Dart was originally a single-threaded programming language. However, many have heard of Isolate. They are often asked about in Flutter developer interviews. For this reason alone, it is worth studying this topic in a little more detail.
Today we will figure out what they are and how they can help us create responsive interfaces that work with 60 fps.
