Answer 1

1. Add Dependency

For sending push notifications we use a plugin called firebase_messaging…

https://pub.dev/packages/firebase_messaging

Open your pubspec.yaml file and add this dependency

dependencies: firebase_messaging: ^6.0.9

2. Firebase Account

Make sure you have a firebase account before proceeding.
In the next step, you should be able to download the google-services.json file.

After downloading the file, make sure to copy it inside the app/ folder of your Android project.

3. Android Manifest

ADD

<intent-filter>
  <action android:name="FLUTTER_NOTIFICATION_CLICK" />
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Add these lines to [project]/android/build.gradle

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath 'com.google.gms:google-services:4.3.3'
}

Add these lines to [project]/android/app/build.gradle

 dependencies {
   implementation fileTree(dir: "libs", include: ["*.jar"])
   implementation 'androidx.appcompat:appcompat:1.1.0'
   implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
   implementation 'com.google.firebase:firebase-messaging:20.2.3'
   implementation 'com.google.firebase:firebase-analytics:17.4.4'

   // Add the SDK for Firebase Cloud Messaging
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'androidx.test.ext:junit:1.1.1'
   androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

 }


 apply plugin: 'com.google.gms.google-services'

DONE

If you're trying to put messages on the lock screen, make sure you're sending a "notification" message type, rather than a "data" message that will be delivered to the running app. You can learn more about the different types of Firebase messages in the Firebase developer guide.

Push notifications in Flutter can be particularly difficult because you have to do twice the work to get them working with Android & iOS' particular implementations (both of which are, of course, quite different).

I've been building the OneSignal SDK for flutter. It will be ready within a few days. We work pretty hard to simplify push notifications as much as possible, and it's easy to use our SDK in a GDPR compliant way.

The repo is here (https://github.com/OneSignal/OneSignal-Flutter-SDK), it's open source and we welcome contributions from anyone. It acts as a wrapper on top of the native Android & iOS OneSignal SDK's.
