Issue Description and Steps

How do i stop this error from being presented. This comes up in case of no internet or 404. I have already tried adding error handling to the code where i call api.

Hey send flutter doc report. This can be easily resolved

[adilwahla]

you need to check Internet Connection before going to Proceeds into the main screen. If the Internet connection is not available we can notify the user to Turn On the internet connection

please follow this and you will get out of this error [https://www.geeksforgeeks.org/how-to-check-internet-connection-in-flutter/]

@adilwahla , checking internet connection before proceeding is valid but no internet case is just one case where this is presented. It also comes when i get 404
