Flutter构建APK时遇Firebase.app及compileFlutterBuildDebug错误求助

问题现象 #

原本可正常从Firebase获取经纬度数据，尝试构建APK后出现错误，当前模拟器无法运行应用，核心错误：

• 在FirebaseFirestorePlatform.instanceFor(app: Firebase.app(appName))处提示找不到名为'Firebase'的getter
• 最终触发构建失败：Execution failed for task ':app:compileFlutterBuildDebug'
  移除所有Firebase代码后应用恢复正常，重新添加则重复触发错误。

问题根源与修复方案 #

1. 修复导入语句错误 #

main.dart中firebase_core的导入存在多余空格，导致编译器无法正确识别Firebase类：
原错误导入：

import 'package:firebase_core/firebase_core.dart  ';

修正后：

import 'package:firebase_core/firebase_core.dart';

2. 统一Firebase依赖版本 #

pubspec.yaml中部分Firebase依赖版本存在兼容性冲突，调整为相互兼容的版本：
修正后的pubspec.yaml依赖片段：

dependencies:
  flutter:
    sdk: flutter

  dio: ^4.0.0
  flutter_polyline_points: ^1.0.0
  google_maps_flutter: ^2.0.2
  cupertino_icons: ^1.0.2
  geolocator: ^9.0.2
  geocoding: ^2.0.4
  http:
  uuid: ^3.0.5
  google_place: ^0.4.7
  flutter_spinkit: ^5.1.0
  flutter_launcher_icons: ^0.11.0
  cloud_firestore: ^4.8.2
  firebase_database: ^10.2.8
  firebase_core: ^2.15.0
  firebase_auth: ^4.6.2

3. 清理缓存并重新构建 #

执行以下命令清理项目缓存，确保依赖正确加载：

flutter clean
flutter pub get

4. 确认Firebase初始化逻辑 #

main.dart中的初始化流程需保持正确顺序，确保在runApp前完成Firebase初始化：

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

修正后的完整代码示例 #

main.dart #

import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'MapScreen2.dart';
import 'SearchScreen.dart';

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Google Map',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MainScreen(),
    );
  }
}

class MainScreen extends StatefulWidget {
  const MainScreen({super.key});

  @override
  State<MainScreen> createState() => _MainScreenState();
}

class _MainScreenState extends State<MainScreen> {

  @override
  Widget build(BuildContext context) {
