Description

Hi

I'm using a library to monitor GPS locations called transistor. This library has a native implementation on Android and iOS from which does HTTP requests on the native side every x time.

I'm reporting this because the transistor SDK requests are not been caught by Firebase performance:

• I spoke with the library owner, and he says he is using Ok HTTP: https://github.com/transistorsoft/flutter_background_geolocation/issues/1243
• The network debugger on android studio does see the requests. I can see they are being done on the native side of android.

The only way I found is listening to the HTTP request events done by the transistor SDK, but| I lose the request time and payload size with that.

I already spoke with Firebase Support with someone named Amuel, and told me that its better to open an issue so that this issue is been taken this way and not via support, not sure why

Expected

I want to track this requests with Firebase performance because GPS tracking is a central feature of my app, and I am not able to do it.

I don't understand what is happening since the Firebase performance is already listening to other requests I do on the flutter side but not those done by the transistor SDK.

Reproducing the issue

Take a look at this project: https://github.com/danielgomezrico/transistor-sdk-and-firebase-performance-error-example

It uses:

• transistor SDK
• firebase performance monitoring
  • It is able to track the requests been done in the native android side, I wrote an activity that does requests, but the ones done by the transistor SDK are not.

Additional context and comments

I hope you could help me with this, It's pretty frustrating to have a core part of your app without a proper monitoring tool checking it.
