decodeFillPatternType static method

FillPatternType? decodeFillPatternType(
  1. dynamic map, {
  2. bool validate = true,
})

Expects the map to be either a charts.FillPatternType or a String containing one of the following values:

  • forwardHatch
  • solid

Implementation

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

  if (map is charts.FillPatternType) {
    result = map;
  } else if (map != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/fill_pattern_type',
      value: map,
      validate: validate,
    ));
    switch (map) {
      case 'forwardHatch':
        result = charts.FillPatternType.forwardHatch;
        break;

      case 'solid':
        result = charts.FillPatternType.solid;
        break;

      default:
        throw Exception('Unknown [FillPatternType] encountered: [$map]');
    }
  }

  return result;
}
