Flutter Torrent Streamer

A flutter plugin to stream videos directly from torrent/magnet links.

This plugin is still under development and pull requests to make it better are heavily appreciated

Few Important points to note before using this plugin

• Has only android support for now. (Help to implement iOS support is highly appreciated)
• Is still under development and APIs may go through breaking changes.
• Supports streaming and seeking videos while still being downloaded but is still experimental and has been tested to work on MX Player but does not work with video_player plugin.
