Flutter Build Fails with HMS Integration: com.huawei.agconnectclouddb.objecttypes Package Not Found

[dev-munashe]

I am working on integrating Huawei Mobile Services (HMS) into my existing Flutter application by following the official documentation.

Here is what I have done so far:

1. I have created a project in AppGallery Connect and set up an Android app.

2. Downloaded the agconnect-services.json configuration file and placed it in the android/app directory.
   

3.Added the necessary Gradle configurations to the project-level build.gradle and the app-level build.gradle.

android level build.gradle:
`allprojects {
repositories {
google()
jcenter()
// Add the following line:
maven {url 'https://developer.huawei.com/repo/'}
}
}

buildscript {
repositories {
google()
jcenter()
// Add the following line:
maven {url 'https://developer.huawei.com/repo/'}
}
}
//buildscript > dependencies
buildscript {
dependencies {
// Add the following line:
classpath 'com.huawei.agconnect:agcp:1.9.0.300'
}
}`

app-level build.gradle:
apply plugin: 'com.huawei.agconnect'

4. Included the HMS dependencies agconnect_crash and agconnect_clouddb in my pubspec.yaml:

5. Ran 'flutter pub get' to fetch packages.

But when I try to run the application, the build fails with the following errors:
`PS C:\Users\User\hulatech_teacher_app> flutter run

BUILD FAILED in 49s
Running Gradle task 'assembleDebug'... 50,8s
Exception: Gradle task assembleDebug failed with exit code 1`

HMS dependencies versions provided by the official documentation were out of date, so I checked the pub.dev and updated the versions. I was expecting the app to build successfully and run in debug mode on my emulator/device.

What could be causing these errors, and how can I resolve them?

Hi @UsamaHameed1 sorry for the late response. I couldn't find the solution to that issue. If you found one, please share with me, I`m curious to know what I was missing.

hello @danieldai ,
I saw that you managed to solve the issue that related to the AGC Flutter Plugin. I'm currently facing a similar issue with another plugin, as described in my issue " #16 "
If you have any insights or suggestions on how to resolve this, I would really appreciate your help!
Thanks in advance for your time.
