Flutter在发行版apk / bundle上的firebase上无法正常使用

Question

[当我执行flutter run时，我的应用程序可以在Firebase（cloud_firestore）上正常运行，但是只要执行以下命令之一，就可以：flutter build apk --release要么flutter build appbundle --target-platform android-arm,android-arm64,android-x64我的应用无法在cloud_firestore上正常使用。它不执行CRUD操作。

pubspec.yaml（插件）：

  google_sign_in: 4.5.1
  firebase_auth: 0.16.1
  firebase_core: ^0.4.0+8
  firebase_analytics: ^5.0.14
  cloud_firestore: ^0.13.6

app / build.gradle：

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 = '15'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '15.0'
}

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

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    compileSdkVersion 28

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

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        applicationId "com.tomeruby.iusefully"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
        // ndk {
        //     abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
        // }
    }

    signingConfigs {
       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
           storePassword keystoreProperties['storePassword']
       }
    }

    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.release
            multiDexEnabled true
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    // implementation 'com.google.firebase:firebase-core:16.0.5'
    // implementation 'com.google.firebase:firebase-analytics-impl:16.2.3'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

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

如果您需要更多信息，请告诉我。在此先感谢：D

Answer 1

尝试更改

classpath 'com.google.gms:google-services:4.3.0'

在您的工程gradle.build到]中>
classpath 'com.google.gms:google-services:3.2.1'
和gradle.properties添加
android.useAndroidX=true
android.enableJetifier=true

一旦清除构建，如果没有问题，请再次调试apk，然后再次构建发行版apk。它应该可以正常工作。
