If you encounter the "your project requires a newer version of the kotlin gradle plugin" error while running your Flutter app, it means that your project requires a newer version of the Kotlin Gradle plugin than what you currently have configured in your build.gradle file. To resolve this error, you can follow these steps:
Open your Flutter project in a text editor or an integrated development environment (IDE).
Locate the build.gradle file in the android directory of your Flutter project.
Inside the buildscript block of the build.gradle file, find the following line:
ext.kotlin_version = '<your kotlin version>'
Replace <your kotlin version> with a newer version of Kotlin. You can find the latest version of Kotlin at the official Kotlin website or in the Kotlin Gradle plugin documentation.
Now the latest kotlin version is :
ext.kotlin_version = '1.7.10'
Update the Kotlin Gradle plugin version by locating the following line in the buildscript block:
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:<your kotlin version>"
Replace <your kotlin version> with the same Kotlin version you specified in the previous step.
Save the build.gradle file and close it.
Now, go to your terminal or command prompt and navigate to your Flutter project's root directory.
Run the following command to clean the project:
flutter clean
After the clean command finishes, run your Flutter app again:
flutter run
The updated Kotlin Gradle plugin version should now be used, and the error should be resolved.
By following these steps and updating the Kotlin version in your build.gradle file, you should be able to resolve the "your project requires a newer version of the kotlin gradle plugin" error and run your Flutter app successfully.
