You have a Dart function that performs an IO operation. To avoid blocking the main thread, you should wrap this operation in a ________.

In Dart, to avoid blocking the main thread when performing IO operations, you should wrap the operation in an Isolate. Isolates are Dart's solution to concurrent programming, allowing you to run code in a separate thread, preventing it from blocking the main thread. By doing so, the application remains responsive, enhancing user experience. Understanding how to use isolates is crucial for managing concurrency and ensuring the smooth execution of asynchronous tasks in Dart applications.
