loadFromStorage static method

Future<SimpleOpfsFileSystem> loadFromStorage(
  1. String path, {
  2. String vfsName = 'simple-opfs',
  3. bool readWriteUnsafe = false,
})

Loads an SimpleOpfsFileSystem in the desired path under the root directory for OPFS as given by navigator.storage.getDirectory() in JavaScript.

Throws a VfsException if OPFS is not available - please note that this file system implementation requires a recent browser and only works in dedicated web workers.

When readWriteUnsafe is passed, the synchronous file handles are opened using the proposed lock mode. This mode is currently not supported across browsers, but can be used on Chrome for faster database access across tabs.

Implementation

static Future<SimpleOpfsFileSystem> loadFromStorage(
  String path, {
  String vfsName = 'simple-opfs',
  bool readWriteUnsafe = false,
}) async {
  final storage = storageManager;
  if (storage == null) {
    throw VfsException(SqlError.SQLITE_ERROR);
  }

  final (_, directory) = await _resolveDir(path);
  return inDirectory(directory,
      vfsName: vfsName, readWriteUnsafe: readWriteUnsafe);
}
