Dart DEP for Non-null Types and Non-null By Default (NNBD)
Wanted to leave this here as a stub, as I don't want to forget to open it. A lot of the language in this DEP revolves around pre-Dart 2 semantics...
In Section [I.3.2](https://github.com/chalin/DEP-non-null/blob/master/doc/dep-non-null-AUTOGENERATED-DO-NOT-EDIT.md#i32-language-evolution), add a reference to the recently opened C# issue https://github.com/dotnet/roslyn/issues/227, _Proposal for non-nullable references (and safe nullable references)_.
