Are JsonDecode() and JsonEncoder() has a try option?

[SittiphanSittisak]

This option work like int.tryParse() that will return int?.

Where are these?

  JsonDecoder().tryConvert(data);
  JsonEncoder().tryConvert(data);

I can create this by

class Json {
  static String? tryEncode(data) {
    try {
      return jsonEncode(data);
    } catch (e) {
      return null;
    }
  }

  static dynamic tryDecode(data) {
    try {
      return jsonDecode(data);
    } catch (e) {
      return null;
    }
  }
}

void main() {
  String? jsonEncode = Json.tryEncode(dataEncoded);
  dynamic jsonDecode = Json.tryDecode(dataDecoded);
  print("jsonEncode: $jsonEncode");
  print("jsonDecode: $jsonDecode");
}

However, I'm uncomfortable with this.
Is it impossible to add this function?
