i am beginner in flutter , i started to call an api from rapid api for soccer results , it's required to add many headers to call this api , when i put these headers , i had an error in syntax
here what i have tried , nothing worked
getResults() async {
http.Response response = await http.get(
'https://api-football-v1.p.rapidapi.com/v2/fixtures/league/2',
headers: ({'x-rapidapi-key': 'e8ece1dbcdmshd1d6f778c1397c5p113b22jsn8361690f93a2'},
{'x-rapidapi-host': 'api-football-v1.p.rapidapi.com'},
{'useQueryString': true}));
I am trying to find the right syntax to make these headers works with my request
import 'package:wnetworking/wnetworking.dart';
class RapidAPI {
static const _base = 'https://api-football-v1.p.rapidapi.com/v2';
static const _apiKey = 'e8ece1dbcdmshd1d6f778c1397c5p113b22jsn8361690f93a2';
static Future<void> fetchFixturesLeague2() async {
final url = '$_base/fixtures/league/2';
print('Start fetching...');
await HttpReqService.getJson<Map<String, dynamic>>(url, headers: {
'x-rapidapi-host': 'api-football-v1.p.rapidapi.com',
'x-rapidapi-key': _apiKey,
})
.then((response) {
if (response != null) {
print('${response['api']['fixtures'].length} items');
}
})
.whenComplete(() => print('Fetching done.'));
}
}
void main(List<String> args) async {
await RapidAPI.fetchFixturesLeague2();
print('Job done!');
}
Result:
Start fetching...
380 items
Fetching done.
Job done!
Put them in a single map:
headers: (
{'x-rapidapi-key': 'e8ece1dbcdmshd1d6f778c1397c5p113b22jsn8361690f93a2',
'x-rapidapi-host': 'api-football-v1.p.rapidapi.com',
'useQueryString': true}
)

Hey I have this app where I can update status, and I use http.put method, but it takes forever to response. I got this error
error
And here is the code for http.put
Future<void> mapEventToState(
Emitter<ReportStatusState> emit, ReportStatusEvent event) async {
emit(ReportStatusLoading());
ReportStatusPut statusPut = event.statusPutBody;
// ReportStatusModel model =
// await apiAuthRepository.updateReportStatus(statusPut, event.id);
ReportStatusModel model = await updateReportStatus({'biaya': '0', 'status': 'SELESAI'}, event.id);
print(model);
if (!model.success) {
emit(ReportStatusFailure(model.message));
}
print(model.code);
emit(ReportStatusSuccess());
}}
Future<ReportStatusModel> updateReportStatus(
Map data, String id) async {
final SharedPreferencesManager sharedPreferencesManager =
locator<SharedPreferencesManager>();
String? token =
sharedPreferencesManager.getString(SharedPreferencesManager.keyAccessToken);
try {
final response = await http.put(
Uri.parse('https://api.komplekku.com/officer/api/report/v1/$id'),
body: json.encode(data),
headers: {'Authorization': 'Bearer $token'});
return ReportStatusModel.fromJson(json.decode(response.body));
} catch (e) {
throw Exception(e);
}
}
There is nothing wrong with the API, I already check using Postman and it worked perfectly fine, Anyone know what went wrong?
I am creating a flutter app using GetX, for making server connections I am using GetConnect, I successfully integrated the Get Request but I am unable to integrate Post Request
Here is the piece of code:
const _baseUrl = 'https://support.instagram.com/'; // Dummy api url and key
const Map<String, String> _mapHeaders = {
"ISG-API": "ZMWFDK83NMDF7NM5DF23FI0DBUJ"
};
class ApiService extends GetConnect {
Future<TicketReply> submitTicketReply(String ticketId, String tktreply) async {
String apiUrl = '${_baseUrl}/supportreply';
var body = {
'tktid': ticketId,
'tktreply': tktreply,
};
final response = await post(
apiUrl,
body,
headers: _mapHeaders,
);
print('response: ${response.body}');
if (response.statusCode == 200) {
return TicketReply.fromJson(response.body);
} else {
return Future.error(response.statusText!);
}
}
}
Kindly guide me how to make a successful post request using getconnect
You should add the decoder to the request like so
await post(
apiUrl,
body,
headers: _mapHeaders,
decoder: (resbody) => TicketReply.fromJson(resbody),
);
The open api request I'm trying to use requires an image binary value with content-type of multipart/form-data format.
