      "password": "password",
      "confirm": "password",

      "customer_group_id": 1,
      "agree": 1,
      "custom_field": {
        "account": {
          "1": " 364545454"
        }
      }
    }

and my problem is how to pass this section.

    "custom_field": {
        "account": {
          "1": " 364545454"
        }

Map<Strng,dynamic>` data = 

    {

    type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'String' in type cast

Encode your data and follow the convention

var response = await _dio.post("$url",
          options: header, data: jsonEncode(data));

          "1": " 364545454"
        }
      })
    }

CodePudding user response：

You can pass like that :

  var data = {}; 

  data["firstname"] = "Demo";
  data["lastname"] = "User";
  data["email"] = "[email protected]";
  data["password"] ="password";

and pass like this

 var response = await _dio.post($url,
           data: jsonEncode(data));
