## Detailed Description

A byte buffer holding `UInt8`, `SInt32`, `SInt64`, or `Float64` values, used with `FlutterStandardMessageCodec` and `FlutterStandardMethodCodec`.

Two's complement encoding is used for signed integers. IEEE754 double-precision representation is used for floats. The platform's native endianness is assumed.
