Flutter 应用程序未使用 cloud_firestore 插件编译

Question

我已经在android/app 下添加了google-service.json。但是当我尝试构建应用程序时收到错误消息。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':cloud_firestore:processDebugGoogleServices'.
   > Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.4.2.

我试过flutter clean -> flutter packages get 但它不能解决我的问题。

pubspec.yaml

version: 1.0.0+1

environment:
    sdk: ">=2.0.0-dev.68.0 <3.0.0"

dependencies:
    flutter:
        sdk: flutter

    cupertino_icons: ^0.1.2
    http: ^0.11.3+17
    json_annotation: ^0.2.3
    cloud_firestore: ^0.8.0

app/build.gradle

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:multidex:1.0.3'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

apply plugin: 'com.google.gms.google-services'

我没有添加implementation 'com.google.firebase:firebase-core:16.0.3' 和implementation 'com.google.firebase:firebase-database:16.0.2'，因为我遵循codelab 指南。(https://codelabs.developers.google.com/codelabs/flutter-firebase/#5)

此行指定插件的版本 3.2.1（此时不要使用版本 3.3.0 或 3.3.1）。 有关详细信息，请参阅将 Firebase 添加到您的 Android 项目文档中的添加 SDK 部分（但不要遵循这些说明，因为它们与 Flutter 说明不同）。

build.gradle（项目）

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:3.2.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

更新

我还尝试将 gradle 版本更新到 4.6。 文件 -> 项目结构 -> 项目

dependencies {
  classpath 'com.android.tools.build:gradle:3.2.0'
  classpath 'com.google.gms:google-services:4.1.0'
}

但仍然出现错误。

如果我尝试了 gradle 同步，

Unable to resolve dependency for ':app@dynamicProfile/compileClasspath': Could not resolve project :cloud_firestore.

Unable to resolve dependency for ':app@dynamicProfile/compileClasspath': Could not resolve project :firebase_core.

并尝试构建颤振二进制文件，

自行解决

对于cloud_firestore，使用0.7.4 版本而不是0.8.0。

更改 gradle 依赖项

dependencies {
  classpath 'com.android.tools.build:gradle:3.1.2'
  ...
}

使用multiDex

这对我有用。

Flutterfire 最近推出了仅限 Dart 的初始化，这应该有助于防止发生类似的设置问题。按照他们文档中列出的guide 从手动平台特定设置迁移到仅 Dart 初始化。
