How to read Http response from flutter?

问题

I'm trying to read reponse from HTTP in flutter but I didnt read. I posted the request. Can anyone know, what is wrong ?

final http.Client client;

Future<http.Response> post(
  Uri uri, {
    Map<String, dynamic> postParams,
    String accessToken,
  }) async {
log.info(uri.toString());
log.info('postParams: ${postParams?.toString()}');

///Encode map to bytes
String jsonString = json.encode(postParams);
List<int> bodyBytes = utf8.encode(jsonString);

Map headers = {
  HttpHeaders.contentTypeHeader: 'application/json; charset=utf-8',
};


final response = await client
    .post(
  uri,
  body: bodyBytes,
  headers: headers,
)
    .timeout(Duration(seconds: 120));
}

You can achieve this functionality as follow

1.install http package and import it as follow

    import 'package:http/http.dart' as http;

Create an instance of http or http.Client as you did
```
final http.Client _client = http.Client();
```

Send the request to server as follow

var url = 'https://example.com/store/.....'; 

final Map<String, dynamic> data= {"name":"John Doe", "email":"johndoe@email.com"};

final Map<String, String> _headers = {
    "Content-Type": "application/json",
    "Accept": "application/json",
 };

var response = await _client.post(url, body:data, headers:_headers);

Then you can read the response as

 if(response.statusCode == 200) {
   var decoded = json.decode(response.body);
   print(decoded);

   // The Rest of code 
 }
