🐛 [firebase_dynamic_links] iOS app not receiving link

[yarn-rp]

Bug report

Describe the bug
When user taps on dynamic link previously generated in iOS, app is opened but without any link. Android works as expected, opening the app and receiving the link properly. This behavior happens in both background/foreground and killed app status.
I'm using as dependencies :
firebase_dynamic_links: 4.0.7
firebase_dynamic_links_platform_interface: 0.2.1

Steps to reproduce

User taps on firebase dynamic link

Expected behavior

Firebase opens app with dynamic link and getInitialLink or FirebaseDynamicLinks.instance.onLink functions return something

Sample project

Here is my receiving links implementation:

import 'dart:async';

import 'package:firebase_dynamic_links/firebase_dynamic_links.dart';
import 'package:recarguita/core/referrals/dynamic_links_service/dynamic_links_service.dart';

class DynamicLinksService implements IDynamicLinksService {
  DynamicLinksService() {
    _initSubscription();
  }
  final StreamController<Uri> _linksController =
      StreamController<Uri>.broadcast();

  @override
  Stream<Uri> get linksStream => _linksController.stream;

  /// Subscribes to [FirebaseDynamicLinks] and sinks parsed
  /// [Uri] links to [_linksController]
  FutureOr<void> _initSubscription() async {
    // hot fix to wait til app is actually available
    await Future.delayed(const Duration(seconds: 2));
    // Get any messages which caused the application to open from
    // a terminated state.
    // Get any initial links
    final pendingDynamicLinkData =
        await FirebaseDynamicLinks.instance.getInitialLink();

    if (pendingDynamicLinkData != null) {
      _onReceivedKilledAppNotification(pendingDynamicLinkData);
    }

    FirebaseDynamicLinks.instance.onLink
        .listen(_onReceivedForegroundOrBackgroundDynamicLink);
  }

  void _onReceivedKilledAppNotification(PendingDynamicLinkData message) =>
      _linksController.sink.add(message.link);

  void _onReceivedForegroundOrBackgroundDynamicLink(
          PendingDynamicLinkData message) async =>
      _linksController.sink.add(message.link);
}

Additional context

I can't see any exception on the terminal when user taps the link, it's like nothing happened. With that said, i get some weird error logs when app launches in debug mode:

[Client] Updating selectors after delegate addition failed with: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service with pid 90 named com.apple.commcenter.coretelephony.xpc was invalidated from this process." UserInfo={NSDebugDescription=The connection to service with pid 90 named com.apple.commcenter.coretelephony.xpc was invalidated from this process.}

I tried to google it, but I haven't found anything really useful. I'm using XCode 13.3

Background issues
Also, when user leaves app in background, this log shows up multiple times:

As we can see in here, this seems to be an apple issue related with Firebase, I don't know if this might be the cause. If i remove dynamic links dependency from project, this still happens, and other firebase dependencies doesn't seems to be affected for this issue.

I am facing a similar issue in iPhone 11 , iOS 15.3.1 .

[anilthapa1939]

I am also facing a similar issue on iOS 12.5.1
No any error or exception on console either

I have a temporary solution using app_links. It's probably not the best solution, mainly because it removes some important firebase functionalities from the equation, but can get the job done for my specific usecase.

Generator functionality almost remains the same. The differences are in the type of link. Previously, I was making use of shortLinks, which are more "user friendly". With this approach, we can't make use of short links, because we can't parse the data from the link, since communication with firebase is not working properly. So, we generate a regular link with code below

import 'dart:async';
import 'dart:developer';

import 'package:firebase_dynamic_links/firebase_dynamic_links.dart';
import 'package:flutter_libphonenumber/flutter_libphonenumber.dart';
import 'package:fpdart/fpdart.dart';
import 'package:package_info_plus/package_info_plus.dart';
import 'package:recarguita/core/constants/constants.dart';
import 'package:recarguita/core/referrals/constants/constants.dart';
import 'package:recarguita/src/my_profile/model/my_profile_model.dart';

abstract class ReferralCodeGenerator {
  static Future<Option<Uri>> generateReferralCode(
      MyProfileModel myProfile) async {
    final _refferalCode = ((await FlutterLibphonenumber()
            .parse(myProfile.phone))['international'] as String)
        .replaceAll(RegExp('\\D+'), '');
    PackageInfo _packageInfo = await PackageInfo.fromPlatform();

    final parameters = DynamicLinkParameters(
      // The Dynamic Link URI domain. You can view created URIs on your Firebase console
      uriPrefix: kFirebaseUriPrefix,

