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.

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

final hasAccess = await Gal.hasAccess(toAlbum: true);
await Gal.requestAccess(toAlbum: true);

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;

  String get message => switch (this) {
        accessDenied => 'Permission to access the gallery is denied.',
        notEnoughSpace => 'Not enough space for storage.',
        notSupportedFormat => 'Unsupported file format.',
        unexpected => 'An unexpected error has occurred.',
