@liangchuying It may be occuring due to incompatibility. Did you add any plugin recently after which it started occuring ? I accidentally had this error after I added interactive_media_ads plugin. After removing it, the error didn't occur, so check if any of the plugin's kotlin version or gradle version compatibility is triggering the error or not.

Another way could be caching. See https://github.com/flutter/flutter/issues/146038#issuecomment-2035504109

[liangchuying]

I have confirmed that I have not installed any new plugins recently, but I have updated Android Studio and Flutter SDK. I am trying to update Gradle and Kotlin.

[Gonzalo-Bruna]

I have the same issue, but in my case, the issue happens after I installed the upgrader package. I tried upgrading Kotlin but it didn't fix the issue. If that's the case, should I open an issue on the package repository?

[liangchuying]

My problem was that the version of url_launcher_android 6.3.13 conflicted with my project.

[darshankawar]

@liangchuying

url_launcher_android 6.3.13 conflicted with my project.

Are you explicitly using this plugin in your project ? It is endorsed, so just using url_launcher should suffice. Does the error occur after you added this plugin and removing it also doesn't cause the error anymore ?

Is there a way to replicate this consistently with just this plugin and barebone code and conflicting package ?

having same issue possible duplicate to this minSdk set to 24

We had the same issue. We solved it by setting minifyEnabled to true in our android/app/build.gradle:

android {
   buildTypes {
        release {
            minifyEnabled true
        }
        profile {
            minifyEnabled true
        }
        debug {
            minifyEnabled true
        }
   }
}

We had the same issue. We solved it by setting minifyEnabled to true in our android/app/build.gradle:

android {
   buildTypes {
        release {
            minifyEnabled true
        }
        profile {
            minifyEnabled true
        }
        debug {
            minifyEnabled true
        }
   }
}

This helps, but i think we need to know what was causing this problem, in my case from last build i did not add any dependencies.

[liangchuying]

Try to go back to the available project branch and try it

[darshankawar]

@liangchuying Is this resolved at your end and can it be closed ?

[liangchuying]

yes, Thank you. Excuse me

[darshankawar]

Closing as resolved based on above comment.
