[camera_android_camerax] Camera Image Stream is randomly stopping #152763
Description
What package does this bug report belong to?
camera
What target platforms are you seeing this bug on?
Android
Have you already upgraded your packages?
Yes
Steps to reproduce
- Execute
flutter runon the code below. This is using the latest version 0.11.0+1. - Wait and watch for the platform exception below to appear in the terminal. It usually happens after running it for a while. You may have to tap your phone every little bit to prevent it from falling asleep. Move the phone around a bit so the camera does some work.
Expected results
No exception is output and the image stream never stops.
Actual results
The image stream stops and the platform exception shown below in the log is output. This happens randomly, sometimes after running it for a few minutes, other times after running it for longer like 8ish minutes. This has been run on an s23 ultra. It happens quicker if I do something with the image that the stream is giving me. It doesn't happen if I comment out the startImageStream line.
