handle http exceptions

[joukhar]

when user is not connected to internet, it return this error:
ClientException with SocketException: Failed host lookup: 'play.google.com' (OS Error: No address associated with hostname, errno = 7), uri=https://play.google.com/store/apps/details?id=<PACKAGE_ID>&hl=en_US

when app is not found it returns:
Unhandled Exception: Exception: Invalid response code: 404

My suggestions are:

1. when user is not connected to internet : mark canUpdate to false
2. when app is not found : add a parameter isAppExist and its value is false and mark canUpdate to false

and THANK YOU SO MUCH FOR UR WORK

Hello there, similar problem here.

In my case the app is not yet public, so there is an unhandled 404 error when trying to find the app on the Play Store:

E/flutter ( 4345): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Exception: Invalid response code: 404
E/flutter ( 4345): #0      NewVersionPlus._getAndroidStoreVersion (package:new_version_plus/new_version_plus.dart:191:7)
E/flutter ( 4345): <asynchronous suspension>
E/flutter ( 4345): #1      _ScreenState.checkUpdates (package:app/presentation/ui/screen/screen.dart:56:9)
E/flutter ( 4345): <asynchronous suspension>

@pewiher , is there any way to handle these errors?
