So, I am making a flutter project and I am using,

flutter_background_service: ^5.0.7

and according to it’s pub dev page

Android

• To change notification icon, just add drawable icon with name ic_bg_service_small.

WARNING:

Please make sure your project already use the version of gradle tools below:

• in android/build.gradle classpath 'com.android.tools.build:gradle:7.4.2'
• in android/build.gradle ext.kotlin_version = '1.8.10'
• in android/gradle/wrapper/gradle-wrapper.properties distributionUrl=https://services.gradle.org/distributions/gradle-7.5-all.zip

Now, I need to change the notification icon, so i started doing all the necessary gradle changes.

rest of the changes work fine, but,

when i change the gradle version from classpath 'com.android.tools.build:gradle:7.3.0' to classpath 'com.android.tools.build:gradle:7.4.2'

it starts to throw the following error :

FAILURE: Build failed with an exception.

i have tried updating kotlin-version to 1.9.0, cleaned the project and gradle files. none of it is much helpful

how can i either solve this error, or change the notification icon from flutter-background-service in any other way. it would be greatly appreciated

if you need anymore data, please ping me
