Flutter Isolate | Run tasks in background using Isolates | Multithreading in Flutter

#flutter #dart #flutterdeveloper #isolate

Flutter framework provides a powerful multithreading functionality called 'Isolates' that is been used to run tasks in background which is a great power to handle multitaslking operation.
By using Isolates into your flutter dart code enable a ways to execute dart code parallel which enable app to freely preform computational or heavy load operation without blocking the user interface.

When should you use isolates?
when you run major high end task there are chances that UI will be freezed until the task is completed because dart is a single threaded programming language means is high end task is running then main thread is busy and can't render the UI which is offcource affect user experience. By isolating them in separate threads, isolates ensure that the UI remains responsive and provides a smooth user experience.

To use isolates in Flutter, you need to leverage the compute() and Isolate.spawn() functions provided by the Flutter framework. The compute() function runs a function in a separate isolate and returns the result, while Isolate.spawn() allows you to start a new isolate and execute a given function.

In conclusion, Flutter isolates are a powerful tool for running background tasks, achieving multithreading in flutter, and maintaining a responsive UI. By utilizing isolates effectively, developers can ensure optimal performance, responsiveness, and a seamless user experience in their Flutter applications.
