fromDynamic static method
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:
{
"type": "email"
}
Implementation
static EmailValidator fromDynamic(dynamic map) {
EmailValidator result;
if (map == null) {
throw Exception('[EmailValidator.fromDynamic]: map is null');
} else {
assert(map['type'] == kType);
result = const EmailValidator();
}
return result;
}
