List<int> extractByteRange(Uint8List pdfBytes)

Extracts the last /ByteRange array from pdfBytes.

Implementation

  if (useInternalByteRangeParser) {
    return _extractByteRangeInternal(pdfBytes);
  }

        return range;
      }
    } catch (e) {
      if (e is StateError && e.message == 'ByteRange not found') {
        throw e;
      }
    }
  }

      return range;
    }
  } catch (_) {

  }

  final range = _extractByteRangeInternal(pdfBytes);
