The build name becomes the first three numbers of the
file and product versions, while the build number becomes
the fourth number of the file and product versions.

Both the build name and number can be overridden in
flutter build windows by specifying --build-name and
--build-number, respectively.

Note:
  Flutter projects created before Flutter 3.3
  need to be updated to set the executable’s version
  information. For more information,
  refer to the version migration guide.

Add app icons

To update the icon of a Flutter Windows
desktop application before packaging use the
following instructions:

In the Flutter project, navigate to
windows\runner\resources.

Replace the app_icon.ico with the desired icon.

If the name of the icon is other than app_icon.ico,
proceed to change the IDI_APP_ICON value in the
windows\runner\Runner.rc file to point to the new path.
