Hi @tomoyuki28jp thank you for opening the issue! Did you check the known issues on the package information page?

https://pub.dev/packages/package_info_plus#ios

Also, have you tested on a simulator or do you have a real device? Which iOS/macOS version you have tested?

[tomoyuki28jp]

@salihgueler Thanks for your reply.

Did you check the known issues on the package information page?

Yes, I've run my project after cleaning from Xcode.

Which iOS/macOS version you have tested?

I've tested on:

• MacBook Pro (real device) / macOS Big Sur 11.01
• iPhone 8 Simulator / iOS 14.5

For your information I have the same issue on:

• iPhone 7 iOS 13.5
• iPhone 12 iOS 14.5
• iPhone SE 2020 iOS 14.7

It looks like the code for iOS is pulling from CFBundleDisplayName

https://github.com/fluttercommunity/plus_plugins/blob/main/packages/package_info_plus/package_info_plus/ios/Classes/FLTPackageInfoPlusPlugin.m

but my app doesn't have a value for that plist property in Xcode. It only has CFBundleName. I imagine iOS uses CFBundleDisplayName if present, otherwise CFBundleName. Haven't had a chance to check my app's generated Info.plist or test changing the plugin code yet to confirm though.

@tomoyuki28jp As the package currently uses CFBundleDisplayName to get the app name, you probably need to add that in both your iOS and macOS Info.plist files, like the following example.

	<key>CFBundleDisplayName</key>
	<string>Put Your App Name Here</string>

@cjwhitsitt I tried to create a new flutter project, and I found out that CFBundleDisplayName is not added when the project is created. So you would probably have to look into the Info.plist file and add it if necessary. In the meantime, will try to investigate and change CFBundleDisplayName to CFBundleName.

Hope that helps 👍

@mhadaily seems like it is fixed with last merged PR or not yet?

Confirmed this issue has been resolved on my Mac and iPhone. Thanks for your work! @alexbatalov
