GA4 Consent Mode & Firebase Analytics / setAnalyticsCollectionEnabled

[Eric Ho]

Hi,

Is there anyone have experienced setting up Consent Mode along side with Firebase Analytics (GA4) in an app project?

Base on this information from the following websites 

https://developers.google.com/tag-platform/devguides/app-consent?platform=ios

https://support.google.com/analytics/answer/99761https://firebase.google.com/docs/analytics/configure-data-collection?platform=ios01?hl=en

I can adapt consent mode by enable this with the following code and the analyticsSignal / adSignal are came from Consent Management Platform. 

Analytics.setConsent([.analyticsStorage: analyticsSignal ? .granted : .denied , .adStorage: adSignal ? .granted : .denied])

With the above setup, do I need to enable the analytics collection all the time (e.g by setting this isAnalyticsTrackingEnableFlag =  true)

e.g . Analytics.setAnalyticsCollectionEnabled(isAnalyticsTrackingEnableFlag)

or I can still need to enable the analytics collection based on some sort of consent flag? 

let isAnalyticsTrackingEnable:Bool = someConsentFlag 

Analytics.setAnalyticsCollectionEnabled(isAnalyticsTrackingEnable)

But what if the someConsentFlag is set to false and no analytics data will be fired based on the current implementation, will the Consent Mode setup have any effect (e.g. is the Google Analytics SDK for Firebase stills able to send out ping signal to GA4?)
