Your project requires a newer version of the Kotlin Gradle plugin.

when I upgrade to version 2.0.0, the project fails to compile and prompts to upgrade to the latest Gradle.
Is it possible that flutter_callkit_incoming is using syntax or features that are only supported in the latest Gradle version?

[hiennguyen92]

you can try add in android/build.gradle

buildscript {
ext.kotlin_version = '1.8.0'
...
}

change version to 1.8.0

[yoer]

after change version to 1.8.0

I think you need to upgrade Gradle version

This problem has been blocking my project for a while.
Can you please tell me the specific reasons that caused it?
It occurs when upgrading to version 2.0.
Additionally, my project does not use sqlite.

you can set Android Studio build with java8. Setting>Build Tool>Gradle> set java8 instead of 11
