[firebase_dynamic_link] listener not being called on iOS

[quetool]

I have tried both on iOS 12 and 13 and FirebaseDynamicLinks.instance.onLink listener is not being called at all... App is opened just fine, but like I said, the listener is not being called...

[quetool]

I debugged my Dynamic Link and it looks fine...

[quetool]

So, finally I found the solution... In Dynamic Link firebase docs you will find this:

I must say this is not mentioned in the flutter plugin README doc
https://pub.dev/packages/firebase_dynamic_links#-readme-tab-

So adding that key I solved the issue...

Here it is the doc https://firebase.google.com/docs/dynamic-links/custom-domains?authuser=0

Hi @quetool,

Just wondering what you exactly managed to solve by adding the FirebaseDynamicLinksCustomDomains key. Did you manage to read the dynamic link, and its path, in flutter?

[quetool]

@HofmannZ yes, before I realize I needed to add that key on the info.plist dynamic links were not being readed at all, not from FirebaseDynamicLinks.instance.getInitialLink() nor even from FirebaseDynamicLinks.instance.onLink

[HofmannZ]

@quetool managed to get that working, though the onLink seems to subscribe multiple times and has no dispose method :s Did you get that to work?

[quetool]

@HofmannZ you need to add the onLink listener once in an initState() method or in a singleton class. I think you are instantiating the FirebaseDynamicLinks more than one time.

[HofmannZ]

@quetool Yeah came to that conclusion as well. The only problem I had was that I was calling onLink from inside each page, without the putting FirebaseDynamicLinks inside a singleton. Puting it inside a singleton should solve the issue.

Also using initState outside MaterialApp is not ideal because you don't have to context of the Navigator

[quetool]

I have a main container class (a stateful widget) that contains the entire app. On its initState method I instantiate the FirebaseDynamicLinks.instance with its onLink method. Then I use streams to communicate the link parsing result wherever I want to. But that's my approach.

[HofmannZ]

@quetool how did you solve getting the Navigator context? Using navigatorKey I'm guessing?

[quetool]

Maybe is better if you provide some code and an explanation on what you need to do... I do not have problem getting current context becauase like I said I manage everything inside a stateful widget... Anyway, this is just for issues, maybe you can open a question on SO

[HofmannZ]

PR #255 managed to fix my issue, thanks!

[quetool]

I do not have that sort of problems described on that PR but ok
