# processed method Null safety

List<int>? processed (

1. {bool flush: true,
2. bool end: false}

)

Get a chunk of processed data. When there are no more data available, processed will return `null`. Set `flush` to `false` for non-final calls to improve performance of some filters.

The last call to processed should have `end` set to `true`. This will make sure an 'end' packet is written on the stream.

## Implementation

    List<int>? processed({bool flush: true, bool end: false});
