   I suspect the issue might have something to do with async initialization and update
   I cannot test it myself, but maybe you can try with the code sample below?

   code sample

   import 'package:camera/camera.dart';
   import 'package:flutter/material.dart';
   import 'package:flutter/services.dart';
   
   void main() async {
     WidgetsFlutterBinding.ensureInitialized();
     await SystemChrome.setPreferredOrientations(
       [DeviceOrientation.portraitUp],
     );
   
     runApp(
       const AppLifecycleWidget(child: Mypp()),
     );
   }
   
   class Mypp extends StatelessWidget {
     const Mypp({super.key});
   
     @override
     Widget build(context) => MaterialApp(
           title: 'Stream Test',
           theme: ThemeData(
             primarySwatch: Colors.blue,
             visualDensity: VisualDensity.adaptivePlatformDensity,

   }

     const MyHomePage({super.key});

   It seems like your code sample doesn't image stream at all. I am facing an issue with the image streaming. When I comment out startImageStream, I don't have any errors.

   Hi @RishabhK12
   I have waited 5 minutes but didn't see the exception as yours. I see this code on your sample code, is there any action on the device to fall into one of these cases?

   @override
   void didChangeAppLifecycleState(AppLifecycleState state) async {
     switch (state) {
       case AppLifecycleState.inactive:
         _cameraController?.stopImageStream();
         break;
       case AppLifecycleState.resumed:
         _initStateAsync();
         break;
       default:
     }
   }

   It would be better if you could provide clearer and concrete steps to reproduce this. Thanks!

   @huycozy

   I can reproduce the issue exactly as @RishabhK12 described,
   (just start remember to "move the phone around" to make the camera do some work)

   please find below a very minimal code sample below (reproduces with the code above as well)

   you can find the device details in the doctor

   minimal code sample

   import 'package:camera/camera.dart';
   import 'package:flutter/material.dart';
   import 'package:flutter/services.dart';
   
   void main() async {
     WidgetsFlutterBinding.ensureInitialized();
     await SystemChrome.setPreferredOrientations(
       [DeviceOrientation.portraitUp],
     );
     final cameras = await availableCameras();
     final controller = CameraController(
       cameras[0],
       enableAudio: true,
       ResolutionPreset.high,
     );
     int? hash;
     await controller.initialize();
     await controller.startImageStream((_) {
       if (hash == null) {
         print('''
       ################
       
       
       ${controller.hashCode}
       
   
       ################
       ''');
         hash = controller.hashCode;
       }
     });
     runApp(
       MaterialApp(
         home: Scaffold(
           body: Center(
             child: CameraPreview(controller),
           ),
         ),
       ),
     );
   }

   (just start remember to "move the phone around" to make the camera do some work)

   I did but still couldn't reproduce this on my device Pixel 7, Android 14 using the latest packages:

   camera:

     version: "0.6.7+2"

   Can you both share the fetched camera_android_camerax version from pubspec.lock file?

   AndroidCameraCameraX._configureImageAnalysis.analyze (package:camera_android_camerax/src/android_camera_camerax.dart:1236:7)

   Checking the error trace, it seems to fall analyze method here but doesn't match the line of code. So it's worth checking on the latest version of package.

    Thank you. I can see the same camera_android_camerax version as mine (0.6.7+2) on @iapicca comment. I still can't reproduce this issue but will label this for further input from others.

    @andynewman10 My work on this is still in progress. The draft of the changes is here: flutter/packages#8618. The new implementation compiles, but I'm still in the process to updating the tests.

    Update: flutter/packages#8618 has landed. I wasn't able to reproduce the NullPointerException exception before or after this PR with an old Moto G7 though.

    Please see if it you still get the NullPointerException after upgrading camera_android_camerax to ^0.6.15+2. And if so, please also provide the new error logs.

    @bparrishMines I have tried version 0.6.15 a few times about 8 days ago, and I repeatedly did not observe the issue, even when running the camera for a long time.

    I use camera: ^0.11.1, how do I update it?
