@override String? read(String filename)

Implementation

@override
String? read(String filename) {
  var fileIndex = index[filename];
  if (fileIndex != null) {
    if (fileIndex.link != null) {
      return read(fileIndex.link!);
    } else {
      return utf8.decode(bytes.buffer.asUint8List(
          fileIndex.offset! + contentOffset + bytes.offsetInBytes,
          fileIndex.size!));
    }
  }
  return null;
}
