Did you use any metrics to measure the effectiveness of the application in your previous company?

Yes, to measure the effectiveness of a Flutter app, the following metrics are often used:

• FPS (Frames Per Second) — indicates the smoothness of the interface.
• Response time (Latency) — delay between user action and app response.
• Memory usage — helps identify leaks and optimize resource consumption.
• App startup time — important for user experience.
• CPU profiling — to identify performance bottlenecks.

In my previous company, we used Flutter DevTools to monitor these metrics, along with third-party tools for real-time analytics and performance logging. This helped us promptly identify issues and improve app responsiveness and stability.
