# Stamp the Flutter app build number into pubspec.yaml.
#
# The build number is the total git commit count, so every commit yields a
# monotonically increasing value (e.g. 7.4.4+6145).  The base version
# (X.Y.Z) is taken from the existing pubspec.yaml entry.
#
# This script no longer generates the former C++ "include/version.h" header:
# the native C++ engine and Qt UI were removed, and the Rust engine reports
# its own version via env!("CARGO_PKG_VERSION").  The Flutter "About" page
# shows the app version (pubspec) plus the git revision packaged by
# flutter-init.sh (assets/files/git-revision.txt), none of which depend on a
# generated header.
