@override Future<Map<String, dynamic>?> readCredentials()

Implementation

@override
Future<Map<String, dynamic>?> readCredentials() async {
  final file = File(credentialsFile);
  if (await file.exists()) {
    try {
      return json.decode(await file.readAsString()) as Map<String, dynamic>;
    } catch (_) {
      // Corrupt/unreadable credentials file -> treat as "not logged in"
      // rather than crashing the CLI.
      return null;
    }
  }
  return null;
}
