Default foreground color animation duration doesn't apply on icon of Button widgets #162301
Description
Steps to reproduce
- Create a new Flutter project
- Use the
ElevatedButton.icon()widget and specify aniconandlabelwidget - Override the
styleproperty to the following:style: ButtonStyle( foregroundColor: WidgetStateProperty.resolveWith<Color?>( (states) => states.contains(WidgetState.hovered) ? Colors.white : Colors.white24, ), ),
- Notice the different hover animation duration on the icon and the label text (the animation doesn't seem to apply at all on the
icon).
Expected results
Same default foreground color hover animation duration (kThemeChangeDuration) on both the icon and the label.
Actual results
Default foreground color animation duration doesn't apply on the icon at all, only applied on the label widget which make it look buggy (see the screen recording attached).
