I am trying to implement the auto logout feature after x mins of inactivity on flutter while using Firebase , authentication method being email.
I have searched online but whatever I've found is not for flutter.
Any help will be greatly appreciated thank you!
you can use interceptor for all api instance like this, but instead customize the onRequest method.
the idea is: save time information when hit api occurred. and then whenever another hit api occur, check duration between now and last saved time.
if the duration is longer than, let's say 5 minutes, then you can call method logout, else you can continue the request
here some snippet to make it clear:
Future<Dio> getApiClient() async {
_dio.interceptors.clear();
_dio.interceptors
.add(InterceptorsWrapper(onRequest: (RequestOptions options) {
// Do something before request is sent
var pref = await SharedPreferences.getInstance();
var timeNow = DateTime.now().millisecondsSinceEpoch;
var lastHitApi = pref.getInt(LAST_HIT_API);
var delay = timeNow - lastHitApi;
pref.setInt(LAST_HIT_API, timeNow);
if (delay > DELAY_MAX) {
// do logout here
}
return options;
},onResponse:(Response response) {
// Do something with response data
return response; // continue
}, onError: (DioError error) async {
// Do something with response error
}));
_dio.options.baseUrl = baseUrl;
return _dio;
}
Edit: i guess this one is more preferable
Set the timeout duration and call logout funtion
Timer(Duration(seconds: 5), () => logOut());
