# openRead method Null safety

Stream<List<int>> openRead (

1. [int? start,
2. int? end]

)

Create a new independent Stream for the contents of this file.

If `start` is present, the file will be read from byte-offset `start`. Otherwise from the beginning (index 0).

If `end` is present, only up to byte-index `end` will be read. Otherwise, until end of file.

In order to make sure that system resources are freed, the stream must be read to completion or the subscription on the stream must be cancelled.

## Implementation

    Stream<List<int>> openRead([int? start, int? end]);
