fromDynamic static method

MinNumberValidator 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:

{
  "number": <number>,
  "type": "min_number"
}

Implementation

static MinNumberValidator fromDynamic(dynamic map) {
  MinNumberValidator result;

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

    result = MinNumberValidator(
      number: JsonClass.maybeParseDouble(
            map['number'],
          ) ??
          0,
    );
  }

  return result;
}
