iOS app link handling issue while app is in running state (when app is launched with a link)

[arreshashikant]

Steps to reproduce:
singular_flutter_sdk: ^1.0.15

1. Launch iOS app from terminated state with a link (singularLinksHandler is invoked, No issues)
2. Now, click on the link from any other app (app is in running state). The callback singularLinksHandler is NOT invoked

This is because of the following code in iOS

if ([SingularAppDelegate shared].launchOptions != nil) {
        config.launchOptions = [SingularAppDelegate shared].launchOptions;
    } else if ([SingularAppDelegate shared].userActivity != nil) {
        config.userActivity = [SingularAppDelegate shared].userActivity;
    } else if ([SingularAppDelegate shared].openURL != nil) {
        config.openUrl = [SingularAppDelegate shared].openURL;
    } else {
        NSLog(@"everything is null");
    }

Quick fix I found:

    override func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
        
        if let singularAppDelegate = SingularAppDelegate.shared() {
            if let singularAppDelegate = SingularAppDelegate.shared() {
                singularAppDelegate.launchOptions = nil
            }
            singularAppDelegate.continueUserActivity(userActivity, restorationHandler:nil)
        }
        return super.application(application, continue: userActivity, restorationHandler: restorationHandler)
    }

I had the exact same issue. @arreshashikant solution fixed it though 😁
