- How to authenticate users with the at_onboarding plugin.
A quick introduction to the at_onboarding plugin?
The at_onboarding is a plugin developed by the @ company to allow users to onboard any sign-in protocol app very quickly with their @ sign username.
An @ sign is a handle (i.e. @ alice) that functions as the users (individual) digital identity. It uses end-to-end encryption to ensure that your data is 100% owned and controlled by you.
About The @ Company
The @ Company (At Company) is a technology company that aims at creating a more human Internet where privacy is a fundamental right and everyone owns their own data.
The company uses a technology called the @ protocol to allow people to own their data and control what information they share with whom.
So let's get started
STEP 1: How to set up an @ sign account.
To create an @ sign account, go to atsign.com At the top right corner of the site, click on "Get an @ sign" to create your own @ sign username
Choose a free @ sign and click on Add to Cart
A pop will appear, click on CHECKOUT to complete the account setup
The CHECKOUT process requires your email address, enter your email address and click on the submit button.
A 4-character code will be sent to your email address, enter the 4-character code sent to your email address and click on the confirm button.
Congratulations, you have secured an @ sign username.
Step 2: How to verify your @ sign username.
To verify your @ sign username, click on Activate button.
A dialog will pop up, click on Save code, this will download your @ sign QR code.
Please note: Do not share your @ sign QR code with anyone.
Step 3: Implementing at_onboarding in our flutter app
Create your flutter app using Visual Studio, IntelliJ, or Android Studio.
Open the "pubspec.yaml" file, and install the following packages.
dependencies: at_onboarding_flutter: ^2.1.2 get_storage:
Please note: The "at_onboarding_flutter" plugin will be used for user authentication while the "get_storage" plugin will be used to store the user's @ sign username.
Open your main.dart file, and modify your source code to look like this image below:
Create a stateful widget and name it "MyApp", modify your source code to look like this image below:
The next step will be to create a dart class and it will be called "AtService", modify your source code to look like this image below:
Please note: The "AtService" has two functions which are "getAtClientPreference" and "deleteAtSign"
The "getAtClientPreference" is called whenever the user wants to login into the app while the "deleteAtSign" logs the user out of the app and removes the user's @ sign username from the app.
Up next will be to create a stateless widget with the name "DashBoard", this screen will be called after successful authentication.
Modify your source code to look like this image below:
Lastly, you need to provide an @ sign backup key, this requires downloading the @ wavi app on the Google play store or Apple store.
Please note: @ Wavi is a privacy-first mobile app developed by the @ Company.
The app helps you control what links, images, and text are visible and searchable online. Open your @ wavi app and follow the steps below to download your @ sign backup key.
Test run your app on your smartphone or emulator.
Congratulations!! you have successfully implemented the at_onboarding plugin in your flutter project.
