Flutter ios app devloper

I ned to get a developer who can check a camera pod module in an app why it is not working and receiving information from the camera.

What we know:
1. it has worked previously
2. the flutter can executethe camera since we are getting results from it in one parameter
3. we receive response from the camera in one parameter
4. according to the developer the other parameters are not being received
5. Another ios developer says the camera module works and it has not been changed for the past 3 motnhs and prior to that not for the past 6 months and no changes are in the api communication

I ned someone who is rock solid on using Flutter as the main app and using ios camerapod as the add in module that flutter is using.

I know this is a small job, but the current developer is not capable of resolving it.
