title: Uint8List vs List<int> what is the difference?
body: <p>In my flutter project I have some libraries that are using <code>Uint8List</code> (mostly cryptography stuff), and some libraries that are using <code>List&lt;int&gt;</code>(grpc).
  I want to unify a bunch of functions that are working with bytes in best way possible.
  Which cases are appropriate for Uint8List and List (which way is better to work with bytes in dart lang)?</p>
