Couldn't sync after adding depenency to gradle in VScode - firebase

Question

I tried to configure my flutter project in order to use firebase. I added all the dependency and couldn't sync after adding the lines mentioned in the firebase to Gradle build.
How do I sync in vscode.
added depenency for firebase:
In project -> android -> app -> build.gradle :
apply plugin: 'com.google.gms.google-services'
In project -> gradle -> build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
**classpath 'com.google.gms:google-services:4.3.3'**
}
IN project -> pubspec.yaml
firebase_auth: ^0.14.0+5
Also ran flutter pub get
Error log:

When using Firebase, you need to download the google-services.json file and add it to your project:
Where do I place Googleservices.json in Flutter app in order to solve 'google-services.json is missing'
Then in the android/build.gradle, you need to add the google() maven repository:
buildscript {
repositories {
// Check that you have the following line (if not, add it):
google() // Google's Maven repository
}
dependencies {
...
// Add this line
classpath 'com.google.gms:google-services:4.3.3'
}
}
allprojects {
...
repositories {
// Check that you have the following line (if not, add it):
google() // Google's Maven repository
...
}
}
and inside android\app\build.gradle, you need to add the google-service plugin:
apply plugin: 'com.google.gms.google-services'
