我正在使用Windows 11机器和学习Flutter的第一次，我使用它没有Android Studio.我已经安装和手动设置Android SDK.添加SDK到路径.做了一个ANDROID_SDK_ROOT环境变量.使用sdkmanager我已经安装了“构建工具;33.0.1”“平台;android-33”“platform-tools”.我已经添加flutter sdk，platform-tools到path.
我已经手动安装了Gradle版本8.0.2并将其添加到路径中。
现在我打开VS Code，打开命令面板，选择Flutter：New Project，然后选择Application。
我在bash终端中运行“flutter run”，但收到以下错误：this is the error I get
以下是我的Gradle版本：gradle version 8.0.2
Flutter Doctor输出：I am using flutter without android studio
我已经安装了jdk版本19.0.2并将其添加到路径中。在环境中添加了JAVA_HOME变量。
我尝试在www.example.com文件中更改gradle的版本gradle-wrapper.properties：Before the version was gradle-7.5-all.zip, so I simply changed it to gradle-8.0.2-all.zip, matching the one installed on my machine
之前的版本是gradle-7.5-all.zip，所以我只是将其更改为gradle-8.0.2-all.zip，与我机器上安装的版本相匹配。因此，在我的.gradle文件夹中有两个子文件夹，分别是7.5和8.0.2。
我已经尝试删除此文件夹并重新编译它，但它仍然不起作用。
我已经在网上搜索并尝试了多种解决方案。我运行了flutter clean，flutter pub get等。等等。但似乎没有一个工作。我可以尝试下一步吗？
下面是我的root/android/app/build.gradle脚本：

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 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 (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.sampleapp"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    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 "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

我尝试了互联网上的许多解决方案，但似乎没有一个有效。
