Turbo Shark: A Multithreaded Download Manager

Turbo Shark is a Flutter-based multithreaded download manager designed to efficiently download files by breaking them into segments and downloading them concurrently. This approach significantly speeds up the download process, especially for large files.

Features

• Multithreaded Downloading: Utilizes Dart isolates to download file segments concurrently, improving download speed.
• Progress Tracking: Provides real-time progress updates for each download.
• Download States: Tracks the state of each download (e.g., in progress, done, failed).
• Customizable Segment Count: Allows you to specify the number of segments to use for downloading.
• User-Friendly UI: Simple and intuitive user interface using custom drawer for navigation.
• Theme Support: Supports dark and light themes.

Core Logic

The core download functionality is encapsulated within the ConcurrentFileDownloader class. This class is responsible for:

1. Segmenting Files: Dividing large files into smaller segments for concurrent download.
2. Concurrent Downloads: Utilizing Dart isolates to download these segments simultaneously, improving speed.
3. Progress Updates: Sending real-time progress information back to the main thread to update the UI.
4. State Management: Tracking the state of each download (in progress, complete, failed) and updating the user interface accordingly.

Dependencies

The following pub.dev packages are used in this project:

• provider: For state management.
• google_fonts: For custom fonts in the UI.

You can add these dependencies to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  provider: ^6.1.1
  google_fonts: ^6.1.0

Known Issues/Limitations

• Error Handling: The current error handling is basic. More robust error handling and retry mechanisms can be implemented.
• Resuming Downloads: The current implementation doesn't support resuming interrupted downloads.
• UI Polishing: The UI could be improved with better feedback on loading states and error conditions.
• Platform Specifics: Further platform-specific optimizations might be needed for optimal performance.
• Testing: Further testing would help to find bugs.
