update your kotlin plugin in the gradle file to 1.3.0

I had to upgrade my kotlin version to something later - I chose 1.3.60 and my gradle version to 3.5.2 in my android-level build.gradle:

// android/build.gradle
buildscript {
    ext.kotlin_version = '1.3.60'
    repositories {
        google() // Google's Maven repository
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.3' // Google Services plugin
    }
}

I then had also to upgrade my gradle distribution url:

// android/gradle/wrapper/gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

I was able to successfully flutter run after changing these.
