Using Navigator without context
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a class that wraps http calls (get, post, delete).
What I need to achieve is a way to check every api response to be able to force a logout if, for example, a token is expired.
Let's say I'm logged in my app and my token expires; I then try to list my posts with a call like this:
var results = api.get('http://api.site.com/user/123/posts')
get(String endpoint) async {
return http.get(endpoint,
headers: headers(),
).then((response) {
var result = json.decode(response.body);
if (result['force_logout'] == true) {
UserServices.logout(); // delete secure storage data and other stuff
Navigator.of(context).pushNamedAndRemoveUntil('/login', (Route<dynamic> route) => false);
}
return result;
});
}
Inside my api get method I would like to be able to perform the user logout and navigate to the login screen, but how can I do it without having a context?

You can't do that. You need to bind yourapito the context somehow

Maybe passingcontextin every api method call?

Bad idea. A custom class would be better
