Development Overview
You need to install Flutter and Dart plugin in IDE and I assume that you have prior knowledge about the Flutter and Dart.
Hardware Requirements
A computer (desktop or laptop) running Windows 10.
A Huawei phone (with the USB cable), which is used for debugging.
Software Requirements
Java JDK 1.7 or later.
Android studio software or Visual Studio or Code installed.
HMS Core (APK) 4.X or later.
Integration process
Step 1: Create Flutter project.
Step 2: Add the App level gradle dependencies.
Choose inside project Android > app > build.gradle.
apply plugin: 'com.android.application'
apply plugin: 'com.huawei.agconnect'
Root level gradle dependencies
maven {url 'https://developer.huawei.com/repo/'}
classpath 'com.huawei.agconnect:agcp:1.4.1.300'
Step 3: Add the below permissions in Android Manifest file.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="com.huawei.appmarket.service.commondata.permission.GET_COMMON_DATA"/>
Step 4: Download flutter plugins
Step 5: Add downloaded file into parent directory of the project. Declare plugin path in pubspec.yaml file under dependencies.
Add path location for asset image.
