This plugin only connect with the native Facebook sdk if you have a wrong configuration in your console I can't do any more. Also go to the oficial Facebook sdk repository and check if other users has the same problem.

I've tested on my real iPhone X with ios 14.5 without any problem. https://user-images.githubusercontent.com/15864336/127741435-6b476c64-d472-41ac-843b-f2b1442e4a8e.MP4

Maybe is a problem with the facebook sdk for ios the current version in this plugin is 11.0.0 so try to use flutter_facebook_auth:3.4.1 that version use the facebook sdk 9.1.0 first follow the migration guide to avoid problems https://facebook.meedu.app/#/migration-guide next install flutter_facebook_auth:3.4.1

it is because you may be adding key hashes with '0x' groups. try to convert you SHA1 key here http://tomeko.net/online_tools/hex_to_base64.php without checking ' remove "0x" groups from input' It worked in my case

May be iOS [AppDelegate application:openURL:options:] method blocked

My AppDelegate.m

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
    if ([Growing handleUrl:url]) 
        return YES;
    }
    return [super application:app openURL:url options:options];

I am not sure because I'm not an objective-c developer for that reason this plugin only works with swift but you can try adding

  [[FBSDKApplicationDelegate sharedInstance] application:application
                                                 openURL:url
                                                 options:options];

in your method

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
- 
  [[FBSDKApplicationDelegate sharedInstance] application:application
                                                 openURL:url
                                                 options:options];
    if ([Growing handleUrl:url]) 
        return YES;
    }
    return [super application:app openURL:url options:options];
}

for more info go to https://developers.facebook.com/docs/facebook-login/ios?locale=en_US

objective-c can also work normally, but it doesn’t work if I write it like this

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
    if ([Growing handleUrl:url]) 
        return YES;
    }
    return NO;
}

so if you use other SDKs, they must be compatible, don't return NO directly, but pass backwards

change to return [super application:app openURL:url options:options]; it works normally

of course, you can also add [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
