[deandreamatias-worldline]

Bug report

Describe the bug
After configure the debug mode for Firebase Analytics for iOS, on DebugView do not show the events.
Follow this official documentation and this StackOverflow answer
When launch app directly from XCode, works fine.

• [firebase_analytics] iOS Runtime Arguments Not Working #1586
• [firebase_analytics] iOS Arguments on Launch not working #844

Steps to reproduce

1. Integrate Firebase core + Firebase analytics, verify the app keys and configures
2. Enable debug mode. Open Xcode. SelctProduct->Scheme > Edit scheme. Select Run from the left menu. Select the Arguments tab. In the Arguments Passed On Launch section, add -FIRDebugEnabled or -FIRAnalyticsDebugEnabled (tested both).
3. Try to build project by VS Code (see launch configuration)
4. Check the Debug View and the no event emitted from the project built by VS Code.

Expected behavior

When enable debug mode, show the events on DebugView of Firebase.

Sample project

Use the example code of package and add a configuration to enable debug view

Thanks for the report @deandreamatias-worldline
As I understand, it occurs as expected if you run through XCode, but not when you try to run via VSCode. Is it a correct interpretation ?

Also, if you try to run directly via command line or terminal, can you check if it works or not ?

[deandreamatias-worldline]

Thats is correct @darshankawar.
What is the command that I can use to pass iOS arguments via Flutter CLI?

[darshankawar]

What is the command that I can use to pass iOS arguments via Flutter CLI?

I am not completely sure, but maybe using flavors could be one of the options.

Using example project, do you see the log entries such as [FirebaseAnalytics] ? If so, that might indicate the events maybe logging but may not be showing in analytics dashboard in firebase console ?

[deandreamatias-worldline]

I used flavors to build app, but this config need to update XCode config like this. So, do not have option to pass -FIRDebugEnabled directly by FlutterCLI

[darshankawar]

Thanks for the update. I don't use VSCode IDE so unable to verify it properly, but based on the report, keeping it open for team's attention / tracking.

[russellwheatley]

Hey @deandreamatias-worldline, there is no way to pass this argument -FIRDebugEnabled from the Flutter CLI. There was an issue on the Flutter repo which was closed and moved to this repo: flutter/flutter#17043

it is handled by the native Firebase SDK on launch, and AFAIK, cannot be changed retroactively via FlutterFire.

At the moment, you do have to run the app from Xcode unfortunately, there is no way around it.

[deandreamatias-worldline]

Ok. Thanks @russellwheatley for explanation

[TarekkMA]

@deandreamatias-worldline

Thank you for your report! This issue isn't on FlutterFire, but rather on Flutter itself. Please file an issue on Flutter to allow Xcode command line arguments. If you feel that this issue is still relevant after that, please feel free to open a new issue with updated context. We appreciate your understanding and support.

[TarekkMA]

And I see that the linked flutter issue has been closed
