Isolates in Flutter
Running parallel code in Flutter has never been easy since the introduction of Dart 2.19
I have always wondered what set of code to run in the background to make my app powerful and responsive but I don’t really know how.

You might have heard about isolates but never really understood. Or maybe you might have implemented isolates but the code has always been messy and tedious to write.
