How can I change color of scroll bar indicator in SingleChildScrollView, the SingleChildScrollView doesn’t have option color or something for style, if we can’t change color of SingleChildScrollView do we have any alternative for that

RawScrollbar(
    thumbColor: Colors.red,
    radius: Radius.circular(16),
    thickness: 7,
    child: SingleChildScrollView()
)
