Multithreading in Flutter using Dart isolates

Flutter is a versatile framework for developing cross-platform applications and offers tools like Streams and Futures for handling asynchronous operations. However, to avoid performance issues such as UI jank, developers might need to leverage multithreading by using isolates, which are Flutter's way of achieving concurrency without sharing mutable data between threads. The article explores two primary methods for creating isolates: using the `compute` function and `Isolate.spawn`, both of which allow for running tasks in the background to keep the main thread free. It also discusses advanced usage such as reusing isolates for repetitive tasks and integrating them with stream APIs, as well as utilizing the flutter_isolate package for better management of tasks through a LoadBalancer API. While isolates are beneficial for handling tasks like image manipulation efficiently, it's important to consider their overhead, especially when dealing with large data sets, and the article suggests using TransferrableTypedData to mitigate memory burdens.
