方法“收集”为Firebasestorage类型定义的IS不定义

Question

试图将数据存储在Firestore中，我会遇到错误。另一个问题是在Android Studio（Pixel 5）中使用我的仿真器，甚至使用我的所有4个连接设备。我可以跑步，但他们什么都没有表现出来。 Flutter医生发现没有问题。请帮助我tryna做一个我看不到的应用程序，而是利用我对它的外观的想象，这不是正确的方法。

import 'package:firebase_storage/firebase_storage.dart';
import 'package:get/get.dart';
import 'package:image_picker/image_picker.dart';
import 'dart:io';
import 'package:swift_mobile/constants.dart';
import 'user_model.dart' as model;

class AuthController extends GetxController{

  static AuthController instance = Get.find();

  late Rx<File?> _pickedImage;

  File? get profilePicture => _pickedImage.value;

  void pickAnImage() async {
  final pickedImage = await ImagePicker().pickImage(source: ImageSource.gallery);
  if(pickedImage!=null) {
    Get.snackbar('Profile Picture', 'You\'re good to go!');
   }
   _pickedImage = Rx<File?>(File(pickedImage!.path));
  }

  Future<String> _uploadToStorage(File image) async {
    Reference ref = firebaseStorage
        .ref().child('profilePictures')
        .child(firebaseAuth
        .currentUser!.uid
    );
    UploadTask uploadTusk = ref.putFile(image);
    TaskSnapshot snap = await uploadTusk;
    String downloadUrl = await snap.ref.getDownloadURL();
    return downloadUrl;
  }

  void registerUser(String username, String email, String password, File? image) async {
    try{
      if(username.isNotEmpty &&
          email.isNotEmpty &&
          password.isNotEmpty &&
          image!=null) {
       UserCredential cred =  await firebaseAuth.createUserWithEmailAndPassword(
           email: email, password: password);
        String downloadUrl = await _uploadToStorage(image);
        model.User user = model.User(name: username, email: email, uid: cred.user!.uid, profilePic: downloadUrl);

        await firestore.collection('user').doc(cred.user!.uid).set(user.toJson());
      } else {
        Get.snackbar(
            'Error creating account',
            'Please enter all fields',
        );
      }
    } catch(e) {
      Get.snackbar(
          'Error creating account',
          e.toString());
    }
  }
} ```

firebase.Collection用：

FirebaseFirestore.instance.collection

进口firestore。这与存储是不同的。
