IOS does not report firebase_previous_screen with firebase analytics #7160

Discussed in https://github.com/FirebaseExtended/flutterfire/discussions/7155

Originally posted by **dennisvanmaren** October 7, 2021 Hi With firebase analytics on Android we receive the firebase_previous_screen parameters but with IOS this field is empty. Anyone have any idea how to get the firebase_previous_screen values? We use FirebaseAnalytics().setCurrentScreen to set the current screenname when a screen transition occurs. ![image](https://user-images.githubusercontent.com/58005483/136331994-d8e1e6f3-1238-4c5f-80e9-5907969fe904.png) Thanks Dennis

@dennisvanmaren Can you provide flutter doctor -v and a self-contained minimal reproducible code sample that we can use to verify this ? Thanks.

Hi darshankawar,

Thanks for helping, below the flutter doctor -v from codemagic which we are using for our IOS builds.

Accidently pressed the close button :-(

@dennisvanmaren Is it occuring in CI/CD ? or locally ? Are you able to replicate this behavior locally ? Can you try the official plugin example and see if you get same issue or not ? Thanks.

dennisvanmaren commented 3 years ago

Hi darshankawar,

Thanks to the example app we found the issue, the firebase_previous_screen was filled with IOS but the engagement_time_msec isn't available in IOS. Our SQL query filtered all events with no engagement time so it looks like we didn't receive any event with firebase_previous_screen.

We also found the following information regarding IOS and engagement_time_msec link

It is also discussed here Link

Will send a message to firebase support to see if they will include the engagement_time_msec in the screen_view events.

Thanks for your help

Dennis

Thanks for identifying the root cause and providing updates here. I am going ahead and closing this as non-issue.
