decodeLineStyleSpec static method

LineStyleSpec? decodeLineStyleSpec(
  1. dynamic map, {
  2. bool validate = true,
})

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

{
  "color": <Color>,
  "dashPattern": <List<int>>,
  "thickness": <int>
}

Implementation

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

  if (result is charts.LineStyleSpec) {
    result = map;
  } else if (map != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/line_style_spec',
      value: map,
      validate: validate,
    ));
    result = charts.LineStyleSpec(
      color: decodeColor(map['color'], validate: false),
      dashPattern: map['dashPattern'] == null
          ? null
          : List<int>.from(
              map['dashPattern'].map((e) => JsonClass.parseInt(e)!),
            ),
      thickness: JsonClass.parseInt(map['thickness']),
    );
  }

  return result;
