# Uint8List class

A fixed-length list of 8-bit unsigned integers.

For long lists, this implementation can be considerably more space- and time-efficient than the default List implementation.

Integers stored in the list are truncated to their low eight bits, interpreted as an unsigned 8-bit integer with values in the range 0 to 255.

## Constructors

Uint8List(int length)
  Creates a Uint8List of the specified length (in elements), all of whose elements are initially zero.
