title: New Gradle Sync is not supported due to containing Kotlin modules using an unsupported plugin version
body: <p>I'm using android studio 3.4.1 and my Kotlin version is <code>1.3.31</code>. I have a flutter app. When trying to add <code>cloud_firestore</code> to my app I have the following issue. My android studio Kotlin version is exactly the same as <code>build.gradle</code>. Any advice?</p>
  <p>Here is the my <code>buld.gradle</code>:</p>
  <pre><code>buildscript {
      ext.kotlin_version = '1.3.31'
      repositories {
          google()
          jcenter()
      }
  
      dependencies {
          classpath 'com.android.tools.build:gradle:3.4.1'
          classpath &quot;org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version&quot;
          // for firebase
          classpath 'com.google.gms:google-services:4.2.0'
      }
  }
  </code></pre>
