decodeSliderStyle static method

SliderStyle? decodeSliderStyle(dynamic map, { bool validate = true, })

Decodes the object from a Map-like dynamic structure. This expects the JSON format to be of the following structure:

{
  "fillColor": <Color>,
  "handleOffset": <Point>,
  "handlePosition": <SliderHandlePosition>,
  "handleSize": <Rectangle>,
  "strokeColor": <Color>,
}

Implementation

static charts.SliderStyle? decodeSliderStyle(
  dynamic map, {
  bool validate = true,
}) {
  charts.SliderStyle? result;

  if (map is charts.SliderStyle) {
    result = map;
  } else if (map != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/slider_style',
      value: map,
      validate: validate,
    ));
    result = charts.SliderStyle(
      fillColor: decodeColor(
        map['fillColor'],
        validate: false,
      ),
      handleOffset: map['point'] == null
          ? const Point<double>(0, 0)
          : Point<double>(
              JsonClass.parseDouble(map['point']['x'])!,
              JsonClass.parseDouble(map['point']['y'])!,
            ),
      handlePosition: decodeSliderHandlePosition(
            map['handlePosition'],
            validate: false,
          ) ??
          common.SliderHandlePosition.middle,
      handleSize: map['handleSize'] == null
          ? const Rectangle(0, 0, 10, 20)
          : Rectangle(
