当它不活动时，我们如何改变滑块圆形图标的颜色？当它在进行中时，我可以看到改变它的属性，但是当我点击停止歌曲并恢复正常时，它变为灰色。我没有在任何地方设置灰色，不确定如何更改该颜色。我附上了它停止和播放歌曲时的屏幕截图。
Widget slider1() {
return SliderTheme(

.toDouble(),
onChangeStart: (double value) {
print('Start value is ' + value.toString());
},
onChangeEnd: (double value) {
print('Finish value is ' + value.toString());
},
onChanged: (double value) {
setState(() {
if (value == position.inSeconds) {
} else {
seekToSecond(value.toInt());
value = value;
}
});
}),
);
}
