[FIXED] Flutter can't delete build folder with flutter clean command

Issue

build file doesn't remove anyway. I tried do that answers but no one work for me

how can I delete this folder?

    Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory.
    - F:\sayed\hadayek_hof\build\flutter_launch\intermediates\merged_res\release\drawable-hdpi-v4
    - F:\sayed\hadayek_hof\build\flutter_launch\intermediates\merged_res\release\drawable-mdpi-v4
    - F:\sayed\hadayek_hof\build\flutter_launch\intermediates\merged_res\release\drawable-v21
    - F:\sayed\hadayek_hof\build\flutter_launch\intermediates\merged_res\release\drawable-xhdpi-v4
    - F:\sayed\hadayek_hof\build\flutter_launch\intermediates\merged_res\release\layout

Failed to remove build. A program may still be using a file in the directory or the directory itself.

Solution

You can use your CMD as an administrator and run the command.

Then, if you are using Android Studio as an IDE, you can process this:

File->Invalidate Caches / Restart

If none of them works, just restart your computer.
