[Slider] Inactive/unselected stop indicator color is incorrect in the gen_defaults tokens. #153271
Description
Steps to reproduce
New Slider design uses stop indicator color and size for the tick marks in the discrete Slider. However, the new tokens use same color for the active and inactive stop indicator.
flutter/dev/tools/gen_defaults/data/slider.json
Lines 39 to 40 in 9b84701
If we apply this as is then we'll get inactive tick marks with the same color as inactive track color thus rendering them invisible.
Incorrect
Color? get inactiveTickMarkColor => _colors.secondaryContainer;
Corrected
Color? get inactiveTickMarkColor => _colors.primary;
This also seems incorrect in the web specs
Expected results
Correct token
Actual results
Incorrect token
