I checked this on my Pixel 7 Android 14 and saw the same output result as 0 on the sample app. To reproduce this, I add a new file to the package example project at lib folder:

Complete sample code

import 'package:flutter/material.dart';

import 'camera_controller.dart';
import 'camera_image.dart';
import 'camera_preview.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  CameraController? _controller;

  int _counter = 0;

  @override
  void initState() {
    super.initState();
    _initializeCamera();
  }

  Future<void> _initializeCamera() async {
    final cameras = await availableCameras();
    final firstCamera = cameras.first;
    _controller = CameraController(firstCamera);
    await _controller!.initialize();
    if (mounted) {
      setState(() {});
    }

    _controller!.startVideoRecording(onAvailable: _onImage);
  }

  void _onImage(CameraImage image) {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Stack(
        children: [
          Padding(
            padding: const EdgeInsets.all(32.0),
            child: Center(
              child: _controller != null
                  ? CameraPreview(_controller!)
                  : const CircularProgressIndicator(),
            ),
          ),
          Positioned(
            bottom: 16,
            right: 16,
            child: Text('images received: $_counter'),
          ),
        ],
      ),
    );
  }
}

flutter doctor -v
