# operator []= method Null safety

void operator []= (

1. int index,
2. int value

)

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.

## Implementation

    external void operator []=(int index, int value);
