Rita: Okay.

Me: Here is your answer for first question.

What is account kit?

To answer this question let me give introduction about account kit.

Introduction

Huawei Account Kit is a development kit and account service developed by Huawei. Easy to integrate Sign In-based functions into your applications. It save user’s long authorization period and also two factor authorization user information is very safe. Flutter account kit plugin allows users to connect with Huawei Ecosystem using Huawei IDs. It supports both mobiles and tablets. User can sign any application from Huawei account.

Rita: Awesome introduction (@Reader its self-compliment. If you have any questions/compliments/comments about account kit in flutter. I’m expecting it in comments section.)

Me: I hope now you got answer for what is account kit?

Rita: Yes, I got it.

Me: Let’s move to next question

What is the benefit of account kit?

Me: Before answering this question, let me ask you one question. How do you sign up for application?

Rita: Traditional way.

Me: Traditional way means?

Rita: I’ll ask user information in the application.

Me: Okay, let me explain you one scenario, if you are referring same thing let me know.

Rita: Fine

Me: Being a developer, what we usually do is we collect user information in sign up screen manually. User first name, last name, email id, mobile number, profile picture etc. These are the basic information required to create account. Let me share you one screen.

Me: This is how you ask for sign up right?

Rita: Exactly you are right, I’m referring same things.

Me: See in this traditional way user has to enter everything manually it is very time consuming. You know nowadays users are very specific about time. User needs everything in one click for that, being a developer we need to fulfill user requirement. So Huawei built a Flutter plugin for account kit to overcome the above situation.

Me: Now you got the problem right?

Rita: Yes.

Me: So, to avoid above situation you can sign up using Huawei account kit and get user information in one click more over user information is safe.

Me: I hope I have answered your question what is the benefit of account kit?

Rita: Yes

Me: Now let me explain about features of Account Kit.

Features of Account kit

1. Sign in

2. Silent sign in

3. Sign out

4. Revoke authorization.

Me: Now let’s move to next question.

How much time it takes to integrate in flutter?

Me: this is very simple question it hardly takes 10 minutes.

Rita: Oh is it? It means Integration will be very easy.

Me: Yes, you are clever.

Rita: ha ha ha. I’m not clever Huawei made it very easy, I just guessed it.

Me: Okay, are you getting bored?

Rita: No, why?

Me: If you are bored, I just wanted to crack a joke.

Rita: Joke? That’s too from you? No buddy because I’ll get confuse where to laugh and you know sometimes I don’t even get you have finished your joke.

Me: Everybody says the same thing.

Rita: Then imagine, how bad you in joke.

Me: Okay Okay, lets come back to concept (In angry).

Rita: Don’t get angry man I’m in mood of learning not in mood of listening joke.

Me: Okay, let’s move to next question.

Me: Yeah.

Rita: Hey you did not explain more about features of Account kit.

Me: Oh, yeah I forgot to explain about it, let me explain. As you already know what are features, so let me explain one by one.

Sign In: The signIn method is used to obtain the intent of the HUAWEI ID sign-in authorization page. It takes an HmsAuthParamHelper object as a parameter which is optional. This parameter allows you to customize the sign-in request. When this method is called, an authorization page shows up. After a user successfully signs in using a HUAWEI ID, the HUAWEI ID information is obtained through the HmsAuthHuaweiId object.

Me: Add button or image in application and on tap of button use the below code.

..setProfile()

..setEmail()

..setScopeList([HmsScope.openId, HmsScope.email, HmsScope.profile])

..setRequestCode(8888);

try {

final HmsAuthHuaweiId accountInfo =

await HmsAuthService.signIn(authParamHelper: authParamHelper);

setState(() {

var accountDetails = AccountInformation(accountInfo.displayName,

accountInfo.email, accountInfo.givenName, accountInfo.familyName, accountInfo.avatarUriString);

Navigator.push(

context,

MaterialPageRoute(

),

));

print("account name: " + accountInfo.displayName);

});

} on Exception catch (exception) {

print(exception.toString());

print("error: " + exception.toString());

}

}

Silent Sign In: The silentSignIn method is used to obtain the HUAWEI ID that has been used to sign in to the app. In this process, the authorization page is not displayed to the HUAWEI ID user. The method takes an HmsAuthParamHelper object as a parameter which is optional, returns an HmsAuthHuaweiId object upon a successful operation.

Navigator.pushReplacement(context, route);

} else {

print('Login_provider:signOut failed');

}

}
