我在更新 Firebase 软件包时遇到了同样的问题。
我创建了一个类来根据环境将FirebaseAnalytics 与模拟版本交换。然后将FirebaseAnalytics替换为包装类AnalyticsService。
这太老套了，我讨厌它。
如果有人有更好的方法，请分享。
import 'dart:io';
import 'package:firebase_analytics/firebase_analytics.dart';
import 'package:firebase_core/firebase_core.dart';
// The is class is needed because firebase is horrible and apparently hates developers
// - also calling `FirebaseAnalytics.instance` causes tests to fail
class AnalyticsService {
static get instance => Platform.environment.containsKey('FLUTTER_TEST') ? FakeFirebaseAnalytics() : FirebaseAnalytics.instance;
}

将此技巧应用于问题中的代码：
class FirebaseLogging {
static void log(String log) {
if (Platform.environment.containsKey('FLUTTER_TEST')) return;
FirebaseCrashlytics.instance.log(log);
}
}
