Flutter application getting error after adding apptics_flutter package to the project.

[khan-raptee]

I am using zoho apptics for flutter my application. I have configured the android plugin and if i run the app it is working fine.To use zoho apptics from my flutter app i should add apptics_flutter package. But when i add the apptics_flutter to my project it starts crashing. Below i have attached the images of how my app works before adding package and after adding the package. please provide solution for this.

@khan-raptee - Thanks for contacting Apptics support!

Updating the JAVA version to 17 and Kotlin to 1.8.0 will resolve this issue.

Do let me know if you need any further assistance from our end.

[khan-raptee]

I have updated kotlin to 1.8.0

I have already JAVA 20 below you can check

java --version
java 20.0.1 2023-04-18
Java(TM) SE Runtime Environment (build 20.0.1+9-29)
Java HotSpot(TM) 64-Bit Server VM (build 20.0.1+9-29, mixed mode, sharing)

My android/build.gradle file >>

buildscript {
    ext.kotlin_version = '1.8.0'
    repositories {
        google()
        mavenCentral()
        maven {
            url uri('libs')
        }
        maven {
            url "https://maven.zohodl.com/"
        }
    }
    dependencies {
        classpath "com.zoho.apptics:apptics-plugin:0.1.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

Still i am getting the same issue

@khan-raptee - I will share a sample project. Also would request you to please remove the logs as it is exposing some identifiers.

[khan-raptee]

Thanks. Please share the project
One more thing is apptics_flutter pub package you've mentioned version 0.1.2

classpath 'com.zoho.apptics:apptics-plugin:0.1.2'

but sometimes in log section we get error to get version 0.2.5

apptics-core-0.2.5

Here is a sample project.. @khan-raptee
All you need to do is include your apptics-config.json file in the app directory.

apptics-core-0.2.5

Also, for the above, it is intended behavior

• Thanks it works for JAVA 17 and kotlin 1.8.0 but, what if i need version for kotlin above 1.8.0 or below 1.8.0 and java below 17 or above 17 , will it works .

• second is some pub packages require JAVA 1.8 , it does not support JAVA 17 which I have defined as to run ZOHO apptics SDK.

• below is such an example i am trying to run my app after adding flutter_contacts pub package to pubspec.yaml.
