just_save_gallery #

A lightweight Flutter plugin that just saves images and videos to the device gallery. No read, no delete, no list — just save.

Supports both raw bytes and file path inputs on Android and iOS.

Features #

• Save images and videos from Uint8List bytes
• Save files directly from a file path (memory-efficient for large videos)
• Custom album/folder names
• Automatic file name numbering to avoid duplicates
• Built-in permission handling (with opt-out)
• Typed error handling via SaveException

Installation #

dependencies:
  just_save_gallery: ^0.1.0

Setup #

Android #

No additional setup required. The plugin declares WRITE_EXTERNAL_STORAGE (maxSdkVersion 28) automatically.

iOS #

Add the following key to your ios/Runner/Info.plist:

<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app saves photos and videos to your photo library.</string>

If you use the albumName parameter, you must also add read/write access:

<key>NSPhotoLibraryUsageDescription</key>
<string>This app accesses your photo library to save media into albums.</string>

Usage #

import 'package:just_save_gallery/just_save_gallery.dart';

final gallery = JustSaveGallery();

Save image from bytes #

final uri = await gallery.saveImage(
  imageBytes,
  name: 'photo.jpg',
  albumName: 'My Album',
);

Save video from bytes #

final uri = await gallery.saveVideo(
  videoBytes,
  name: 'clip.mp4',
  albumName: 'My Videos',
);

Save file from path #

final uri = await gallery.saveFileToGallery(
  '/path/to/video.mp4',
  albumName: 'Downloads',
);

The media type is inferred from the file extension automatically.

Error handling #

try {
  await gallery.saveImage(bytes, name: 'photo.jpg');
} on SaveException catch (e) {
  switch (e.code) {
    case SaveErrorCode.permissionDenied:
      // Handle permission denied
      break;
    case SaveErrorCode.diskFull:
      // Handle disk full
      break;
    case SaveErrorCode.invalidFormat:
      // Handle invalid format
      break;
    case SaveErrorCode.fileNotFound:
      // Handle file not found
      break;
    case SaveErrorCode.unknown:
      // Handle unknown error
      break;
  }
}

Disable automatic permission request #

await gallery.saveImage(
  bytes,
  name: 'photo.jpg',
  requestPermission: false, // Handle permission yourself
);
