operator []= method Null safety

void operator []=(
  1. int index,
  2. int value

The 32-bit two's complement integer at address + 4 * index.

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.

The address must be 4-byte aligned.
