dart:typed_data library
Lists that efficiently handle fixed sized data (for example, unsigned 8 byte integers) and SIMD numeric types.
To use this library in your code:
import 'dart:typed_data';
Classes
 ByteBuffer
 A sequence of bytes underlying a typed data object.
 ByteData
 A fixedlength, randomaccess sequence of bytes that also provides random and unaligned access to the fixedwidth integers and floating point numbers represented by those bytes.
 BytesBuilder
 Builds a list of bytes, allowing bytes and lists of bytes to be added at the end.
 Endian
 Endianness of number representation.
 Float32List
 A fixedlength list of IEEE 754 singleprecision binary floatingpoint numbers that is viewable as a TypedData.
 Float32x4
 Float32x4 immutable value type and operations.
 Float32x4List
 A fixedlength list of Float32x4 numbers that is viewable as a TypedData.
 Float64List
 A fixedlength list of IEEE 754 doubleprecision binary floatingpoint numbers that is viewable as a TypedData.
 Float64x2
 Float64x2 immutable value type and operations.
 Float64x2List
 A fixedlength list of Float64x2 numbers that is viewable as a TypedData.
 Int16List
 A fixedlength list of 16bit signed integers that is viewable as a TypedData.
 Int32List
 A fixedlength list of 32bit signed integers that is viewable as a TypedData.
 Int32x4
 Int32x4 and operations.
 Int32x4List
 A fixedlength list of Int32x4 numbers that is viewable as a TypedData.
 Int64List
