slice method

Buffer slice([
  1. int offset = 0,
  2. int? length
])

Creates a new Buffer from a region of this buffer.

Items are copied from the range [offset : offset+length]. If length is omitted, the range extends to the end of the buffer.

The range must satisy the relations 0 ≤ offset ≤ offset+length ≤ this.length.

final Buffer buffer = Buffer.fromList([1, 2, 3, 4, 5, 6, 7, 8]);
final Buffer newBuffer = buffer.slice(4);
print(buffer);    // [1, 2, 3, 4, 5, 6, 7, 8]
print(newBuffer); // [5, 6, 7, 8]

Implementation

Buffer slice([final int offset = 0, final int? length]) {
  final int? end = length != null ? offset + length : null;
  return Buffer.fromList(_data.sublist(offset, end));
}
