Flutter Firebase In-App Messaging: How To Examples

Introduction

Firebase In-App Messaging is a powerful tool provided by Firebase that enables you to engage users directly within your Flutter application. It allows you to create and display targeted, personalized messages to your users, increasing user engagement and retention.

In this tutorial, we will explore various examples of using Firebase In-App Messaging in a Flutter application. We will cover installation, configuration, and implementation of different messaging scenarios.

Prerequisites

Before we get started, make sure you have the following:

• Flutter SDK installed on your machine
• A Firebase project set up (https://console.firebase.google.com/)
• FlutterFire dependencies added to your project (https://firebase.flutter.dev/docs/installation/)

Installation

To use Firebase In-App Messaging in your Flutter project, follow these steps:

1. Open your project in the Firebase console.
2. Go to the "In-App Messaging" section.
3. Click on the "Get Started" button.
4. Select your target platform (Android, iOS, or both).
5. Follow the provided instructions to install the necessary dependencies and add the required configuration files to your project.
6. Once the installation is complete, you're ready to start using Firebase In-App Messaging in your Flutter application.

Example 1: Basic In-App Message

Let's start with a basic example of displaying a simple in-app message to the user.

import 'package:firebase_in_app_messaging/firebase_in_app_messaging.dart';

class MyApp extends StatelessWidget {
  final FirebaseInAppMessaging fiam = FirebaseInAppMessaging();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'In-App Messaging Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('In-App Messaging Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () {
              fiam.triggerEvent('example_event');
            },
            child: Text('Show Message'),
          ),
        ),
      ),
    );
  }
}

In this example, we import the firebase_in_app_messaging package and create an instance of FirebaseInAppMessaging. We then trigger an event named 'example_event' when the button is pressed.

Expected Output: When the button is pressed, the Firebase In-App Messaging system will display a message to the user based on the configured campaign.

Example 2: Customizing In-App Message Display

You can customize the appearance of in-app messages to match your application's design. Let's see how to change the background color and text color of a message.

class MyApp extends StatelessWidget {
  final FirebaseInAppMessaging fiam = FirebaseInAppMessaging();

  @override
  Widget build(BuildContext context) {
    fiam.setBackgroundColor(Colors.blue);
    fiam.setMessageTextColor(Colors.white);

    return MaterialApp(
      title: 'In-App Messaging Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('In-App Messaging Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () {
              fiam.triggerEvent('example_event');
            },
            child: Text('Show Message'),
          ),
        ),
      ),
    );
  }
}

In this example, we use the setBackgroundColor and setMessageTextColor methods to customize the background color and text color of the in-app message. We set the background color to blue and the text color to white.

Expected Output: When the button is pressed, the Firebase In-App Messaging system will display a message with a blue background and white text.

Example 3: Displaying In-App Banners

In addition to full-screen messages, Firebase In-App Messaging also supports displaying banners at the top or bottom of the screen. Let's see how to show a banner message.

class MyApp extends StatelessWidget {
  final FirebaseInAppMessaging fiam = FirebaseInAppMessaging();

  @override
  Widget build(BuildContext context) {
    fiam.setDisplayFormat(DisplayFormat.banner);

    return MaterialApp(
      title: 'In-App Messaging Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('In-App Messaging Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () {
              fiam.triggerEvent('example_event');
            },
            child: Text('Show Message'),
          ),
        ),
      ),
    );
  }
}

In this example, we use the setDisplayFormat method to set the display format to DisplayFormat.banner. This will display the in-app message as a banner at the top or bottom of the screen, depending on the device's configuration.

Expected Output: When the button is pressed, the Firebase In-App Messaging system will display a banner message at the top or bottom of the screen.

Example 4: Custom Events

You can trigger in-app messages based on custom events within your application. Let's see how to trigger a message when a specific event occurs.

class MyApp extends StatelessWidget {
  final FirebaseInAppMessaging fiam = FirebaseInAppMessaging();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'In-App Messaging Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('In-App Messaging Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () {
              // Simulate a custom event
              _simulateCustomEvent();
            },
            child: Text('Trigger Event'),
          ),
        ),
      ),
    );
  }

  void _simulateCustomEvent() {
    // Perform some actions
    // ...

    // Trigger the custom event
    fiam.triggerEvent('custom_event');
  }
}

In this example, we trigger a custom event named 'custom_event' when the button is pressed. You can replace the _simulateCustomEvent method with your own logic to trigger the event based on your application's requirements.

Expected Output: When the button is pressed, the Firebase In-App Messaging system will display a message based on the custom event 'custom_event'.

Example 5: Excluding Users

You can exclude specific users from receiving in-app messages. Let's see how to exclude a user from receiving messages.

class MyApp extends StatelessWidget {
  final FirebaseInAppMessaging fiam = FirebaseInAppMessaging();

  @override
  Widget build(BuildContext context) {
    fiam.setAutomaticDataCollectionEnabled(false);
    fiam.setMessagesSuppressed(true);

    return MaterialApp(
      title: 'In-App Messaging Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('In-App Messaging Example'),
        ),
        body: Center(
          child: RaisedButton(
            onPressed: () {
              fiam.triggerEvent('example_event');
            },
            child: Text('Show Message'),
          ),
        ),
      ),
    );
  }
}

In this example, we use the setAutomaticDataCollectionEnabled method to disable automatic data collection and the setMessagesSuppressed method to suppress all messages. This effectively excludes the user from receiving any in-app messages.

Expected Output: When the button is pressed, the Firebase In-App Messaging system will not display any message to the user.
