Event is fired several times #161

With the latest (maybe also with older versions) the event is fired several times (usually twice instead of once). This behavior no longer occurs with version 6.1.3.

Occurs with Android and Iphone

Disable default Flutter deep linking? https://github.com/llfbandit/app_links/blob/master/doc/README_ios.md#ios

I'm currently observing similar behavior on Flutter 3.22 when listening on the AppLinks().uriLinkStream. If I understood correctly, Flutter 3.22 shouldn't need explicit configuration / disablement as shown in the README you @llfbandit linked?

A simple debounce on the stream fixes my issue, but this isn't an ideal fix.

After conducting further investigation, I have determined that the issue is with our App. We are using a plugin called FlutterDownloader, which requires the use of setPluginRegistrantCallback in didFinishLaunchingWithOptions. When the callback is executed and it is not in the registry, it needs to register itself again.

When registering, we mistakenly called GeneratedPluginRegistrant.register(with: flutterPluginRegistry), which is incorrect. According to the plugins documentation, we should have called FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin")!).

Our mistake caused the SwiftAppLinksPlugin to call the addApplicationDelegate twice, resulting in the deeplink being sent to our App twice.

I apologize for the confusion, and I hope that my message can be useful to others in the future.
