Fixed #

• CRITICAL: Fixed MissingPluginException by properly converting package to Flutter plugin structure
• Moved native Android and iOS implementations from example app to plugin level
• Native implementations are now automatically registered when the package is added to any Flutter app
• Removed duplicate native code from example app that was causing confusion
• Enhanced iOS multiple thumbnail generation with better error handling and resource management

Changed #

• BREAKING: Removed dependency on cross_platform_video_thumbnails - package is now standalone
• Converted package from pure Dart package to proper Flutter plugin
• Implemented direct method channel communication (removed wrapper dependency)
• Changed method channel name from cross_platform_video_thumbnails to video_snapshot_generator
• Native implementations now properly registered via plugin system instead of requiring manual setup
• Example app now relies on plugin registration instead of custom native implementations
• Platform support updated: Android and iOS only (web/desktop support may be added in future)

Technical Details #

• Created android/src/main/kotlin/com/video_snapshot_generator/VideoSnapshotGeneratorPlugin.kt with proper FlutterPlugin implementation
• Created ios/Classes/VideoSnapshotGeneratorPlugin.swift with proper FlutterPlugin implementation
• Added plugin configuration to pubspec.yaml with platform-specific plugin classes
• Added android/build.gradle and ios/video_snapshot_generator.podspec for proper plugin structure
• Replaced cross_platform_video_thumbnails wrapper with direct MethodChannel implementation
• Example app MainActivity.kt and AppDelegate.swift now clean and rely on automatic plugin registration
• Improved iOS thumbnail generation with asynchronous asset loading and resource management

Added #

• Automatic permission handling: The package now automatically requests and handles permissions on Android and iOS
• Automatic storage handling: Thumbnails are automatically saved to platform-appropriate directories with accessible file paths
• Enhanced example app: Complete demo showcasing all package features including:
  • Real video file picker
  • Multiple output format selection (JPEG, PNG, WebP)
  • Display of generated thumbnail images
  • Platform capability checking
  • Multiple frame extraction with horizontal scrollable display
  • Comprehensive error handling

Changed #

• BREAKING CHANGE: maintainAspectRatio now defaults to false to use exact dimensions as specified
• Improved error messages for MissingPluginException with troubleshooting guidance
• Enhanced platform capability checking with fallback defaults

Fixed #

• Fixed MissingPluginException on Android by adding native MethodChannel implementation in MainActivity
• Fixed MissingPluginException on iOS by adding native MethodChannel implementation in AppDelegate
• Fixed multiple frame extraction to display all frames instead of just the first one
• Fixed layout overflow issues in example app with scrollable content

Technical Details #

• Added permission_handler and path_provider dependencies for automatic permission and storage handling
• Implemented PermissionHandler class for cross-platform permission management
• Implemented StorageHandler class for automatic file storage with platform-specific directories
• Native Android implementation using MediaMetadataRetriever for video thumbnail generation
• Native iOS implementation using AVFoundation and AVAssetImageGenerator for video thumbnail generation
• Example app now demonstrates all README features including format selection, platform capabilities, and multiple frame display

Changed #

• BREAKING CHANGE: Replaced video_thumbnail dependency with cross_platform_video_thumbnails
• BREAKING CHANGE: Removed direct dependencies on path_provider and permission_handler
• Updated package to use cross-platform implementation for full platform support
• BREAKING CHANGE: Removed custom output path support - storage is now handled automatically

Added #

• Full cross-platform support: Android, iOS, Web, Windows, macOS, Linux
• WASM compatibility: Full support for Flutter web applications
• Automatic platform detection and initialization
• Cross-platform thumbnail generation with native implementations
• Platform capability checking methods:
  • isVideoFormatSupported() - Check if video format is supported
  • getSupportedVideoFormats() - Get list of supported video formats
  • getSupportedOutputFormats() - Get list of supported output formats
  • isPlatformAvailable() - Check if platform is available

Removed #

• Direct dart:io imports (replaced with platform-agnostic approach)
• Platform-specific permission handling (now handled by cross-platform package)
• Direct file system operations (now handled by cross-platform package)
• Custom output path support - Storage is now handled automatically by the cross-platform package

Technical Details #

• Package now delegates all operations to cross_platform_video_thumbnails
• Uses conditional imports and platform-specific implementations
• Maintains backward compatibility with existing API structure
• All tests continue to pass with new implementation
• The path field in ThumbnailResult is maintained for compatibility but is empty

Added #

• Initial release of video_snapshot_generator package
• Core functionality for generating video snapshots and thumbnails
• Support for multiple output formats (JPEG, PNG, WebP)
• Customizable thumbnail dimensions and quality settings
• Time-based thumbnail generation
• Cross-platform support (Android, iOS)
• Automatic permission handling for Android
• Comprehensive error handling
• Example application demonstrating package usage
• Integration tests for core functionality
• Unit tests for all public APIs
• Comprehensive documentation and README
• Support for generating multiple thumbnails at different time positions
• Custom output path support
• Efficient thumbnail generation using video_thumbnail package
• Platform-specific optimizations
• Detailed API documentation with examples
• MIT license for open source usage
• Flutter lints configuration for code quality
• Analysis options for static analysis
• Support for Flutter SDK 3.10.0+
• Support for Dart SDK 3.0.0+
• Support for Android API level 21+
• Support for iOS 11.0+

Changed #

• Package renamed from flutter_video_thumbnails to video_snapshot_generator
• Class renamed from VideoFrameExtractor to VideoSnapshotGenerator
• Method names updated to reflect thumbnail generation focus
• Documentation updated to reflect new package identity
