Question

我有一个firebase flutter应用程序，一切正常，但是当我添加firebase_messaging：^ 5.1.4。该应用程序提供以下信息：

失败：构建失败，并出现异常。

* What went wrong:
Could not determine the dependencies of task ':app:preDebugBuild'.
> In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[18.0.
  0]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

  Dependency failing: com.google.firebase:firebase-messaging:18.0.0 -> com.google.firebase:firebase-iid@[18.0.0], but fire
  base-iid version was 19.0.0.

  The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
  ifact with the issue.
  -- Project 'app' depends on project 'firebase_messaging' which depends onto com.google.firebase:firebase-messaging@18.0.
  0
  -- Project 'app' depends onto com.google.firebase:firebase-core@17.0.0
  -- Project 'app' depends on project 'cloud_functions' which depends onto com.google.firebase:firebase-functions@17.0.0
  -- Project 'app' depends on project 'firebase_core' which depends onto com.google.firebase:firebase-core@16.0.9

  For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
  endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
  github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
  uild.gradle file.

这些是我的其他包裹

firebase_auth：^ 0.11.1 + 12 firebase_storage：^ 3.0.4 cloud_firestore：^ 0.12.7 + 1 cloud_functions：^ 0.4.1 + 1

（他们都工作）

我的构建包中有此文件：classpath'com.google.gms：google-services：4.2.0'

实现'com.google.firebase：firebase-core：17.0.0'

有没有办法解决这个问题？

非常感谢您！

Answer 1

我目前正在尝试：

在应用程序级别build.gradle中，我有这个：

应用插件：“ com.google.gms.google-services”

我要添加以下内容： com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

（在应用插件后：“ com.google.gms.google-services”）

Answer 2

在pub spec.yaml中包含Firebase Core依赖项，并且未指定firebase依赖项的版本可以解决大多数问题。

https://pub.dev/packages/firebase_core

Answer 3

运行这两行

rm Podfile.lock
pod install --repo-update

这些将完成工作。我花了两天时间来解决它
