int operator [] (
  1. int index

The 32 or 64-bit two's complement integer at address + (4 or 8) * index.

On 32-bit platforms this is a 32-bit integer, and on 64-bit platforms this is a 64-bit integer.

On 32-bit platforms a Dart integer is truncated to 32 bits (as if by .toSigned(32)) before being stored, and the 32-bit value is sign-extended when it is loaded.

On 32-bit platforms the address must be 4-byte aligned, and on 64-bit platforms the address must be 8-byte aligned.
