Move project to Github org

@pinkfish First of all, thanks for this handy package!

It looks like none of the pull requests this year have been merged, and the project appears unmaintained.

Please move the project to a Github org like Flutter Community and add some of the people opening pull requests as maintainers so this project can move forward and take some load off your shoulders.

Seconded. @pinkfish if this no longer being maintained then could this be transferred so the effort that has been put into the plugin doesn't go to waste?

@holocronweaver @MaikuB I created fluttercommunity/community#111. Pleases consider upvoting it.

Due to lack of maintenance in this repo, I have just published a fork on pub.dev.
