[Bug]: IOS - shows duplicated version number when the build number is not specified

[AlexLomm]

Platform

iOS 16.3.1

Plugin

package_info_plus

Version

3.0.3

Flutter SDK

3.7.6

Steps to reproduce

1. Open pubspec.yaml of an app
2. Specify a version without the + suffix. Example: 1.0.1
3. Log somewhere the output of the fromPlatform():

print((await PackageInfo.fromPlatform()).buildNumber); // -> output: 1.0.1

4. Build and run the app

Expected:
An empty string is logged, because the build number is not specified in the pubspec.yaml

Actual
1.0.1 is logged

Code Sample

print((await PackageInfo.fromPlatform()).buildNumber); // -> output: 1.0.1

Logs

This is how iOS returns data, package_info_plus doesn't modify the output from the system.
For buildNumber property plugin uses https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleversion which returns build number if it is specified and version if build number is not specified.

I see. Thanks for the reply, it's a false positive then.

[vbuberen]

I will update docs to mention this fact. Didn't know about it as well till started the research yesterday. Thanks for reporting it.
