versionName property
The marketing version this build was uploaded under, or null for a run that named none.
Nullable here and not on PlayUploadResult, which is the stores
again. play upload resolves a version name from the pubspec when no
flag gives one, because Play needs something to call the release in the
console; an App Store upload carrying no artifact and no --metadata
version has nothing to resolve one for, and inventing one would put a
number on this line that no Apple record carries.
Implementation
final String? versionName;
