List data;
i want to show response but when i try to assign jasonResponse to data i get this error
[ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: type 'List' is not a subtype of type 'Map'
so what should i do
how to assign array of object to data
Future<String> getJsonData() async{
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
Map data = {'sale_id': sharedPreferences.getInt("token")};
var jsonResponse;
var response = await http.post(
"http://",
body: json.encode(data),
headers: {
"Content-Type": "application/json"
},
);
if (response.statusCode == 200) {
jsonResponse = json.decode(response.body);
print('jsonRespnse');
print(jsonResponse['developer_list']);
if (jsonResponse != null) {
setState(() {
data = jsonResponse['developer_list'];
});
Your data
is a type Map
but you are assigning a type List
.
Simply, add a key with your value, like below:
data['developer_list'] = jsonResponse['developer_list'];
Make sure to access that list by data['developer_list']
