Plugin with id 'androidx.navigation.safeargs' not found

When I try to add Safe Args (Android Navigation) to my app's as following

( using this guide : https://developer.android.com/topic/libraries/architecture/navigation/navigation-pass-data ) :

apply plugin: 'com.android.application'
apply plugin: 'androidx.navigation.safeargs'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
apply plugin: 'com.google.gms.google-services'

android {...

I receive this error :

> Plugin with id 'androidx.navigation.safeargs' not found.

To add androidx.navigation.safeargsplugin follow below step's

1. classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha09"
   (latest) Add above to your Project Gradel file inside dependency block

2. Then add apply plugin: 'androidx.navigation.safeargs' to your app/Module gradle file

Just add this line in your build.gradle project level :

 classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.2.0-rc02"

Add

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha05"

In your project-level dependencies

For eg :

dependencies {
       classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha05"

}

Don't forget to add the latest version

In newer version of Android Studio 3.2+, below dependency need to add in both build.gradle file

Project-Level build.gradle

dependencies {
    classpath 'androidx.navigation:navigation-safe-args-gradle-plugin:2.3.5'
}

App-Level build.gradle

plugins {
    id 'androidx.navigation.safeargs' 
}

It appears because you are declaring it in the wrong build.gradle file. You have to place it in the build.gradle that looks like this

buildscript {
    repositories {
        google()
    }
    dependencies {
        def nav_version = "2.1.0"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
    }
}

This link explain how it is added https://developer.android.com/jetpack/androidx/releases/navigation#safe_args

as per this https://developer.android.com/jetpack/androidx/releases/navigation

Add above to your Project Gradel file inside dependency block

`classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:2.2.1`

then add apply plugin: androidx.navigation.safeargs to your app/Module gradle file

I had to add it to the top level build.gradle, not sure if you've just added it to your app level build.gradle instead
