    Add google() to your repositories(buildscript and allprojects sections) of app level build.gradle file. The Android Gradle plugin is located there: your_project_folder/android/build.gradle

    buildscript {
  ...
  repositories {
    google()
    mavenCentral()
  }
}

allprojects {
  repositories {
    google()
    mavenCentral()
  }
}
