越来越cloud_firestore：0.9.0依赖关系打破了扑扑的应用程序

标签： android firebase dart flutter package

我已将cloud_firestore: ^0.9.0软件包添加到新的flutter项目中，因此我创建了一个新的flutter项目，仅用于测试Firebase软件包。

在“打包获取”之后，并启动项目后出现此错误。

重新创建步骤：

  1. 复制pubspec.yaml cloud_firestore的Firebase软件包版本：^ 0.9.0并将其添加到pubspect.yamel文件中。并获得包裹。
  2. 在firebase网站上创建帐户后，下载了google-services.json。

  3. FLUTTERAPP / android / buld.grundle ive添加了这一行代码

    classpath'com.google.gms：google-services：4.2.0'

  4. FLUTTERAPP / android / app / build.grundle最后我添加了这样的代码

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

启动了应用程序。

我在Windows 10上将Android Studio与Android模拟器配合使用

    }
}

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

MY_APP / android / app / build.grundle 

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

问题[RE：Flutter如何解决。.dex文件中方法引用的数量不能超过64K。]可以通过将app / build.gradle minSdkVersion值从16更改为21来解决。与我以前遇到的问题相同（或相关），但有不同的错误消息。

您还应该添加要使用的Firebase SDK的依赖项。

添加implementation 'com.google.firebase:firebase-core:16.0.1'  到您的MY_APP / android / app / build.grandle文件中的依存关系部分，如下所示。

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    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'
    implementation 'com.google.firebase:firebase-core:16.0.1'
}

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