Firebase Cloud Messaging for Flutter #

Clone of official Package #

A Flutter plugin to use the Firebase Cloud Messaging (FCM) API.

With this plugin, your Flutter app can receive and process push notifications as well as data messages on Android and iOS. Read Firebase's About FCM Messages to learn more about the differences between notification messages and data messages.

For Flutter plugins for other Firebase products, see FlutterFire.md.

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and Pull Requests are most welcome!

Usage #

To use this plugin, add firebase_messaging as a dependency in your pubspec.yaml file.

Getting Started #

Check out the example directory for a sample app using Firebase Cloud Messaging.

Android Integration #

To integrate your plugin into the Android part of your app, follow these steps:

Using the Firebase Console add an Android app to your project: Follow the assistant, download the generated google-services.json file and place it inside android/app. Next, modify the android/build.gradle file and the android/app/build.gradle file to add the Google services plugin as described by the Firebase assistant.
(optional, but recommended) If want to be notified in your app (via onResume and onLaunch, see below) when the user clicks on a notification in the system tray include the following intent-filter within the <activity> tag of your android/app/src/main/AndroidManifest.xml:

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

iOS Integration #

To integrate your plugin into the iOS part of your app, follow these steps:

Generate the certificates required by Apple for receiving push notifications following this guide in the Firebase docs. You can skip the section titled "Create the Provisioning Profile".
Using the Firebase Console add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner. Don't follow the steps named "Add Firebase SDK" and "Add initialization code" in the Firebase assistant.
In Xcode, select Runner in the Project Navigator. In the Capabilities Tab turn on Push Notifications.
Remove the use_frameworks! line from ios/Podfile (workaround for flutter/flutter#9694).
Follow the steps in the "Upload your APNs certificate" section of the Firebase docs.

Dart/Flutter Integration #

From your Dart code, you need to import the plugin and instantiate it:

import 'package:firebase_messaging/firebase_messaging.dart';

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();

Next, you should probably request permissions for receiving Push Notifications. For this, call _firebaseMessaging.requestNotificationPermissions(). This will bring up a permissions dialog for the user to confirm on iOS. It's a no-op on Android. Last, but not least, register onMessage, onResume, and onLaunch callbacks via _firebaseMessaging.configure() to listen for incoming messages (see table below for more information).

Receiving Messages #

Messages are sent to your Flutter app via the onMessage, onLaunch, and onResume callbacks that you configured with the plugin during setup. Here is how different message types are delivered on the supported platforms:

	App in Foreground	App in Background	App Terminated
Notification on Android	`onMessage`	Notification is delivered to system tray. When the user clicks on it to open app `onResume` fires if `click_action: FLUTTER_NOTIFICATION_CLICK` is set (see below).	Notification is delivered to system tray. When the user clicks on it to open app `onLaunch` fires if `click_action: FLUTTER_NOTIFICATION_CLICK` is set (see below).
Notification on iOS	`onMessage`	Notification is delivered to system tray. When the user clicks on it to open app `onResume` fires.	Notification is delivered to system tray. When the user clicks on it to open app `onLaunch` fires.
Data Message on Android	`onMessage`	`onMessage` while app stays in the background.	not supported by plugin, message is lost
Data Message on iOS	`onMessage`	Message is stored by FCM and delivered to app via `onMessage` when the app is brought back to foreground.	Message is stored by FCM and delivered to app via `onMessage` when the app is brought back to foreground.

Additional reading: Firebase's About FCM Messages.

Sending Messages #

Refer to the Firebase documentation about FCM for all the details about sending messages to your app. When sending a notification message to an Android device, you need to make sure to set the click_action property of the message to FLUTTER_NOTIFICATION_CLICK. Otherwise the plugin will be unable to deliver the notification to your app when the users clicks on it in the system tray.

For testing purposes, the simplest way to send a notification is via the Firebase Console. Make sure to include click_action: FLUTTER_NOTIFICATION_CLICK as a "Custom data" key-value-pair (under "Advanced options") when targeting an Android device. The Firebase Console does not support sending data messages.

Alternatively, a notification or data message can be sent from a terminal:

DATA='{"notification": {"body": "this is a body","title": "this is a title"}, "priority": "high", "data": {"click_action": "FLUTTER_NOTIFICATION_CLICK", "id": "1", "status": "done"}, "to": "<FCM TOKEN>"}'
curl https://fcm.googleapis.com/fcm/send -H "Content-Type:application/json" -X POST -d "$DATA" -H "Authorization: key=<FCM SERVER KEY>"

Remove the notification property in DATA to send a data message.

4.0.1+1 #

Log messages about automatic configuration of the default app are now less confusing.

4.0.0 #

Breaking Change Update message structure for onMessage to match onLaunch and onResume

3.0.1 #

Log a more detailed warning at build time about the previous AndroidX migration.

3.0.0 #

Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

This was originally incorrectly pushed in the 2.2.0 update.

2.2.0+1 #

Revert the breaking 2.2.0 update. 2.2.0 was known to be breaking and should have incremented the major version number instead of the minor. This revert is in and of itself breaking for anyone that has already migrated however. Anyone who has already migrated their app to AndroidX should immediately update to 3.0.0 instead. That's the correctly versioned new push of 2.2.0.

2.2.0 #

BAD. This was a breaking change that was incorrectly published on a minor version upgrade, should never have happened. Reverted by 2.2.0+1.
Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

2.1.0 #

Adding support for deleteInstanceID(), autoInitEnabled() and setAutoInitEnabled().

2.0.3 #

Removing local cache of getToken() in the dart part of the plugin. Now getToken() calls directly its counterparts in the iOS and Android implementations. This enables obtaining its value without calling configure() or having to wait for a new token refresh.

Use boolean values when checking for notification types on iOS.

2.0.1 #

Bump Android dependencies to latest.
