我的android版本是4.0.1

这是我的 build.gradle 文件我不知道出了什么问题我将我的 jdk sdk 和 android studio 更新到了最新版本 4.1.2

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  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 from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
   compileSdkVersion 30

   defaultConfig {
       // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
       applicationId "com.example.flutterwq"
       minSdkVersion 16
       targetSdkVersion 30
       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 '../..'
}

打开 android/build.gradle 文件，检查 com.android.tools.build:gradle 的版本：

buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        ...
    }
}

缩小该版本，直到某个版本可以工作。可以从这里的插件栏中选择版本： https ://developer.android.com/studio/releases/gradle-plugin#updating-gradle

当 gradle 太旧并且 android gradle 插件太新时就会出现此问题。
