validate method

  1. @override
bool validate(
  1. dynamic value, [
  2. List<String>? options
])
override

Validates whether the provided value is a valid UUID.

A UUID is a 128-bit number used to uniquely identify information in computer systems. This method uses a regular expression to check if the value matches the standard UUID format.

The value parameter is the value to be validated. It can be of any type. The options parameter is an optional list of strings that can be used to provide additional options for validation.

Returns true if the value is a valid UUID, otherwise returns false.

Implementation

@override
bool validate(dynamic value, [List<String>? options]) {
  if (value == null) return false;
  return RegExp(
    r'^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$',
  ).hasMatch(value.toString());
}
