Firebase Dynamic Links with Flutter

Firebase Dynamic Links is a powerful feature that allows developers to create links that work seamlessly across multiple platforms, including Android, iOS, web, and desktop. In combination with Flutter, it provides a powerful toolset for developing performant apps with optimized user experiences.

In this article, we’ll explore the basics of using Firebase Dynamic Links with Flutter, including setting up a Firebase project and creating and managing Dynamic Links.

With Firebase set up, we can now start creating Dynamic Links. Dynamic Links are created on the Firebase Console and can be customized with specific settings, including:

To create a Dynamic Link, navigate to the Firebase Console and select “Dynamic Links” from the left-hand menu. From there, you can create a new Dynamic Link by clicking “Create Dynamic Link” and filling in the required information.

Once your Dynamic Link is created, you can use it in your Flutter app to direct users to specific content or actions. For example, you can create a Dynamic Link that points to a specific page in your app, and then share that link on social media or in an email campaign.

To use a Dynamic Link in Flutter, you will need to add the Firebase Dynamic Links package to your project. You can do this by adding the following line to your pubspec.yaml file:

After adding the package to your project, you can use it to handle incoming Dynamic Links in your app. Here’s an example of how to do this:

In this example, we’re using the FirebaseDynamicLinks package to listen for incoming Dynamic Links. When a link is clicked, it will launch the application if installed, otherwise take to the Google Play/App Store to prompt user to install the application. We will use the above code in the MyApp or Splash Screen (in other words, the first screen that will trigger when an application is launched). initDynamicLinks() will check the link and handle the application flow accordingly.

From there, you can use the link to direct the user to specific content or actions within your app.

There are not additional settings required for this to work properly on Android, but you need to add the following intent in your AndroidManifest.xml

This can be Confirmed by opening the apple app site association file that will be hosted on the dynamic link’s domain. Like :

If iOS Configuration is properly set up, then you will see a page displaying your app’s App Store ID and bundle ID . Like :

Creating a dynamic link from Firebase Console is pretty simple, but sometimes we need to generate shareable links dynamically using user’s input which can’t be done from the Firebase Console because we can’t give access of the Console to everyone. So there is a pretty simple solution to generate that links using mobile applications. The example of the codes are below, you can customize it in any way of your requirements.

Note: Please keep in mind that Firebase Dynamics Links currently works with Android & iOS. You can’t use this on other platforms.

In conclusion, Firebase Dynamic Links are a valuable addition to any Flutter developer’s toolkit, allowing for the creation of links that work seamlessly across multiple platforms with optimized user experiences. By following the steps outlined in this article, developers can set up their Firebase project, create and manage Dynamic Links, and integrate them into their Flutter app to direct users to specific content or actions. With the power of Firebase Dynamic Links and Flutter, developers can create performant apps with seamless user experiences, ultimately improving user engagement and satisfaction.
