# getBufferSubDataAsync method

Future getBufferSubDataAsync (int target, int srcByteOffset, TypedData dstData, [ int dstOffset, int length ])

## Implementation

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