I know you can't use dart:io in flutter web. I tried to upload an image in multipart/form-data format to the api server in flutter web while looking at several posts.
However, only a message appeared stating that the image could not be recognized.
This is the last thing I tried to create multipart types in flutter web.
import 'package:dio/dio.dart';
import 'package:http/http.dart' as http;
import 'package:flutter/material.dart';
import 'package:file_picker/file_picker.dart';
PlatformFile? objFile;
pickImage() async {
var result = await FilePicker.platform.pickFiles(
withReadStream: true,
);
setState(() {
objFile = result!.files.single;
});
uploadImage();
}
uploadImage() async {
FormData formData = FormData.fromMap({'image' : MultipartFile(test!, objFile!.size, filename: objFile!.name)});
Dio dio = new Dio();
var response = await dio.post('API url', data: formData);
}
I additionally used Multipart.form Bytes from http , Multipart.form Bytes from dio . But the result was the same.
The value checked by the request body through the postman interceptor.

When I use the MultipartFile.fromFile method used in flutter ios, I got the response normally. So I'm pretty sure there must be some mistake or misinformation in the flutter web setup.
Thanks in advance!
this is how I managed to upload an image to Laravel backend using Flutter Web
import 'dart:io';
import 'package:dio/dio.dart' as dio;
import 'package:file_picker/file_picker.dart';
Future pickupUserImage2() async {
PlatformFile? objFile;
var picked = await FilePicker.platform.pickFiles();
objFile = picked!.files.single;
String? apiUrl = Get.find<MainController>().apiUrl;
String url = '';
if (apiUrl != null) url = apiUrl + 'images';
List<int> list;
list = List<int>.from(objFile.bytes!);
dio.FormData formData = dio.FormData.fromMap({'file': dio.MultipartFile.fromBytes(list, filename: objFile.name)});
DioNetworking _dio = new DioNetworking();
dynamic result = await _dio.postData(
url,
formData,
contentType: 'multipart/form-data',
);
if (result['status'] == true) {
showToast(result['message']);
return ImageModel.Image.fromJson(result['data']);
}
}
I added a file using MultipartFile.fromBytes which has the first parameter as List which I created from this method "List.from(objFile.bytes!);"
Notes :
ImageModel.Image is a model I created to handle the image result
DioNetworking is a class that perform dio requests , I just created it to do the
authentication stuff
import 'package:dio/dio.dart';
class DioNetworking {
Dio _dio = new Dio();
Future postData(
String url,
dynamic data, {
String? contentType,
}) async {
try {
Response response = await _dio.post(url,
data: data,
options: Options(headers: {
'content-type': contentType != null ? contentType : 'application/json',
'Accept': 'application/json',
// 'Authorization': 'Bearer ${token ?? ''}'
// other headers
}));
if (response.statusCode == 200) {
dynamic data = response.data;
return data;
} else {
print(response.statusCode);
}
} on DioError catch (e) {
print(e);
if (e.type == DioErrorType.connectTimeout) {
return {'status': 'Connect Timed Out'};
}
if (e.type == DioErrorType.receiveTimeout) {
return {'status': 'Receive Timed Out'};
}
if (e.type == DioErrorType.response) {
print(e.response!.data);
print(e.response!.headers);
}
}
}
}
I have declared a class to make api requests using flutter Dio as follows.
