when i remove this package then i can build apk . i struck in this error from 2 days now finally resolve by remove this package.

[andresperezmelo]

The error is because the latest version of the plugin is updated with kotlin 1.8.0 and your project has kotlin 1.7.10

• Update your kotlin version to 1.8.0

Go to the flutter project, and in the gradle in the path myproyect/android/build.gradle and in the line of code inside the buildscript there should be a variable ext.kotlin_version = '1.7.10' update a ext.kotlin_version = '1.8.0'

The final code should look like this

buildscript {
    ext.kotlin_version = '1.8.0' //here
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.1.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" //here
    }
}

Or you can use an older version of the plugin
