Scrollbar.thickness property is ignored when the Scrollbar is hovered #143881
Description
Steps to reproduce
- Set a thickness on scrollbar to something other than the default
- Hover the scrollbar
- Scrollbar will use thickness from Scrollbar theme when hovered instead of thickness manually set on scrollbar
Expected results
Scrollbar should not ignore manually set thickness on hover
Actual results
Scrollbar ignores manual thickness on hover
MaterialStateProperty<double> get _thickness {
return MaterialStateProperty.resolveWith((Set<MaterialState> states) {
if (states.contains(MaterialState.hovered) && _trackVisibility.resolve(states)) {
return _scrollbarTheme.thickness?.resolve(states)
?? _kScrollbarThicknessWithTrack;
}
// The default scrollbar thickness is smaller on mobile.
return widget.thickness
?? _scrollbarTheme.thickness?.resolve(states)
?? (_kScrollbarThickness / (_useAndroidScrollbar ? 2 : 1));
});
}should be changed to
MaterialStateProperty<double> get _thickness {
if(widget.thickness != null) {
return widget.thickness;
}
return MaterialStateProperty.resolveWith((Set<MaterialState> states) {
if (states.contains(MaterialState.hovered) && _trackVisibility.resolve(states)) {
return _scrollbarTheme.thickness?.resolve(states)
?? _kScrollbarThicknessWithTrack;
}
// The default scrollbar thickness is smaller on mobile.
return _scrollbarTheme.thickness?.resolve(states)
?? (_kScrollbarThickness / (_useAndroidScrollbar ? 2 : 1));
});
