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.
