The official Flutter documentation can be found here.

Flutter failed to delete a directory at "buildflutter_assets"

I’m working on flutter to develop a "map-navigation app". I’m new to it. It showed "some of the dependencies are outdated" so I update the packages and pub files, after that the application is not running on any of the platform (i.e. Desktop, Web, android and ios). It shows the following given error.

Also tried manually deleting the build folder from the project and then executing the app, still facing the same error.

Manually deleting the build folder, applying flutter clean command then running the app still shows the error below:

Flutter failed to delete a directory at "buildflutter_assets". 
The flutter tool cannot access the file or directory.
Please ensure that the SDK and/or project is installed 
in a location that has read/write permissions for the current user.

    The problem is probably because it is not a good idea to have a space in the path to a flutter project ie. ‘HP PC’ would be better named with an underscore instead of the space character.

    The flutter documentation warns you of this here https://docs.flutter.dev/get-started/install/windows

    For anyone who faces this issue in future, as mentioned by @GrahamD this issue is because of space in the path. In this case it’s HP PC that should be HP_PC or HPPC or any valid string. Here are few ways you can troubleshoot this issue.

    • Rename the user account. Examples: mypc, my_pc, MyPc, myPC,
      etc.
    • Change the working directory to the path that doesn’t contain
      space/s. Example: C:UsersPublic etc.
    • Create a new user with a name having no space/s.

    After moving your directory, run flutter clean command and then run your project again. It should work now.

    Note: You may need to install software if you create a new user account.

    This was my error when try to debug the Flutter app on my Android smartphone>:

    Unable to delete directory 'C:UsersJean-PierreDevelopmentFlutteraudio_learnbuildappoutputsapkdebug' 
Failed to delete some children. This might happen because a process 
has files open or has its working directory set in the target directory.

    The problem could only be solved by restarting Windows 10.
