本人使用 androidStudio 4.0

```android {    compileSdkVersion 28    compileOptions {        sourceCompatibility 1.8        targetCompatibility 1.8    }    defaultConfig {        applicationId "com.example.car_analyzef.host"        minSdkVersion 16        targetSdkVersion 28        versionCode 1        versionName "1.0"        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"    }    buildTypes {        profile {            initWith debug        }        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        }    }}```

```buildscript {    repositories {        google()        jcenter()    }    dependencies {        classpath 'com.android.tools.build:gradle:3.5.0'    }}allprojects {    repositories {        google()        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}```

执行下flutter clean然后在试下

  这个方法不管用，github上的方法也不行。我发现如果插件时纯flutter开发的就行，如果插件实际会调用android原生方法，这类的插件就用不了了。

  尝试将flutter版本升级到v1.17试一下。
