Rebuild Triggers a "skip" in the Discrete Slider

Because the discrete slider is rounded to 40 but it's initial value is 20, the slider has a weird skip on rebuild. The discrete slider's initial value should be set to 40 or the rounding interval should be set to 20.

Or maybe Slider in flutter/flutter should be updated to only apply discretization on value change, NOT on arbitrary interaction or rebuild?

Hi, should I change the initial value of _discreteValue to 40, i.e _discreteValue = RestorableDouble(40) ? thank you

Actually, it's possible that this is no longer needed, this PR was merged yesterday https://github.com/flutter/flutter/pull/103966
