Introduction
On this article, we will probably be integrating Huawei Distant Configuration service, Account Equipment in Flutter DietApp. Flutter plugin supplies easy and handy technique to expertise authorization of customers. Flutter Account Plugin permits customers to connect with the Huawei ecosystem utilizing their Huawei IDs from the completely different gadgets similar to mobiles telephones and tablets, added customers can login shortly and conveniently sign up to apps with their Huawei IDs after granting preliminary entry permission.
We can even be taught to combine Huawei Crash Service on this software. It’s a accountability of the developer to construct crash free i.e. surprising exit of software, it is vitally tough to search out the reason for the crash in large software code base. This surprising crash makes app customers annoying and will result in enterprise loss and cut back market worth of the product and the corporate. To keep away from such crashes Huawei supplies Crash service which makes developer to search out the crash and reason for surprising exit of the appliance in AG-console.
Crash SDK supplies quite simple and developer needn’t code a lot to implementation crash service. It’s also possible to obtain the detailed crash report each time required.
Distant Configuration is a service offered by Huawei. It supplies cloud-based companies. When you combine the shopper SDK, your app can periodically fetch parameter values from the cloud. The service checks whether or not the parameter that your app tries fetching has an on-cloud worth replace and returns the brand new worth in that case. Based mostly on the parameter values fetched, you possibly can implement service processing logic to vary behaviour or look of your app. On this pattern i.e. DietApp, we’re fetching the Private Train knowledge utilizing Distant Configuration service by AppGallery.

Improvement Overview
It’s essential set up Flutter and Dart plugin in IDE and I assume that you’ve prior information concerning the Flutter and Dart.
{Hardware} Necessities
A pc (desktop or laptop computer) working Home windows 10.
Android cellphone (with the USB cable), which is used for debugging.
Software program Necessities
Java JDK 1.7 or later.
Android studio software program or Visible Studio or Code put in.
HMS Core (APK) 4.X or later.
Integration course of
Step 1: Create Flutter venture.
Step 2: Add the App stage gradle dependencies. Select inside venture Android > app > construct.gradle.
apply plugin: 'com.android.software'
apply plugin: 'com.huawei.agconnect'
Root stage gradle dependencies
maven {url 'https://developer.huawei.com/repo/'}
classpath 'com.huawei.agconnect:agcp:1.5.2.300'
Step 3: Add the under permissions in Android Manifest file.<uses-permission android:identify="android.permission.INTERNET" />
Step 4: Add downloaded file into dad or mum listing of the venture. Declare plugin path in pubspec.yaml file underneath dependencies.
Add path location for asset picture.

Consequence
Methods and Suggestions
Make it possible for downloaded plugin is unzipped in dad or mum listing of venture.
Makes certain that agconnect-services.json file added.
Make certain dependencies are added yaml file.
Run flutter pug get after including dependencies.
Make it possible for service is enabled in agc.
Makes certain photos are outlined in yaml file.
Make certain parameter added in agc is json format.
Conclusion
On this article, now we have learnt find out how to combine Huawei Distant Configuration service, Account equipment, Crash equipment flutter DietApp. As soon as Account equipment built-in, customers can login shortly and conveniently sign up to apps with their Huawei IDs after granting preliminary entry permission. Push equipment lets you ship push notification to person system in actual time, you possibly can see the push notification within the consequence half. Huawei Crash service which supplies builders to shortly detect, find and repair the crash or surprising exit of software. Therefore improves stability and reliability of software. With the assistance of Distant Configuration service we’re fetching the Private Train knowledge from the cloud.
Thanks a lot for studying. I hope this text lets you perceive the combination of Huawei Distant Configuration, Account equipment and Crash equipment in flutter DietApp.
