Solution

The key message is that the :app:compileDebugKotlin task didn't complete successfully. This task is responsible for compiling Kotlin code in your Android app (when using Kotlin in a Flutter or Android project that relies on Gradle for builds).

Review the Kotlin code in your app's source files. Look for any syntax errors, incorrect type declarations, or other common coding mistakes. Even a small error like a missing parenthesis or a misspelled keyword can cause the compilation to fail. Pay special attention to recently added or modified Kotlin files as they are more likely to be the source of the problem.

Make sure all Kotlin classes and functions are properly defined and that there are no unresolved references to other classes, variables, or functions.
