Build a Flutter Mobile App Using AWS Amplify - Part 1

Create a trip planner app for iOS and Android

Overview

In this how-to guide, the first part of a two-part series, you will create a cross-platform Flutter mobile app using AWS Amplify. The app is a trip planner where users can create a trip and set its name, destination, and dates. Additionally, they can upload a banner image for the trip.

In the second guide of this series, you will add new features to the app, such as adding activities for the trips using a nested data model and creating the user's profile data using an Amplify function.

What you will accomplish

This how-to guide will walk you through the steps to create an app to help users plan trips. You will:

  • Create a Flutter app using the terminal and structure its folders using the Feature-First approach where you will create a folder for every app’s feature.

  • Use the Amplify CLI to create the Amplify backend for this app

  • Add Amplify authentication capabilities to your app and use the Amplify Authenticator UI library

  • Create a data model for the trips and use the GraphQL API to synchronize to the Amplify backend

  • Add Amplify storage to your app to enable users to upload an image for their trips

Prerequisites

  • An AWS account: If you don't already have an account, follow the Setting Up Your AWS Environment tutorial for a quick overview.

  • Install and configure the Amplify CLI.

  • Install and configure Flutter.

  • A text editor combined with Flutter’s command-line tools. For this guide we will use VSCode, but you can use your preferred IDE.