class DioUtil {
static Dio _instance;
static Dio getInstance() {
if (_instance == null) {
_instance = createDio();
}
return _instance;
}
static Dio createDio() {
var dio = Dio();
dio.interceptors.add(InterceptorsWrapper(onRequest: (options, handler) {
// Do something before request is sent
return handler.next(options); //continue
}, onResponse: (response, handler) {
// Do something with response data
return handler.next(response); // continue
}, onError: (DioError e, handler) async {
if (e.response != null) {
if (e.response.statusCode == 401) {
var dio = DioUtil.getInstance();
dio.interceptors.requestLock.lock();
dio.interceptors.responseLock.lock();
RequestOptions requestOptions = e.requestOptions;
await refreshToken();
Repository repository = Repository();
var accessToken = await repository.readData("accessToken");
final opts = new Options(
method: requestOptions.method
);
dio.options.headers["Authorization"] = "Bearer " + accessToken;
dio.interceptors.requestLock.unlock();
dio.interceptors.responseLock.unlock();
dio.request(requestOptions.path,
options: opts,
data: requestOptions.data,
queryParameters: requestOptions.queryParameters);
}//TODO: handle else clause
}
}));
return dio;
}
static refreshToken() async {
Response response;
Repository repository = Repository();
var dio = Dio();
final Uri apiUrl = Uri.parse(BASE_PATH + "auth/reIssueAccessToken");
var refreshToken = await repository.readData("refreshToken");
dio.options.headers["Authorization"] = "Bearer " + refreshToken;
response = await dio.postUri(apiUrl);
if (response.statusCode == 200) {
LoginResponse loginResponse =
LoginResponse.fromJson(jsonDecode(response.toString()));
repository.addValue('accessToken', loginResponse.data.accessToken);
repository.addValue('refreshToken', loginResponse.data.refreshToken);
} else {
print(response.toString());
}
}
}
and I use flutter bloc pattern and my bloc is as follows.
class OurClassBloc extends Bloc<OurClassEvent, OurClassState> {
OurClassBloc(OurClassState initialState) : super(initialState);
Repository repository = Repository();
#override
Stream<OurClassState> mapEventToState(
OurClassEvent event,
) async* {
if (event is GetClasses) {
yield* _getClassCategories(event);
}
}
Stream<OurClassState> _getClassCategories(GetClasses event) async* {
Response response;
var dio = DioUtil.getInstance();
final String apiUrl = (BASE_PATH + "classCategories");
var accessToken = await repository.readData("accessToken");
Map<String, dynamic> map = {"active": event.active};
dio.options.headers["Authorization"] = "Bearer " + accessToken;
dio.options.headers["Accept"] = "*/*";
try {
response = await dio.get(apiUrl, queryParameters: map);
if (response.statusCode == 200) {
OurClassResponse loginResponse =
OurClassResponse.fromJson(jsonDecode(response.toString()));
yield OurClassSuccess(loginResponse);
}
if (response.statusCode >= 400) {
yield OurClassFailed();
}
} catch (e) {
yield OurClassFailed();
}
}
}
When I make the requests with valid access token, I get 200 status code in bloc class and api works fine.when the token is expired, the dio class correctly gets the new token, make the same api call with new token successfully and inside the below callback I get the correct response also.
onResponse: (response, handler) {
return handler.next(response);
}
but response doesn't comes to bloc class. Though it returned the response by calling return handler.next(response);,it is not coming to response variable inside _getClassCategories method.I expect the correct response should come to the response variable in bloc class for both scenarios:
makes the api call with valid token.
makes the api call with expired token.
but only scenario 1 is working in my code and hope someone here can help me to fix this.
