fluro路由传参时需要解析到地址上

dart
  static String  mapToQuery (Map data){
    String query =  "";
    if (data != null) {
      int index = 0;
      for (dynamic key in data.keys) {
        dynamic value = Uri.encodeComponent(data[key]+"");
        if (index == 0) {
          query = "?";
        } else {
          query = query + "\&";
        }
        query += "$key=$value";
        index++;
      }
    }
    return query;
  }
