How I can get specific value from HTTP method in FLUTTER?-CodePudding

My output is like this:

{
"scope": [],
"_id": "62413827f85e740dd8af749d",
"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJpc3N1ZXIiLCJzdWIiOnsidXNlcklkIjoiNjI0MTM4MjdmODVlNzQwZGQ4YWY3NDlhIn0sImlhdCI6MTY0ODQ0MTM4M30.cNE32yojMlbohsOtgB2docCsZk8UPqEbPVTizV--rMs",
"user": {
    "_id": "62413827f85e740dd8af749a",
    "email": "[email protected]",
    "password": "hello",

}

How can I get the value of "email" from "user" in flutter? I am using the following code.

http
      .post(Uri.parse(url),
          headers: {"Content-type": "application/json;charset=UTF-8"},
          body: jsonEncode(model))
      .then((value) {
    var access = jsonDecode(value.body);

CodePudding user response：

first you should use model . without using model it will help you

it's only a example how to get value from map

  dynamic apiResp = {
    "scope": [],
    "_id": "62413827f85e740dd8af749d",
    "access_token":
        "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJpc3N1ZXIiLCJzdWIiOnsidXNlcklkIjoiNjI0MTM4MjdmODVlNzQwZGQ4YWY3NDlhIn0sImlhdCI6MTY0ODQ0MTM4M30.cNE32yojMlbohsOtgB2docCsZk8UPqEbPVTizV--rMs",
    "user": {
      "_id": "62413827f85e740dd8af749a",
      "email": "[email protected]",
      "password": "hello",
      "phone": "01723456789",
      "createdAt": "2022-03-28T04:23:03.334Z",
      "updatedAt": "2022-03-28T04:23:03.334Z",
      "__v": 0
    },
    "createdAt": "2022-03-28T04:23:03.348Z",
    "updatedAt": "2022-03-28T04:23:03.348Z",
    "__v": 0
  };

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('${apiResp['user']['email']}')),
