由于我在应用程序中添加了从firestore获取数据的功能，因此在运行flutter run时，我会收到以下错误：

字符串
下面是主要的.dart：

import 'package:flutter/material.dart';
import 'package:precio_luz/screens/main_screen.dart';

void main() {
  runApp(PrecioLuz());
}

class PrecioLuz extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'PrecioLuz',
      theme: ThemeData(
        primarySwatch: Colors.grey,
      ),
      home: MainScreen(),
    );
  }
}

型
还有我从firestore获取的文件：

int selectedDate =
      0; // 0 for 'Today', 1 for 'Tomorrow', 2 for 'Historical Day'
  String selectedHistoricalDate =
      '2023-4-17'; // Replace this with the selected date.

  Stream<DocumentSnapshot> getPricesStream() {
    FirebaseFirestore firestore = FirebaseFirestore.instance;

    switch (selectedDate) {
      case 0:
        return firestore
            .collection('electricityPrices')
            .doc('todayData')
            .snapshots();
      case 1:
        return firestore
            .collection('electricityPrices')
            .doc('tomorrowData')
            .snapshots();
      case 2:
        return firestore
            .collection('electricityPrices')
            .doc('historicalData')
            .collection('dates')
            .doc(selectedHistoricalDate)
            .snapshots();
      default:
        throw Exception('Invalid selectedDate: $selectedDate');
    }
  }
...

文件的其余部分无关紧要。这是什么问题，我该如何解决？
我已经尝试了清理和重建，升级Flutter，降级和升级包，以及更多的事情，但仍然没有解决这个问题。
