🚀 Getting Started

Add Dependency

Add the latest stable version of gal to your dependencies:

flutter pub add gal

iOS Setup

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

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

You can copy from example's Info.plist.

Android Setup

Add the following keys to 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 album in API 29

You can copy from example's AndroidManifest.xml.

[!WARNING] Android emulators with API < 29 require SD card setup. Real devices don't.

macOS Setup

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

<key>NSPhotoLibraryAddUsageDescription</key> Required
<key>NSPhotoLibraryUsageDescription</key> Required for saving to album

You can copy from example's Info.plist.

[!WARNING] Flutter currently has a fatal problem for loading info.plist, which may cause permission denials or app crashes in some code editors.

Windows Setup

Update Visual Studio to the latest version for using C++ 20.

[!TIP] If you can't compile, try downloading the latest Windows SDK:

Open Visual Studio Installer

Select Modify

Select Windows SDK

Linux Setup

Linux is not officially supported, but can be added through a non-endorsed federated plugin. See: gal_linux

Handle Errors

// Save Image with try-catch
try {
  await Gal.putImage('$filePath');
} on GalException catch (e) {
  log(e.type.message);
}

// Exception Type
enum GalExceptionType {
  accessDenied,
  notEnoughSpace,
  notSupportedFormat,
  unexpected;
