Flutter 错误：找不到符号导入 com.google.firebase.firestore.TransactionOptions

Question

Since the latest update to Cloud Firestore 3.4.3 I cannot build the Flutter app anymore.

    /Applications/flutter/.pub-cache/hosted/pub.dartlang.org/cloud_firestore-3.4.3/android/src/main/java/io/flutter/plugins/firebase/firestore/streamhandler/TransactionStreamHandler.java:13: error: cannot find symbol
import com.google.firebase.firestore.TransactionOptions;
                                    ^

            new TransactionOptions.Builder().setMaxAttempts(maxAttempts).build(),

I tried removing the folder /Applications/flutter/.pub-cache/hosted/pub.dartlang.org/cloud_firestore-3.4.3 and performing flutter clean. Moreover I downgraded cloud_firestore to 3.3.0, but the folder was reinstalled with the same 3.4.3 version.

Any suggestion?

Here's everything I did to get that error gone.

Per this link :

flutter upgrade --force --verbose&&flutter update-packages --force-upgrade&&flutter pub upgrade --major-versions

Add to my main.dart:

import 'package:firebase_auth_platform_interface/firebase_auth_platform_interface.dart' show FirebaseAuthPlatform;

Run flutter pub get -- notice no improvement.

So, additionally, I upgrade my pubspec.yaml manually:

firebase_core: ^1.21.0
cloud_firestore: ^3.3.0
firebase_auth: ^3.6.4
firebase_auth_platform_interface: ^6.5.4
cloud_firestore_odm: ^1.0.0-dev.27

Run flutter pub upgrade && fluter pub get

Now it works.
