decodeSliderThemeData static method

SliderThemeData? decodeSliderThemeData(dynamic value, { bool validate = true, })

Decodes the given value to a SliderThemeData. This expects the value to have the following structure:

{
  "activeTickMarkColor": <Color>,
  "activeTrackColor": <Color>,
  "disabledActiveTickMarkColor": <Color>,
  "disabledActiveTrackColor": <Color>,
  "disabledInactiveTickMarkColor": <Color>,
  "disabledInactiveTrackColor": <Color>,
  "disabledThumbColor": <Color>,
  "inactiveTickMarkColor": <Color>,
  "inactiveTrackColor": <Color>,
  "minThumbSeparation": <double>,
  "overlappingShapeStrokeColor": <Color>,
  "overlayColor": <Color>,
  "overlayShape": <SliderComponentShape>,
  "rangeThumbShape": <RangeSliderThumbShape>,
  "rangeTickMarkShape": <RangeSliderTickMarkShape>,
  "rangeTrackShape": <RangeSliderTrackShape>,
  "rangeValueIndicatorShape": <RangeSliderValueIndicatorShape>,
  "showValueIndicator": <ShowValueIndicator>,
  "thumbColor": <Color>,
  "thumbShape": <SliderComponentShape>,
  "tickMarkShape": <SliderTickMarkShape>,
  "trackHeight": <double>,
  "trackShape": <SliderTrackShape>,
  "valueIndicatorColor": <Color>,
  "valueIndicatorShape": <SliderComponentShape>,
  "valueIndicatorTextStyle": <TextStyle>
}
