>* Having null

I must have been spoiled by Flow, Typescript, Kotlin, and Rust, because this (having null implicitly be a member of every type rather than a separate type) has been the major factor in my decision to avoid playing with Dart yet. It's so nice to not have to often manually re-check functions I'm editing to see whether or not each of the parameters are supposed to handle null, and to not have to document that in comments (the same way you usually end up documenting types in a dynamically typed language; this is what I'm using a typed language to get away from!).
