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.

factory
Uint8List.fromList(List<int> elements)

Creates a Uint8List with the same length as the elements list and copies over the elements.

factory
Uint8List.view(ByteBuffer buffer, [ int offsetInBytes = 0, int length ])

Creates a Uint8List view of the specified region in buffer.
