Implementation

@override
Iterable<String> format(int level, dynamic message) {
  final header =
      '[${DateTime.now().toUtc().toIso8601String()}] [${SquadronLogLevel.getName(level)}] [${Squadron.id}]';
  if (message is Iterable) {
    message = message
        .map((m) => m?.toString() ?? '')
        .expand((m) => m.toString().split('\n'));
  } else {
    message = message?.toString().split('\n') ?? const [];
  }
  return message.where((m) => m.isNotEmpty).map((line) => '$header $line');
