I Want to get the token from my API by Dio flutter? - flutter

Question

I'm trying to get my token from the API but it's empty
This is dio functions
import 'package:dio/dio.dart';
class DioHelper
{
static Dio dio;
static init()
{
print('dioHelper Initialized');
dio = Dio(
BaseOptions(
baseUrl:'my api link',
receiveDataWhenStatusError: true,
));
}
static Future<Response> getData ({
String url,
Map<String,dynamic> query,
String lang = 'en',
String token,
Map<String,dynamic> data,
})async
{
dio.options.headers =
{
'lang':'$lang',
'Content-Type':'application/json',
'Authorization' : '$token'
};
return await dio.get(
url,
queryParameters: query
);
}
static Future<Response> postData ({
String url,
Map<String,dynamic> query,
Map<String,dynamic> data,
String lang = 'ar',
String token
})async
{
dio.options.headers =
{
'lang':'$lang',
'Content-Type':'application/json',
'Authorization' : '$token'
};
return await dio.post(
url,
queryParameters: query,
data: data,
);
}
static Future<Response> putData ({
String url,
Map<String,dynamic> query,
Map<String,dynamic> data,
String lang = 'ar',
String token
})async
{
dio.options.headers =
{
'lang':'$lang',
'Content-Type':'application/json',
'Authorization' : '$token'
};
return await dio.put(
url,
queryParameters: query,
data: data,
);
}
static Future<Response> deleteData ({
String url,
String lang = 'ar',
String token
})async
{
dio.options.headers =
{
'lang':'$lang',
'Content-Type':'application/json',
'Authorization' : '$token'
};
return await dio.delete(url);
}
}
and pass value in this variable
String token = '';
and fuctions sharedPreferences
import 'package:shared_preferences/shared_preferences.dart';
class CacheHelper
{
static SharedPreferences sharedPreferences;
static init () async {
sharedPreferences = await SharedPreferences.getInstance();
}
static dynamic getData(String key, ){
return sharedPreferences.get(key);
}
static Future<bool> saveData({ String key, dynamic value})async{
if(value is String) return await sharedPreferences.setString(key, value);
if(value is int) return await sharedPreferences.setInt(key, value);
if(value is bool) return await sharedPreferences.setBool(key, value);
return await sharedPreferences.setDouble(key, value);
}
static Future<bool> removeData (String key)async{
return await sharedPreferences.remove(key);
}
}
*CALL THE TOKEN*
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
Bloc.observer = MyBlocObserver();
await DioHelper.init();
await CacheHelper.init();
token = CacheHelper.getData('token');
var IsLogin = CacheHelper.getData( 'IsLogin');
var IsBoarding = CacheHelper.getData( 'IsBoarding');
print(IsLogin);
print(IsBoarding);
print(token);
var widget;
if (IsBoarding != null) {
if (token == null) {
widget = ShopingScreen();
} else {
widget = Login_Screen();
}
} else {
widget = BordScreen();
}
THANKS
Is there any solution
I described my problem a few days ago, but without details, there was no useful solution
Tried a lot but it didn't solve this problem. I tried wiping the phone data or reformatting the codes and restarting the device several times.
