🚀 Get started

Add dependency

You can use the command to add gal as a dependency with the latest stable version:

$ flutter pub add gal

iOS

Add the following keys to the ios/Runner/Info.plist:

• <key>NSPhotoLibraryAddUsageDescription</key> Required
• <key>NSPhotoLibraryUsageDescription</key> Required for ios < 14 or saving to album

You can copy from Info.plist in example.

Android

Add the following keys to the android/app/src/main/AndroidManifest.xml:

• <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="29" /> Required for API <= 29
• android:requestLegacyExternalStorage="true" Required for saving to the album in API 29

You can copy from AndroidManifest.xml from example.

🔴 Warning: Android emulators with API < 29 require SD card setup. Real devices don't.

🔴 Warning: Flutter currently has a fatal problem for loading info.plist, and permissions are always denied or app crashing in some code editors.
