# v1buffer method Null safety

List<int> v1buffer(

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

)

v1buffer() Generates a time-based version 1 UUID

By default it will generate a string based off current time, and will place the result into the provided `buffer`. The `buffer` will also be returned..

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> v1buffer(
      List<int> buffer, {
      Map<String, dynamic>? options,
      int offset = 0,
    }) {
      return parse(v1(options: options), buffer: buffer, offset: offset);
    }
