I'm really sorry all!

Been dealing with some work stuff and had notifications turned off for most of my flutter packages until recently. I'll get back on track of this repo soon and I'll also add a note to the readme for other possible contributors so this package doesn't fall into the same rut. In meantime @phamconganh wrote a fix for these issues and I hope to release that version this weekend once I've tested it and added some more tests

[Bes79]

are there any fixes?

[stargazing-dino]

I just uploaded v0.0.12 to pub which should be null issue free.

I really want to fix how we do controllers before I land a major v1.0 release but I dunno if I'll have time. Anyways, I'm looking for a reliable contributor to add to the project and have added a note to bottom of readme as well so hopefully the long silence won't happen again!
