Bug report

Could not find method platform() for arguments [com.google.firebase:firebase-bom:25.3.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.Def
aultDependencyHandler.
I recently added a firebase_messaging plugin to integrate Firebase Notifications. For android, It works fine before and when I made some changes for iOS It's crashing. I won't even be able to build the apk file. I'm not sure what's causing this error but some documentation shows it's because of the Gradle version and I did upgrade to the recent version but still I'm getting this error.

My Gradle file

android/app/gradle:

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'

Whenever I run >flutter build apk --release

My terminal log will be like:

You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

Hi @bjoffficial
Please use classpath 'com.android.tools.build:gradle:3.5.0' & classpath 'com.google.gms:google-services:4.3.3' and try again

If the problem persists, Can you please provide your flutter doctor -v logs, and a minimal complete reproducible code sample
Thank you

Hi, same issue with dependencies suggested by you. flutter channel beta

[jaween]

I had the same problem as @bjoffficial, following @TahaTesser's suggestion, for me the solution was:
Upgrade the Android Gradle plugin to 3.5.0
Upgrade the Google Services plugin to 4.3.3
Upgrade Gradle to 5.4.1 (the required Gradle version for this Android Gradle plugin version)

flutter doctor -v output (click to expand)

I'm using firebase_crashlytics 0.2.0/ firebase_core 0.5.0.

Upgrading gradle to 5.4.1 and using classpath 'com.android.tools.build:gradle:3.5.0' resolved this.

As @Renesanse and @jaween mention. Note: I am not using Google Services plugin so I didn't need to upgrade it.

[RathaIct]

Add cloud_firestore in pubspec.yaml
It work for me.

Same issue

[russellwheatley]

As far as I can tell, this isn't an issue with the core package, and looks like a configuration problem with the application.
