Question

您好，我通过使用flutter完成了我的第一个简单应用程序。我想将我的应用注册到Playstore中，因此我尝试通过阅读Flutter文档使其与文件捆绑在一起。

Flutter版本：1.12.13 + hotfix.5
Dart版本：2.7.0
java（jdk）版本：1.8.0_241（我已经安装了Java 11，但是昨天删除了它并安装了Java 8）
Java二进制文件位于：C：\ Program Files \ Android \ Android Studio \ jre \ bin \ java

我创建了key.jks文件，并按照flutter文档中的说明替换了build.gradle文件中的代码。这是我的build.gradle文件。

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

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 "co.my.everytime_quizz"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

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

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

但是当我运行 flutter build appbundle 时，出现错误。

错误说这部分（ def flutterRoot = localProoperties.getProperty（'flutter.sdk'））对此消息有问题

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not get unknown property 'localProperties' for project ':app' of type org.gradle.api.Project
.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more l
og output. Run with --scan to get full insights.

但是文档没有说明如何更改line7〜line20。

当我运行 flutter doctor --android-licenses 时，

A newer version of the Android SDK is required. To update, run:
C:\Users\zxaq1\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

所以我尝试了它所说的内容（...... \ sdkmanager --udpate），此错误出现了

Error: Could not find or load main class '-Dcom.android.sdklib.toolsdir=c:\Users\zxaq1\AppData\Local
\Android\Sdk\tools\bin\\..

有人说这与某个路径问题有关，但我不知道如何解决。我的主要问题是什么？如何解决这两个问题？
