'ERROR:: Unknown Directory structure, both java & kotlin files not found

As I was trying to change my package name using a package (change_app_package_name). I bumped into this error:-

Old Package Name: com.milanzi.shamba_huru
Updating build.gradle File
Updating Main Manifest file
Updating Debug Manifest file
Updating Profile Manifest file

ERROR:: Unknown Directory structure, both java & kotlin files not found.

Seems the package cannot find either java or kotlin files within the directory.

I have solved by changing the directory name where the MainActivity.kt is placed

For example

  • First your package name is com.example.app_name

  • Then you need to change into com.milanzi.shamba_huru (use your own package name)

  • Run

    flutter pub run change_app_package_name:main com.milanzi.shamba_huru

So if the error appears, you just need to create a new folder by name of your package

  • Before your path was /android/app/src/main/kotlin/com/example/app_name/MainActivity.kt
  • Change into /android/app/src/main/kotlin/com/milanzi/shamba_huru/MainActivity.kt
  • Now try run against flutter pub run change_app_package_name:main com.milanzi.shamba_huru

NB: If you didn't change the folder name, you can't run it on android. But you can run on IOS.
