Hey Samuel, this is just one of the pieces of my Firebase series. I have Firebase Analytics, Remote Configs and many other tools on the way.Always love to see users releasing source code, and it's nice to know I'm not the only one doing that. It's cool, actually quite common that people do that in this community. Also great you made it free. I have no immediate need for this, but congrats on the hard work and i'm sure this will benefit a lot of users.
