peekNextBuildNumber method

Future<String> peekNextBuildNumber(String environment, { String? baseDir, })

Peeks at what the next build number will be without modifying the state.

Returns a 3-digit zero-padded string (e.g., '001').

Implementation

Future<String> peekNextBuildNumber(String environment, {String? baseDir}) async {
  final dirPath = baseDir != null ? '$baseDir/$_stateDir' : _stateDir;
  final filePath = '$dirPath/$_stateFile';

  final file = File(filePath);
  if (!file.existsSync()) {
    return '001';
  }

  try {
    final contentBytes = file.readAsBytesSync();
    String contentString = contentBytes.isEmpty ? '{}' : utf8.decode(contentBytes);

    Map<String, dynamic> jsonMap;
    try {
      jsonMap = json.decode(contentString);
    } catch (_) {
      jsonMap = {};
    }

    final state = BuildStateModel.fromJson(jsonMap);
    final today = DateFormat('yyyyMMdd').format(DateTime.now());

    if (state.lastDate == today) {
      final currentCounter = state.counters[environment] ?? 0;
      return (currentCounter + 1).toString().padLeft(3, '0');
    } else {
      return '001';
    }
  } catch (e) {
    return '001'; // Fallback safely
  }
}
