dart:typed_data
Int64List class
A fixed-length list of 64-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 64 bits, interpreted as a signed 64-bit two's complement integer with values in the range -9223372036854775808 to +9223372036854775807.

Constructors
- Int64List(int length)
factory
- Creates an Int64List of the specified length (in elements), all of whose elements are initially zero.
- Int64List.fromList(List<int> elements)
factory
- Creates a Int64List with the same length as the
elements list and copies over the elements. [...] - Int64List.view(ByteBuffer buffer, [ int offsetInBytes = 0, int length ])
factory
- Creates an Int64List view of the specified region in
buffer. [...]
