Flutter集成Firebase时Android构建失败问题求助

集成Firebase后，Android端构建失败，但Web构建无异常，错误日志如下：

ERROR:D8: com.android.tools.r8.kotlin.H
ERROR:D8: com.android.tools.r8.kotlin.H
ERROR:D8: com.android.tools.r8.kotlin.H

FAILURE: Build failed with an exception.

已将SHA-1证书添加到Firebase，该因素已排除。怀疑问题出在Gradle版本或Firebase版本，但无法确定。修改minSdk和targetSdk版本后问题依旧，代码在其他电脑可正常运行，推测是本地Android Studio配置问题。

当前配置文件 #

android/app/build.gradle

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
}

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

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

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

android {
    namespace "com.example.censeo"
    compileSdk flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

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

    defaultConfig {
        // TODO: Specify your own unique Application ID
        applicationId "com.example.censeo"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

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

flutter {
    source '../..'
}

dependencies {}

android/build.gradle

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

已尝试的解决方案 #

尝试启用MultiDex，但问题未解决，修改后的android/app/build.gradle相关代码如下：

defaultConfig {
        applicationId "com.example.censeo"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    buildTypes {
        release {
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'com.android.support:multidex:2.0.1'
}
