Build Issue with Flutter APK Generation using WalletConnect/Web3ModalFlutter

[zubair15121716]

I am new to this so kindly if someone can help a little around this ! I have successfully set up WalletConnect and Web3Modal in my Flutter application according to the documentation provided. The integration works perfectly fine when running the application in debug mode (flutter run), but I encounter an issue when attempting to build the APK using flutter build apk.

The error message I receive during the APK generation process is as follows:

e: C:/Users/DELL/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib/1.8.22/636bf8b320e7627482771bbac9ed7246773c02bd/kotlin-stdlib-1.8.22.jar!/META-INF/kotlin-stdlib-jdk8.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

The binary version of its metadata is 1.8.0, expected version is 1.6.0.

I have attempted to resolve this issue by adjusting the settings in gradle.settings, as follows:

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "7.3.0" apply false
    // from  id "org.jetbrains.kotlin.android" version "1.7.10" apply false to  id "org.jetbrains.kotlin.android" version "1.8.10" apply false
    id "org.jetbrains.kotlin.android" version "1.8.10" apply false
}

I changed the version of org.jetbrains.kotlin.android from 1.7.10 to 1.8.10, but unfortunately, this adjustment did not resolve the issue And Gave :

Could you please provide guidance on how to address this compatibility issue and successfully generate the APK for my Flutter application using WalletConnect/Web3ModalFlutter?

Hello @zubair15121716, this looks like a kotlin-related issue, not WalletConnect's... Did you try this? https://stackoverflow.com/a/67801441/4379258

Thanks for the help the issue has been successfully resolved. I only need to make adjustments to the Kotlin version compatibility and internet permissions for android in the manifest file.
