👋 Welcome! In this tutorial, you will:

• Setup your Flutter development environment
• Add the Amplify Flutter Library dependencies
• Create a basic app that records an analytics event
• Use Amplify CLI to setup your AWS backend resources

• Install Flutter version 1.20.0 or higher (make sure you are using a stable version of flutter)

• Setup your IDE

  This tutorial assumes you are using AndroidStudio to develop your app.

• Install the Amplify CLI by running:

  NPMcURL (Mac and Linux)cURL (Windows)

  npm install -g @aws-amplify/cli
  npm install -g @aws-amplify/cli

  Note: Because we’re installing the Amplify CLI globally, you might need to run the command above with sudo depending on your system policies.

  curl -sL https://aws-amplify.github.io/amplify-cli/install | bash && $SHELL
  curl -sL https://aws-amplify.github.io/amplify-cli/install | bash && $SHELL

  curl -sL https://aws-amplify.github.io/amplify-cli/install-win -o install.cmd && install.cmd
  curl -sL https://aws-amplify.github.io/amplify-cli/install-win -o install.cmd && install.cmd

• Sign up for an AWS account

  If you don’t already have an AWS account, you’ll need to create one in order to follow the steps outlined in this tutorial.

  Create AWS Account

  There are no upfront charges or any term commitments to create an AWS account and signing up gives you immediate access to the AWS Free Tier.

1. Create a new project using Flutter CLI:

    flutter create todo
    flutter create todo

2. Or using Android Studio. Select + Start a new Flutter project.

   

3. In Select a Project Template, select Flutter Application. Press Next.

   

1. Next, configure your project:

   • Enter todo in the Name field
   • Make sure your Flutter SDK path is set correctly to where it is installed on your machine
   • Press Next. On the next screen, press Finish.

   

Android Studio will open your project with a tab opened to main.dart

1. Modify your Podfile to target iOS platform 11.0 or higher. Within your project open ios/Podfile and change the second line to be `platform :ios, ‘11.0’.
2. Modify your AndroidManifest.xml to target minSDK 21 or higher. Within your project open android/app/src/main/AndroidManifest.xml and change the line starting with minSdkVersion to be minSdkVersion 21.

You now have an empty Flutter project into which you’ll add Amplify in the next steps.

Amplify for Flutter is distributed via pub.dev.

1. Open your app‘s pubspec.yaml and add the following 3 dependencies below the line “sdk:flutter”.

dependencies:
  flutter:
    sdk: flutter

  amplify_flutter: '<1.0.0'
  amplify_auth_cognito: '<1.0.0'
  amplify_analytics_pinpoint: '<1.0.0'
dependencies:
  flutter:
    sdk: flutter

  amplify_flutter: '<1.0.0'
  amplify_auth_cognito: '<1.0.0'
  amplify_analytics_pinpoint: '<1.0.0'

1. Run Flutter Pub Get

   Android Studio requires you to sync your project with your new configuration. To do this, you can click Flutter in the notification bar above the file editor.

   

   Alternatively, you can open a terminal window, cd into your project’s root directory (where your pubspec.yaml is) and run:

    flutter pub get 
    flutter pub get 

   When complete, you will see Process finished with exit code 0 in the output of the Messages tab at the bottom of your screen.

   

You are ready to start building with Amplify! 🎉
