I have upgraded flutter to Flutter version 1.2.1. After upgrading when I try to build my application, the following error occurs. Cannot find a solution to this yet. Awaiting ur help.

Finished with error: ProcessException: Process "C:\Users\febin\AndroidStudioProjects\my_flutter_lab\android\gradlew.bat" exited abnormally:

This is the gradle.bat file in my project. In the error message displayed, it is this gradle.bat file which is said to be exited abnormally.

After configuring signing in Gradle I got the following error messages: * Error running Gradle: ProcessException: Process "/Users/.../android/gradlew" exited abnormally: Command: /Users/.../android/gradlew app:properties Finished with error: Please review your Gradle project setup in the android/ folder.

I checked it many times, but could not find out what is wrong.

I then made a new project in Android Studio and copied my old files from lib and assets etc. to the new project. It ran fine, and then I configured signing in Gradle, and the project then ran successfully. So this approach solved the previous Gradle conflicts!!
