How do you measure the effectiveness of your activities?

I measure the effectiveness of my activities in Flutter development through several key indicators:

• Task completion time: how quickly I can implement functionality considering quality.
• Code quality: use of static analysis, test coverage, absence of bugs.
• Application performance: response speed, smoothness of animations, build size.
• Feedback from team and users: how easy my code is to maintain and how satisfied users are with the functionality.

For example, when I introduce a new screen, I evaluate how much time was spent on development, how clean and maintainable the code is, and how it affected the app's responsiveness.
