flutter 错误 : cannot find symbol import com. google.firebase.firestore.TransactionOptions

Question

自从 Cloud Firestore 3.4.3 的最新更新后，我无法再构建 Flutter 应用。

    /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;
                                    ^
  symbol:   class TransactionOptions
  location: package com.google.firebase.firestore
/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:66: error: package TransactionOptions does not exist
            new TransactionOptions.Builder().setMaxAttempts(maxAttempts).build(),
                                  ^

我尝试删除文件夹 /Applications/flutter/.pub-cache/hosted/pub.dartlang.org/cloud_firestore-3.4.3 并执行 flutter clean。此外，我将 cloud_firestore 降级为 3.3.0，但该文件夹重新安装了相同的 3.4.3 版本。

有什么建议吗？

这是我为消除该错误所做的一切。

根据 this link :

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

添加到我的 main.dart 中:

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

运行 flutter pub get——注意没有改善。

因此，另外，我手动升级我的 pubspec.yaml:

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

运行 flutter pub upgrade && flutter pub get

现在可以了。
