Flutter Onesignal Could not resolve com.google.firebase:firebase-messaging

I'm trying to run my flutter application after added onesignal_flutter: ^3.2.8 on my pubspec.yaml. I got this error:

Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Could not resolve com.google.firebase:firebase-messaging:{require [19.0.0, 22.0.99]; prefer 22.0.0}.

Add the following lines to your android/app/build.gradle

    buildscript {
      repositories {
         // ...
         mavenCentral()
      }
      dependencies {
        // ...
        // OneSignal-Gradle-Plugin
       classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.10, 0.99.99]'
      }
    }

   apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

You can also refer to One Signal documentation for more info.
