    Please make sure that map["data"] is a type of <String, dynamic>.
    The error says that you are parsing string to a type of <String, dynamic>.

    As per the error you are getting, it seems like map['data'] is of type String.

    You need to convert it to JSON format Map<STring,dynamic> before passing it to MatchData.fromJson()

    MatchData.fromJson requires a String. It might work to do:

        MatchData dd = MatchData.fromJson(json.encode(map['data']));

    But good chance that your MatchData class also has a fromMap method. Then you can use

        MatchData dd = MatchData.fromMap(map['data']);
