在flutter中有没有image_picker的替代品？因为我不能同时使用image_picker和barcode_scanner

import 'package:file_picker/file_picker.dart';

Future<void> _pickImage() async {
  try {
    FilePickerResult? result = await FilePicker.platform.pickFiles(type: FileType.image);

    if (result != null) {
      File file = File(result.files.single.path!);
      // 处理文件
    } else {
      // 用户取消了选择
    }
  } on PlatformException catch (e) {
    print("Error while picking the file: $e");
  }
}

import 'package:image_gallery_saver/image_gallery_saver.dart';

Future<void> _saveImage() async {
  try {
    final imageFile = await DefaultAssetBundle.of(context).load("assets/sample.jpg");
    final bytes = await imageFile.buffer.asUint8List();
    final result = await ImageGallerySaver.saveImage(bytes);
    print("Saved to gallery: $result");
  } catch (e) {
    print("Error saving image: $e");
  }
}

import 'package:camera/camera.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final cameras = await availableCameras();
  final firstCamera = cameras.first;

  runApp(MyApp(camera: firstCamera));
}

class MyApp extends StatelessWidget {
  final CameraDescription camera;

  MyApp({required this.camera});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: CameraPreview(camera),
      ),
    );
  }
}
