Flutter Isolate

This Flutter application demonstrates the performance difference between performing heavy computations on the main UI thread and offloading them to a separate isolate.

For a deeper understanding of isolates and their use cases in Flutter, refer to this article:

Features:

• Starts a timer that updates every millisecond, simulating background activity.
• Performs heavy calculations (summation) with and without isolates.
• Displays the results of the heavy calculations, highlighting the isolate's benefit for smooth rendering.
• Provides buttons to:
  • Start the timer
  • Stop the timer
  • Run heavy computation with isolate
  • Run heavy computation without isolate
  • Clear computation results

Understanding the Code:

• runHeavyTaskIWithIsolate uses an isolate to perform the heavy computation and returns the result.
• useIsolate is the entry point for the isolate, receiving the data and sending the result back to the main thread.
• runHeavyTaskWithOutIsolate performs the heavy computation on the main UI thread.

Running the App:

1. Clone or download the repository containing the code.
2. Ensure you have Flutter installed (https://flutter.dev/docs/get-started/install).
3. Navigate to the project directory in your terminal.
4. Run flutter run to start the app on a connected device or emulator.

Expected Behavior:

• When the timer is running, you should see smooth updates without lag.
• Running heavy computations without isolates might cause UI stuttering during the calculation and circle loading.
• Heavy computations with isolates should complete without affecting the timer and circle Loading smooth updates.

Benefits of Isolates:

• Isolates prevent heavy computations from blocking the main UI thread, ensuring a responsive and smooth user experience.
• They create a separate memory space for the computation, potentially improving memory management.

Additional Notes:

• The specific performance improvement can vary depending on the complexity of your UI and the nature of the heavy computation.
• Consider using isolates when your app performs long-running tasks that could hinder UI responsiveness.

Feel free to modify the code to experiment with different heavy computations and isolate usage.
