exists property

@override bool get exists

True if resource exists in the underlying storage system.

Implementation

@override
bool get exists {
  // On VM platforms, use the IO file if available
  final ioFile = _ioFile;
  if (ioFile != null) {
    return ioFile.existsSync();
  }

  // On web, XFile.length returns a future, so we can't easily check existence
  // synchronously. We assume the file exists if we have an XFile instance.
  return true;
}
