# getBufferSubDataAsync method Null safety

Future getBufferSubDataAsync (

1. int target,
2. int srcByteOffset,
3. TypedData dstData,
4. [int? dstOffset,
5. int? length]

)

## Implementation

    Future getBufferSubDataAsync(int target, int srcByteOffset, TypedData dstData,
            [int? dstOffset, int? length]) =>
        promiseToFuture(JS("", "#.getBufferSubDataAsync(#, #, #, #, #)", this,
            target, srcByteOffset, dstData, dstOffset, length));
