Future<BackupModel?> readBackup({ required BackupModel decode(String), })

Implementation

Future<BackupModel?> readBackup({
  /// The serialization logic.
  ///
  /// The logic will vary from Model class to Model class and must be
  /// provided on each read-request.
  required BackupModel Function(String) decode,
}) async {
  print("Reading Backup...");
  try {
    final file = await _localFile;
    // Read the file
    final contents = await file.readAsString();
    print("Backup found on ${file.path}");
    return decode(contents);
  } catch (e) {
    print(_notFoundErrorMessage);
    print(e.toString());
    return null;
  }
}
