Login on iOS (14.2) opens a web view dialog instead of the Facebook app #139

I'm not a regular iOS user, so I'm not sure if this is a bug or if this is the way it's supposed to work on iOS.

I'm using version ^3.3.3-no-nullsafety of the plugin because I haven't migrated my project to null safety.

The login is working, but I always get the web view dialog on iOS (only tested with iOS 14.2). On Android, it opens the a "native" Facebook dialog and lets me login with a single click. On iOS I have to type my password in the web view even though I'm already logged into the Facebook app, which kind of defeats a big part of the UX-purpose of providing a social login.

After installing some "big name" apps, it seems that even they use the web view when logging in with Facebook, so maybe this is just how Apple wants it to work? Would be great if someone could clarify, as the LoginBehavior flags doesn't seem to do anything on iOS.

I am not sure but maybe you can use this version flutter_facebook_auth: ^3.5.0 in a no null safety project. let me know if the problem persists

I tried with iPhone 7. And yes, I will give it a try with newer iOS.

kevindaizj commented 2 years ago

@darwin-morocho I have tried with iOS 14.7.1 (newest iOS) , real device.
Nothing changed. The plugin still open a webview that redirects to facebook.com instead of launching Facebook App.

Sorry but i could not reproduce it. it seems a bug of the Facebook sdk on iOS please go to the oficial Facebook sdk repository on iOS and open an issue there
