Flutter firebase版本冲突firebase消息传送

Question

我有一个firebase flutter应用程序，一切正常，但当我添加firebase_messaging时：^5.1.4。这个应用程序提供了以下功能：

失败:生成失败，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

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

(它们都有效)

我的构建gradle: 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!

Answer 1

我目前正在尝试这样做：

在应用程序级别的build.gradle中，我有以下内容：

应用插件：'com.google.gms.google-services‘

我添加了这个: com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

(应用插件后：'com.google.gms.google-services')

Answer 2

在pub spec.yaml中包含Firebase核心依赖项并不指定firebase依赖项的版本可以解决大多数问题。

https://pub.dev/packages/firebase_core

Answer 3

运行这两行代码

rm Podfile.lock
pod install --repo-update

这些将会完成这项工作。我花了两天时间才把它修好
