One of the key success factors of Dart is its performance. The Dart VM has a built-in optimizer to increase the execution speed. This optimizer needs a certain amount of execution time before it has enough information to do its work. This is no problem for an app in production, but when testing, you must ensure this condition is met. In this recipe, we are going to focus on how to best benchmark your application.
