Flutter canonical implementation of a builder pattern

Thanks for letting me know! The code in this repository is not canonical in any way, cause when I wrote it I used react native/ios patterns, since it was the only thing I knew. I will make sure to follow more best practices on a v2 branch!

[vasilich6107]

sure, I can do a PR if it works for you

[demchenkoalex]

if it is a non breaking one, you can :)

@demchenkoalex it's definetely breaking and probably suitable for v2 cause all *Builder methods will receive additional parameter
