无法建立发布版APK

flutter

我目前正在尝试使用Flutter在Windows上构建签名发行的APK。我已经执行了flutter网站上的文档中概述的任务。当我运行build命令时，这是我得到的输出。似乎是在Firebase插件周围。有任何想法吗？

pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  firebase_auth: 0.4.0
  firebase_database: ^0.3.0

事实证明，处理此问题的最佳方法是在中进行以下更改android/app/build.gradle：

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.3'
    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }
    // This is the main section that I've updated
    // to get the release APK to build
    buildTypes {
        release {
            profile {
                matchingFallbacks = ['debug', 'release']
            }
            signingConfig signingConfigs.release
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

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

通过此更改，我能够构建发行版APK。
