我遇到以下问题，希望有人可以帮助我。我尝试使用以下代码将相机包含在我的 flutter 应用程序中：

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:camera/camera.dart';


class Route02 extends StatefulWidget {
  @override
  CameraState createState() => CameraState();
}

class CameraState extends State<Route02> {
  late List<CameraDescription> cameras;
  late CameraController _controller;
  bool isReady = false;

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

  Future<void> setupCameras() async {
    try {
      cameras = await availableCameras();
      _controller = new CameraController(cameras[0], ResolutionPreset.ultraHigh);
      await _controller.initialize();
    } on CameraException catch () {
      setState(() {
        isReady = false;
      });
    }
    setState(() {
      isReady = true;
    });
  }
