A fixed-length list of 32-bit signed integers that is viewable as a TypedData.

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 32 bits, interpreted as a signed 32-bit two's complement integer with values in the range -2147483648 to 2147483647.

Constructors

Int32List(int length)

Creates an Int32List of the specified length (in elements), all of whose elements are initially zero.

factory
Int32List.fromList(List<int> elements)

Creates a Int32List with the same length as the elements list and copies over the elements.

factory
Int32List.view(ByteBuffer buffer, [ int offsetInBytes = 0, int length ])

Creates an Int32List view of the specified region in buffer.
