Any info on how to reproduce this? Were you doing anything particular at the time?

[khusantoy]

I just opened flutter project and ide gave me this error

Any updates on this?

[pq]

If I understand the issue right, there's a kotlin version mismatch and our plugin is requiring a newer version than is bundled w/ 2025.2.3.

My first guess, if this is a new regression, would be that the dependency on the new version is coming from

  id("org.jetbrains.kotlinx.kover") version "0.9.4"

which got bumped from 0.9.0 with a gradle upgrade here:

3ca2955

But I haven't been able to confirm.

/fyi @helin24

Ah and maybe we have to change gradle.properties too?

kotlin.stdlib.default.dependency=true

(Sorry if this is a red herring!)

[helin24]

Gemini tells me this is due to the gradle plugin org.jetbrains.kotlin.jvm being 2.2.0 while the likely kotlin runtime for Android Studio 2025.2 only supports 2.1.0.

However, I seem to also have a kotlin runtime in my own Android Studio 2025.2 that is an earlier version, but I'm not able to reproduce this error.

Potentially, you could check if earlier versions of the plugin don't have this problem - specifically, try v86.0.2 because this one predates the change to the gradle plugin version (70546be). OTOH, if using Flutter plugin v88 works, then this theory doesn't make sense. @khusantoy or @vokarpenko could you try Flutter plugin versions 86.0.2 and 88 and report back?
