Is it the case that the type names in this list will only match types when they
are defined in a `dart:` library? If so, it would be good to document that
constraint.

Good point! As John suggested, I will add the prefix as part of the element in
`nonnullableTypes`.

nit: we auto-format and auto-sort our source files (so this constant would be
moved after the other static fields)

Thanks! I'm already using `dartfmt` for formatting, but is there anything I can
use for auto-sorting? And if I understand correctly, this constant needs to go
after `bool implicitDynamic = true;`.
