Dart generics variance

Title
Dart generics variance
Description
Covariant generics fit a common intuition that programmers have, and very often this intuition is correct, such as in the common “read-only” use of a generic. Although this intuition isn’t always correct, Dart is erring on the side of convenience by having covariant generics.
