v4 method Null safety
v4() Generates a RNG version 4 UUID
By default it will generate a string based mathRNG, and will return a string. If you wish to use crypto-strong RNG, pass in UuidUtil.cryptoRNG
The first argument is an options map that takes various configuration options detailed in the readme.
Implementation
String v4({Map<String, dynamic>? options}) {
return _uuidv4.generate(options: options);
}
