iOS Universal Links not working correctly with Flutter 3.24

[aem-mmandai]

Describe the bug

Once I upgraded my application to Flutter 3.24.2 my Universal Links on iOS stopped working. Or at least: they are not working as intended.

I am using app_links version 6.3.2.

Expected behaviour:
Click on universal link opens the app and the appropriate page.

Observed behaviour:
Click on Universal Links opens the app. Quickly after that the native browser is opened with the link as target. In my logs I see a warning "Failed to handle route information in Flutter.".

Downgrading to Flutter 3.22.3 resolved this issue for me.

Does it related to

[ ] App Links (Android)
[ ] Deep Links (Android)
[✓] Universal Links (iOS)
[ ] or Custom URL schemes? (iOS)

Does the example project work?

[ ] Yes
[✓] No
[ ] Irrelevant here

Did you fully read the instructions for the targeted platform before submitting this issue?

Uploaded your files to webserver, HTTPS, direct connection, scheme pattern setup, ...

[✓] Yes
[ ] No
[ ] Irrelevant here

Thanks for the report.

It looks like Flutter team has enabled their default deep linking feature by default...
flutter/engine#52350

So, you must refer to docs to disable it explicitly now for Android & iOS.

I also face this error and the solution for me was to add some code in the AppDelegate.swift file

  // ALREADY STARTED
  // This method called if the app is already running or running in the background and the user clicks on universal links.
  override func application(
    _ application: UIApplication,
    continue userActivity: NSUserActivity,
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
  ) -> Bool {
    // Checking if we received a universal link
    if let incomingUrl = userActivity.webpageURL {
      print("[AppDelegate] => App received universal link: \(incomingUrl)")
      AppLinks.shared.handleLink(url: incomingUrl)
      return true
    }
    
    return super.application(application, continue: userActivity, restorationHandler: restorationHandler)
  }

I need to ovveride application func when app already opened and i clickec on link
also need to add this piece of code to this function

override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) - called when app is staring

if let url = AppLinks.shared.getLink(launchOptions: launchOptions) {
      // We have a link, propagate it to your Flutter app
      print("[AppDelegate] => Received Url = \(url)")
      AppLinks.shared.handleLink(url: url)
      // Returning true will stop the propagation to other packages
      return true 
    }

Thanks for supporting!!

I solved this problem by adding the following settings to my project.

ios/Runner/Info.plist

<key>FlutterDeepLinkingEnabled</key>
<false/>
