Though a number of the features are exciting, one seems particularly relevant to hardware design: "enhanced enums with members". Previously, with Dart enums you couldn't define the value of an enum which is sometimes a crucial capability that's available in SystemVerilog, for example if you want an enum for opcodes with a sparse encoding. With this new feature, you can add an int or other member variable to an enum, which should make modelling hardware that relies on this type of enum much easier!
