createReadStream method

@override Stream createReadStream()

Return file contents as readonly stream. Caller should dispose stream when complete.

Implementation

@override
Stream<dynamic> createReadStream() {
  // For VM platforms
  final ioFile = _ioFile;
  if (ioFile != null) {
    return ioFile.openRead();
  }

  // For web platforms, we need to read the entire file and emit it
  // as a stream. This is less efficient than a true stream, but works
  // cross-platform.
  return Stream.fromFuture(_file.readAsBytes())
      .map((bytes) => bytes as dynamic);
}
