images with the camera or other methods.
