Permissions
iOS requires additional permissions to save to an album. You should make sure it is worth it.
| Android | iOS and macOS | Windows | |
|---|---|---|---|
| Just put | WRITE_EXTERNAL_STORAGE | NSPhotoLibraryAddUsageDescription or NSPhotoLibraryUsageDescription (limited, all) | _ |
| Put to album ur app created (will create) | WRITE_EXTERNAL_STORAGE | NSPhotoLibraryUsageDescription (limited, all) | _ |
| Put to album created by users or other apps | ❌ | NSPhotoLibraryUsageDescription (all) | _ |
In iOS and macOS, it is not possible to save media to an album using only NSPhotolibraryAddUsageDescription. This is a swift limitation. If you have any complaints, please make a request to swift.
Gal.hasAccess(toAlbum: true) returns true when NSPhotoLibraryUsageDescription is limited or all. If you want to put media in an album created by users or other apps, you should avoid using Gal.hasAccess for confirmation.
🚨 If you try to save media in an album created by users or other apps with
NSPhotoLibraryUsageDescriptionset tolimited,galwill create a new album since it cannot reference that album.
Here we will only discuss the versions supported by the latest Flutter stable (Android >= 21, iOS >= 11).
Also, there may be changes in the specifications.
In Android <23, Write permissions to the gallery app are allowed by default.
In Android >=23 && <=29, Writing to the gallery app requires the explicit statement
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="29" /> in the AndroidManifest.xml.
In Android >29, Write permissions to the gallery app are allowed by default.
In iOS >=11, Write permissions to the gallery app requires the explicit statement
<key>NSPhotoLibraryUsageDescription</key> in the info.plist.
In iOS >=14 and macOS , Apple's "Enhanced Privacy Experience" recommends using
<key>NSPhotLibraryAddUsageDescription</key> for write-only.
Even for write-only use, <key>NSPhotoLibraryUsageDescription</key> is required to save to an album.

Talks about the version to which access is not granted by default (Android >=23 && <29).
It will appear until the user checks the "Never show again" box in the dialog
and chooses to reject it, or until the user chooses to reject it from the app settings.
Due to Apple restrictions, it can basically only be displayed once.
