I'm using Flutter and recently released my app to the public. It's working well for most people, but some users have reported it crashing when reaching the home page after signing up. I checked their data in Firebase and it's clean. They have tried reinstalling and going through the initial process again, entering data that works for everyone else and it still crashes. I got the device type of two of those users and they both have the same.
How can I find out what's causing the crash for these users, without having their specific device?
