fromDynamic static method

NumberValidator fromDynamic(
  1. dynamic map
)

Processes the validator object from the given map which must be an actual Map or a Map-like object that supports the [] operator. Any non-null object that is not Map-like will result in an error. A null value will result in a return value of null.

This expects the JSON format:

{
  "allowDecimal": <bool>
  "type": "number"
}

Implementation

static NumberValidator fromDynamic(dynamic map) {
  NumberValidator result;

  if (map == null) {
    throw Exception('[NumberValidator.fromDynamic]: map is null');
  } else {
    assert(map['type'] == kType);

    result = NumberValidator(
      allowDecimal: JsonClass.parseBool(
        map['allowDecimal'],
        whenNull: true,
      ),
    );
  }

  return result;
}
