使用 flutter 处理 Appcheck 时出错

我想在 firebase 存储中上传文件，但经过多次研究后出现了 appcheck 错误，我发现我必须在 firebase 上激活 Appcheck，而且还要在我的应用程序上激活它

在 youtube 上的谷歌视频中，我看到我必须在构建我的应用程序时调用此函数：

初始化Firebase(){

FirebaseApp.initializeApp(/*context*/ this);
FirebaseAppCheck firebaseAppCheck = FirebaseAppCheck.getInstance();
firebaseAppCheck.installAppCheckProviderFactory(
SafetyNetAppCheckProviderFactory.getInstance());

}

但我有错误，未定义方法“initializeApp”；“getInstance”和“installAppCheckProviderFactory”，

Your MainActivity.kt应该看起来像这样：

package com.example.app //your package name

import androidx.annotation.NonNull
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import com.google.firebase.FirebaseApp
import com.google.firebase.appcheck.FirebaseAppCheck
import com.google.firebase.appcheck.debug.DebugAppCheckProviderFactory

class MainActivity: FlutterActivity() {
    private val CHANNEL = "samples.flutter.dev/battery"

    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler {
            call, result ->
            FirebaseApp.initializeApp(/*context=*/this)
            val firebaseAppCheck = FirebaseAppCheck.getInstance()
            firebaseAppCheck.installAppCheckProviderFactory(
                    DebugAppCheckProviderFactory.getInstance()
            )
        }
    }
}

和你的main.dart像这样：

import 'package:firebase_app_check/firebase_app_check.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  await FirebaseAppCheck.instance.activate();
}
