🐛 [firebase_dynamic_links: 4.1.0] No link is retrived both on initial & listen methods

[irajeshh]

Bug report

Describe the bug
firebase_dynamic_links version 4.0.7 was working properly, but it was updated to 4.1.0.
So the firebase_dynamic_links_platform_interface also updated from 0.2.1 to '0.2.2'.

Whenever a dynamic link is retrived, Unhandled Exception: type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, String>' exception was thrown in debug mode.

I came to find it was caused by the new object utmParameters in PendingDynamicLinkData.dart file.

Steps to reproduce

Steps to reproduce the behavior:

1. firebase_dynamic_links: 4.1.0
2. create a short dynamic link only with the following

DynamicLinkParameters parameters = DynamicLinkParameters(
      uriPrefix: uriPrefix,
      link: link,
      androidParameters: _androidParameters(),
      socialMetaTagParameters: socialMetaTagParameters,
    );

3. retrive the created url witht the following code

  final PendingDynamicLinkData? data = await dynamicLinks.getDynamicLink(Uri.parse(Link));
  final Uri? deepLink = data?.link;
  print(deepLink);

Expected behavior

Sample project

ElevatedButton(
            child: const Text('getDynamicLink'),
            onPressed: () async {
              FirebaseDynamicLinks dynamicLinks = FirebaseDynamicLinks.instance;
              
              String firstlink = "https://created.dynamic.link/abc";
              print("firstlink:$firstlink");
              Uri uri = Uri.parse(firstlink);
              final PendingDynamicLinkData? data =  await dynamicLinks.getDynamicLink(uri);
              final Uri? deepLink = data?.link;
              print(deepLink);
            },
          ),

After clean build,
Forcefully using the below versions solved the issue.
firebase_dynamic_links: 4.0.7 [in your pubsec.yaml[
firebase_dynamic_links_platform_interface: 0.2.1 [in the firebase_dynamic_links: 4.0.7 folder's pubspec.yaml file]

[Peeyush14198]

Facing a similar issue the app gets opened but every time the data is null by both methods getInitailLink and onLInk stream

[alarmatwork]

Can confirm.. link data is NULL.. it would be great help to write test around main functionality

You have to lock also version: firebase_dynamic_links_platform_interface: 0.2.1

[pedrohsampaioo]

got it! it's working now!!! Thanks @alarmatwork @irajeshh

[darshankawar]

I believe the said error:

Unhandled Exception: type '_InternalLinkedHashMap<Object?, Object?>' is not a subtype of type 'Map<String, String>' is causing due to the fix made to the latest plugin version : 32d06e7

And this issue comment mentions same error: 32d06e7#commitcomment-68482461

This PR fixes the type cast issue: #8263 that you can subscribe to.

Also, there's a similar open issue describing the same case in which you can follow-up for further updates: #8261
Closing this as a duplicate.