EDIT- this works fine with dio previous version(3.0.10) - code
dio.request(requestOptions.path,
options: opts,
data: requestOptions.data,
queryParameters: requestOptions.queryParameters);
This line creates a new request with no relation to the original one. If the request succeeds, there is no code listening for a response. If you want the original caller to receive anything, you will need to forward the response to the original handler:
try {
final response = await dio.request(requestOptions.path,
options: opts,
data: requestOptions.data,
queryParameters: requestOptions.queryParameters);
handler.resolve(response);
} on DioError catch (error) {
handler.next(error); // or handler.reject(error);
}
Also, be sure to forward the error to the handler in non-401 cases as well. Dio 4.0.0 interceptors don't automatically forward anything.
I am working in Flutter App to get the items from API. I want to cache the API response for 12 hours. Every 12 hours the response will be changed. Once the 12 hours completed then I need to fetch it from Internet. I used the below code to get it from internet.
Future<List<Playlist>> fetchPlaylistByChannelId({String channelId}) async {
Map<String, String> parameters = {
'part': 'snippet,contentDetails',
'channelId': channelId,
'maxResults': '10',
'key': API_KEY,
};
Uri uri = Uri.https(
_baseUrl,
'/youtube/v3/playlists',
parameters,
);
Map<String, String> headers = {
HttpHeaders.contentTypeHeader: 'application/json',
};
// Get Playlist details
var response = await http.get(uri, headers: headers);
if (response.statusCode == 200) {
var data = json.decode(response.body);
List<dynamic> playListJson = data['items'];
// Fetch all play list
List<Playlist> playLists = [];
playListJson.forEach(
(json) => playLists.add(
Playlist.fromMap(
json["id"],
json["snippet"],
json["contentDetails"],
),
),
);
return playLists;
} else {
throw json.decode(response.body)['error']['message'];
} }
Please help me out this.
Include flutter_cache_manager in pubspec.yaml.
Now define a cache manager
import 'package:flutter_cache_manager/flutter_cache_manager.dart';
import 'package:http/http.dart' as http;
import 'dart:io';
import 'package:path_provider/path_provider.dart';
import 'package:path/path.dart' as path;
// Custom Implementation of CacheManager
// by extending the BaseCacheManager abstract class
class MyCacheManager extends BaseCacheManager {
static const key = "customCache";
static MyCacheManager _instance;
// singleton implementation
// for the custom cache manager
factory MyCacheManager() {
if (_instance == null) {
_instance = new MyCacheManager._();
}
return _instance;
}
// pass the default setting values to the base class
// link the custom handler to handle HTTP calls
// via the custom cache manager
MyCacheManager._()
: super(key,
maxAgeCacheObject: Duration(hours: 12),
maxNrOfCacheObjects: 200,
fileFetcher: _myHttpGetter);
#override
Future<String> getFilePath() async {
var directory = await getTemporaryDirectory();
return path.join(directory.path, key);
}
static Future<FileFetcherResponse> _myHttpGetter(String url,
{Map<String, String> headers}) async {
HttpFileFetcherResponse response;
// Do things with headers, the url or whatever.
try {
var res = await http.get(url, headers: headers);
// add a custom response header
// to regulate the caching time
// when the server doesn't provide cache-control
res.headers.addAll({'cache-control': 'private, max-age=120'});
response = HttpFileFetcherResponse(res);
} on SocketException {
print('No internet connection');
}
return response;
}
}
Now use
class HttpProvider {
Future<Response> getData(String url, Map<String, String> headers) async {
var file = await MyCacheManager().getSingleFile(url, headers: headers);
if (file != null && await file.exists()) {
var res = await file.readAsString();
return Response(res, 200);
}
return Response(null, 404);
}
}

UPDATE: flutter_cache_manager 2.0.0
There is no longer a need to extend on BaseCacheManager, you can directly call the constructor. The BaseCacheManager is now only an interface. CacheManager is the implementation you can use directly.

Another way of caching is by using hive a No-SQL database it is faster to retrieve documents and is easy to use. And when users come online just refresh the data in hive
For more details check:https://github.com/shashiben/Anime-details to know how to cache using hive
