Question

我想在Flutter应用中使用Firebase，并且正在按照说明进行操作使用Firebase并得到该错误。

Launching lib\main.dart on Google Nexus 5X, 8 0, API 26, 1080x1920 in debug mode...
Initializing gradle...

Running Gradle task 'assembleDebug'...

ERROR: [TAG] Failed to resolve variable '${junit.version}'
ERROR: [TAG] Failed to resolve variable '${animal.sniffer.version}'

失败：构建失败，并出现异常。

出了什么问题：任务'：app：processDebugGoogleServices'的执行失败。

没有找到与包名'com.technoscans.neolearn'相匹配的客户端
尝试：

使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。与--scan一起运行以获得完整的见解。

这是build.gradle文件

buildscript {
    ext.kotlin_version = '1.2.71'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }
}

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

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

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

这是app / build.gradle文件

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'
}

            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'

尝试Flutter清洁，重新获得包装。并通过运行flutter run verbose发布更多信息。我对4.2版本一直很困难，所以使用 classpath'com.google.gms：google-services：3.2.0'

我在Flutter应用程式中使用Firebase，而这个错误向我显示
