# v5 method

String v5(

1. String? namespace,
2. String? name, {
3. @Deprecated('use config instead. Removal in 5.0.0') Map<String, dynamic>? options,
4. V5Options? config,

})

Generates a namespace & name-based version 5 UUID

By default it will generate a string based on a provided uuid namespace and name, and will return a string.

The `namespace` parameter is the UUID namespace (as a String). The `name` parameter is a String that will be converted to UTF-8 bytes.

For binary data input, use v5FromBytes instead.

The first optional argument is an options map that takes various configuration options detailed in the readme. This is going to be eventually deprecated.

The second optional argument is a V5Options object that takes the same options as the options map. This is the preferred way to pass options.

Example: Generate string UUID with fully-specified options

    uuid.v5(Namespace.url.value, 'www.google.com');
    // -> "c74a196f-f19d-5ea9-bffd-a2742432fc9c"

## Implementation

    String v5(String? namespace, String? name,
        {@Deprecated('use config instead. Removal in 5.0.0')
        Map<String, dynamic>? options,
        V5Options? config}) {
      if (options != null && options.isNotEmpty) {
        V4Options? v4config;
        config = V5Options(options["randomNamespace"], v4config);
      }
      return UuidV5(goptions: goptions)
          .generate(namespace, name, options: config);
    }
