If I understand you correctly, you are asking how to update the page every second or minute and display the updated clock. Since it appears to be some corporate app, I would suggest to use a proper state framework. You could for example use a Cubit from BlocLibrary. There you even find a tutorial for a timer which you could more or less copy.
