decodeAnnotationLabelAnchor static method

AnnotationLabelAnchor? decodeAnnotationLabelAnchor(
  1. dynamic map, {
  2. bool validate = true,
})

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

  • end
  • middle
  • start

Implementation

static common.AnnotationLabelAnchor? decodeAnnotationLabelAnchor(
  dynamic map, {
  bool validate = true,
}) {
  common.AnnotationLabelAnchor? result;

  if (map is common.AnnotationLabelAnchor) {
    result = map;
  } else if (map != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/annotation_label_anchor',
      value: map,
      validate: validate,
    ));
    switch (map) {
      case 'end':
        result = common.AnnotationLabelAnchor.end;
        break;

      case 'middle':
        result = common.AnnotationLabelAnchor.middle;
        break;

      case 'start':
        result = common.AnnotationLabelAnchor.start;
        break;

      default:
        throw Exception(
          '[decodeAnnotationLabelAnchor]: unknown value: [$map]',
        );
    }
  }

  return result;
}
