iOS app crashes when camera is streaming images #44436
Description
iOS app is being terminated when camera streams images after a few seconds. I'm using the camera plugin, up to date.
This problem occurred after I cherry-picked 9769754 to fix a severe black screen bug. I also tried to use the current beta, and the problem also occurs.
Stable channel is fine, no crashes.
Steps to Reproduce
- Download the example app from the camera plugin.
- Create the following function in main.dart:
void _startStreamingImages() {
controller.startImageStream((CameraImage image) {
print('Got image... It will crash in a few seconds.');
});
}
- Call the function above after initializing the controller (line 205):
try {
await controller.initialize();
_startStreamingImages();
} on CameraException catch (e) {
_showCameraException(e);
}
- Run the app and tap on the camera icon on the bottom left to start the camera.
Target Platform: iOS
Android seems to not crash.
Logs
When run in VS Code, the app just crashes without an explanation, but when run in Xcode we get an error message "Terminated due to memory issue".