      // The deep Link passed to your application which you can use to affect change
      link: Uri.parse('https://$kBaseUrl/referrals?code=$_refferalCode'),

      // Android application details needed for opening correct app on device/Play Store
      androidParameters: AndroidParameters(
        packageName: _packageInfo.packageName,
      ),

      // iOS application details needed for opening correct app on device/App Store
      iosParameters: IOSParameters(
        bundleId: _packageInfo.packageName,
      ),
    );
    try {
      final dynamicLink =
          await FirebaseDynamicLinks.instance.buildLink(parameters);
      return some(dynamicLink);
    } catch (e) {
      log('Error generating firebase dynamic link');
      return none();
    }
  }
}

Out of the app, firebase works as expected, taking user to the app store in case user doesn't have app installed and launching the app in case user has it installed.

Receiving the link, it's what changes more with this workaround. Firstly, since we can't establish properly communication with firebase in iOS, we have no Analytics, which is very important for the product. On the other hand, I'm actually depending on Firebase current type of link, but it can change tomorrow, letting my app useless. I'm hoping that there is a query parameter in url called link, which is very risky because its name can be easily changed. Code be like

import 'dart:async';
import 'dart:developer';
import 'dart:io';

import 'package:app_links/app_links.dart';
import 'package:firebase_dynamic_links/firebase_dynamic_links.dart';
import 'package:recarguita/core/referrals/dynamic_links_service/dynamic_links_service.dart';

class DynamicLinksService implements IDynamicLinksService {
  DynamicLinksService() {
    if (Platform.isIOS) {
      _initSubscriptionWithApplinks();
    } else {
      _initSubscriptionWithFirebase();
    }
  }

  final StreamController<Uri> _linksController =
      StreamController<Uri>.broadcast();

  @override
  Stream<Uri> get linksStream => _linksController.stream;

  FutureOr<void> _initSubscriptionWithApplinks() =>
      AppLinks().uriLinkStream.listen(_onAppLinkReceived);

  void _onAppLinkReceived(Uri uri) {
    try {
      final _link = uri.queryParameters['link'] as String;
      final _uriLink = Uri.parse(_link);
      _onReceivedLink(_uriLink);
    } catch (e) {
      log('Link was not a firebase dynamic link');
    }
  }

  /// Subscribes to [FirebaseDynamicLinks] and sinks parsed
  /// [Uri] links to [_linksController]
  FutureOr<void> _initSubscriptionWithFirebase() async {
    // hot fix to wait til app is actually available
    await Future.delayed(const Duration(seconds: 2));
    // Get any messages which caused the application to open from
    // a terminated state.
    // Get any initial links
    final pendingDynamicLinkData =
        await FirebaseDynamicLinks.instance.getInitialLink();

    if (pendingDynamicLinkData != null) {
      _onDynamicLinkReceived(pendingDynamicLinkData);
    }

    FirebaseDynamicLinks.instance.onLink.listen(
      _onDynamicLinkReceived,
      cancelOnError: false,
      onDone: () => log('done'),
      onError: (error, stacktrace) =>
          log('error $error with stacktrace: $stacktrace'),
    );
  }

  void _onDynamicLinkReceived(PendingDynamicLinkData message) =>
      _onReceivedLink(message.link);

  void _onReceivedLink(Uri link) => _linksController.sink.add(link);
}

As you can see, I'm missing a lot with this approach, but it works (for now).
