1. Identify CPU-bound or I/O-bound tasks causing UI blockage.
2. Choose between `async/await`, `Isolate.run()`, or `Isolate.spawn()` based on task characteristics.
3. Implement asynchronous operations using `async/await` and `FutureBuilder` for simple I/O.
4. Offload short-lived heavy computations using `Isolate.run()`.
5. Establish long-lived worker isolates using `ReceivePort` and `SendPort` for continuous background processing.
6. Ensure proper message passing and data handling between isolates.
7. Test and optimize for performance, memory usage, and UI responsiveness.
