Also worth your time
Before moving on: Solve 15 exercises on Exercism in your language, then write a small console program, such as a to-do list or a grade calculator, that uses classes, collections, error handling and one async call.
Dart is quick to pick up if you know Java, JavaScript or C#, so spend your time on null safety, Futures and Streams rather than syntax. Use DartPad in the browser for the first week so setup does not slow you down.
