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