尝试将数据推送到 Firebase 时，Flutter 应用程序中断

Question

所以我正在使用 firebase 插件并按照谷歌所说的将其连接到 firebase 的所有操作，但如果我尝试添加（创建）某些东西，它会破坏应用程序。

这是我的 Firebase 设置：

我已经从 firebase 下载了 google-services.json 添加到 application/build.grandle：

dependencies {
    classpath 'com.google.gms:google-services:4.2.0'
    classpath 'com.android.tools.build:gradle:3.3.2'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

我的 grundle 文件到 application/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'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.comp.appname"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'com.google.firebase:firebase-core:16.0.8'
    implementation 'com.google.firebase:firebase-firestore:18.1.0'
    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'
}
apply plugin: 'com.google.gms.google-services'

这是有错误的构建

值得一提的是，我使用了代理，但它的配置正确，并且可以与其他应用一起使用

解决了，

我不得不像这样降级构建 gradle： 在 myapp/build.gradle

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

并从 myapp/app/build.gradle 中删除所有不必要的内容

dependencies {
    implementation 'com.google.firebase:firebase-core:16.0.8'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
}

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

我还删除了所有未使用的依赖项，例如 image_picker 和 firebase_ml_vision
