}) async {
  final file = File(path);
  if (!await file.exists()) return false;
  try {
    final content = await file.readAsString();
    final map = json.decode(content) as Map<String, dynamic>;
    for (final entry in map.entries) {
      _store[scope]![entry.key] = entry.value;
      _sources[scope]![entry.key] = ConfigSource.file;
    }
    return true;
  } catch (_) {
