v4buffer method - Uuid class - uuid library - Dart API
Description: API docs for the v4buffer method from the Uuid class, for the Dart programming language.

# v4buffer method Null safety

List<int> v4buffer(

1. List<int> buffer,
2. {Map<String, dynamic>? options,
3. int offset = 0}

)

v4buffer() Generates a RNG version 4 UUID

By default it will generate a string based off mathRNG, and will place the result into the provided `buffer`. The `buffer` will also be returned. If you wish to have crypto-strong RNG, pass in UuidUtil.cryptoRNG.

Optionally an `offset` can be provided with a start position in the buffer.

The first argument is an options map that takes various configuration options detailed in the readme.

## Implementation

    List<int> v4buffer(
      List<int> buffer, {
      Map<String, dynamic>? options,
      int offset = 0,
    }) {
      return parse(v4(options: options), buffer: buffer, offset: offset);
    }
