禁止使用 firebase_messaging >=7.0.3 <8.0.0-dev.7。扑动

Question

我想将firebase_messaging包添加到我的flutter应用程序中，但当我安装它时，出现了一个错误，它是：

Because firebase_messaging >=7.0.3 <8.0.0-dev.7 depends on firebase_core ^0.5.0+1 and elderly_app depends on firebase_core ^0.7.0, firebase_messaging >=7.0.3 <8.0.0-dev.7 is forbidden.
So, because elderly_app depends on firebase_messaging 7.0.3, version solving failed.
pub get failed (1; So, because elderly_app depends on firebase_messaging 7.0.3, version solving failed.)

我试着安装了两个版本的firebase_messaging，它们是：

firebase_messaging: ^9.0.0和firebase_messaging: 7.0.3并且也出现相同的错误。

这些是我在pubspec.yaml:中的dependencies

dependencies:

flutter:
sdk: flutter
flutter_localizations:
sdk: flutter
ff_navigation_bar: ^0.1.5
calendar_timeline: ^0.7.0

尝试删除版本号并像这样使用：

firebase_messaging:

Answer 2

您必须更新核心版本，同时保持所有firebase产品的最新版本，使用以下最新版本，否则您将面临很多问题：

firebase_messaging: ^9.0.0
firebase_core: ^1.0.1
firebase_auth: ^1.0.1
cloud_firestore: ^1.0.1

你可以通过运行"flutter pub过时"来了解你使用的每个软件包的更新
