The team behind AWS Amplify Flutter is excited to announce the release of version 1.0.0, which enhances cross-platform application development by introducing support for web and desktop environments. With this update, developers can now target six platforms—iOS, Android, Web, Linux, MacOS, and Windows—using a single codebase. This version includes not only the Amplify libraries but also a completely revamped Flutter Authenticator UI library, developed in Dart, ensuring a uniform user experience across all platforms.

In this article, we’ll guide you through the process of creating a budget tracking application, highlighting key steps along the way:

1. Initiate a new Flutter application and configure it for iOS, Android, and Web.
2. Implement user registration and login with the Authenticator UI library in just a few minutes.
3. Create and manage budget entries.
4. Attach images to your budget entries.

Prerequisites:

• Flutter SDK version 3.3.0 or later.
• An AWS Account with Amplify CLI set up. For guidance, refer to this documentation.

Setting Up Your App and Adding Amplify Libraries

To kick things off, create a new Flutter app and integrate the Amplify Flutter libraries.

In your terminal, run:

flutter create budgetapp

Navigate to your app’s directory using:

cd budgetapp

Next, initialize your Amplify application:

amplify init

Provide a name for your Amplify project, accept the default configurations, choose your AWS profile, and let the Amplify CLI handle the setup. Once completed, you should see a confirmation message stating, “Your project has been successfully initialized and connected to the cloud!”

Now you can start adding the necessary backend resources for your application, beginning with Authentication and API. Use the command:

amplify add api

Follow the prompts in the CLI to set up the GraphQL API endpoint and your Authentication resources. Remember to adjust the authorization mode to “Cognito user pools,” which utilizes Amazon Cognito for user data access authorization.

Once you’ve configured your API, you can set up your data schema. This schema will ensure that logged-in users can only modify their own budget entries.

After adding the necessary storage resources, such as an S3 bucket for file retrieval, run:

amplify push

This command pushes all your locally added Amplify resources to your backend. Following the deployment, you’ll gain access to generated models that assist in data interaction.

To finish setting up, update your pubspec.yaml file with the required dependencies for your app.

Now, you are ready to write the code that will manage budget entries and image attachments. Amplify Flutter provides a ready-to-use UI component for user registration and login, which streamlines the authentication process. Once users authenticate, they are seamlessly redirected to the designated widget.

In the lib/main.dart file, replace it with the necessary code to initialize the Amplify libraries.
