How to add authentication to your FlutterFlow project?

Adding authentication to your FlutterFlow project can greatly enhance the security of your app by ensuring only authorized individuals have access. Here is a comprehensive guide on how to achieve that:

Step 1: Create a Flutter Flow Project

If you have not already, create a new FlutterFlow project. From the FlutterFlow home page, click on the New Project button. Enter an appropriate name and description for your project in the provided text boxes. Click the Create button, and a fresh project will be created.

Step 2: Navigate to the Navigation Sidebar

Once your project is open in the editor, look for the Navigation sidebar on the left side of the screen.
Within the sidebar, find and click the Authentication button.

Step 3: Enable Authentication

On the appearing pane, you will notice an Enable Authentication toggle. Click on this toggle to activate it. You will notice the previously greyed out fields such as Sign Up, Log In, Forgot Password, and Reset Password becoming active.

Step 4: Configure the Authentication Settings

You can customize the authentication process according to your needs.

• Sign Up: If you want your app's users to sign up with their own login credentials, click the Sign Up+ field, then select Email/Password under the methods section that appears.
• Log In: Click on Log In, and inside that toggle the Email/Password button to on.
• Forgot Password & Reset Password: If you'd like your users to be able to reset their passwords, click on Forgot Password, and under the action settings for Forgot Password, add a reset password page. Do the same for Reset Password.

Step 5: Adding OAuth providers

If you want your users to sign up or log in using an OAuth provider (such as Google, Facebook, Apple, or others), you will add this in the same area. Click on the + button, then select the provider of your choice.
Note that for these providers, you'll need to set up an app with that provider, get the Client ID and Client Secret or Key, and input them into the provided input fields for respective providers.

Step 6: Saving Changes

One final step! Now, ensure you save all your changes. To do so, navigate to the top right corner of your screen and click the Save Project button.

Further Steps: Adding UI elements for Authentication

Handling the actual login and sign up flow in the app is through the Button or TextButton widgets on pages you create. For example:

• On your login page, you can add a Button Widget. Click the button to edit it and under the Actions tab, select Login with Email under the Type dropdown. Input the relevant parameters from your authentication setup in Step 4.
• On your sign up page, set the Button action to Create Account. Don't forget to configure the error screen and success screen.
• Password reset works similarly. Set a Button action on the user input email screen to Send Password Reset Email and on the subsequent page to Reset Password.

So there it is! You've successfully added authentication to your FlutterFlow project. As you continue to develop your project, remember to customize these actions and screens to fit the look and feel of your app as well as equip it with error handling. Happy FlutterFlow-ing!
