Analytics messages not listed in the Firebase analytics "DebugView" / How to debug firebase analytics code used in a flutter web site?

[Dietrich Bollmann]

Hi, 

  

I am developing a web site with Flutter web.  During the development I use the Flutter "chrome device" to preview and experiment with the code.  Currently I am trying to integrate firebase analytics...

In order to trace the messages arriving at Firebase / Google analytics I would like to use the "DebugView" in the Firebase / Google analytics online console.  As far as I understand messages are only shown in the DebugView when the "Google Analytics Debugger" extension has been installed and activated in the Chrome browser.

Unfortunately it seems to be impossible to install the plugin in the Chrome preview device used by Flutter.  I therefore installed the plugin in my "normal" Chrome browser.  Now I first use flutter to start the chrome device and then copy over the URL into my "normal" Chrome browser with the Google analytics debugger extension activated.

Unfortunately, using this setup, most of the sent analytics messages are not shown in the DebugView.  Only from time to time a message finds its way into the DebugView and I seem to be unable to see a pattern.  Most of the messages are shown in the console of my browser but seem to not reach the Firebase analytics console - or are at least not shown in the DebugView.

I don't know what I am doing wrong.  Maybe I have to use another setup to test Firebase / Google analytics?  I would be grateful for any help how to solve the problem or how to debug my Firebase analytics code.

Thanks for your help,
