This is a nice example. Could you maybe add some more implementation comments? A novice isn't going to know what's going on here. Maybe more explanation of why a placeholder digit is needed, and around where the animation duration is updated?

Maybe? I want to say "analog digital", but that definitely isn't right. When I think of "digital clock", I think of something with a seven-segment display, and this isn't that.

Good point. A better analog would be the circular digit counters in old pinball machine or a car's odometer. Will update the text.

This example shows how to use
AnimationControllerandSlideTransitionto create an animated digit like you might find on a digital clock. New digit values slide into place from below, as the old value slides upwards and out of view. Taps that occur while the controller is already animating cause the controller'sAnimationController.durationto be reduced so that the visuals don't fall behind.You can try the example here: https://dartpad.dev/?id=9553c20fe0fdb0c5447c1293e02400eb
