readDoc function

Future<File?> readDoc(
  1. String name, {
  2. int? cacheSize,
})

Implementation

Future<File?> readDoc(String name, {int? cacheSize}) async {
  //TODO: support reading images/file from indexedDb or something for web

  final file = (await localFile(name, "jaman"));
  // ignore: unused_local_variable
  final err = (name == Options().no_image_placeholder_name)
      ? NoImagePlaceholderException()
      : Exception("file $file doesnt exist");
  if (!file.existsSync())
    // throw err;
    return null;
  if (file.lengthSync() < 5) throw Exception("file $file definitely to small");
  //TO-DO: was wenn keine datei da lesbar ist? -> return null
  // das ist wichtig damit der placeholder statt einem "image corrupt" dargestellt wird
  return await localFile(name);
