CodePudding user response：

Uninstall JAVA version 11 and install 1.8 version it worked for me hope it will work for you too.

CodePudding user response：

Can you show this files (C:\flutter_application_1\android\app\build.gradle) content along with gradle.properties ?

In your project/android/app/build.gradle there will be few lines like below:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

if you want to use java 11 , install java 11 and try adding these lines and replacing the above configuration:

compileOptions {         
     sourceCompatibility JavaVersion.VERSION_11         
     targetCompatibility JavaVersion.VERSION_11   
}  

kotlinOptions {         
     jvmTarget = '11'     
}

and do vice-versa for otherwise
