Flutter - Get app version in iOS using package_info

Question

I need to retrieve the app version from within Dart code in a Flutter project.

I am using package_info and in Android is working OK but in iOS the version property in PackageInfo is null.

My code:

  Future<String> getVersion() async {
    String base = getText(version);
    PackageInfo packageInfo = await PackageInfo.fromPlatform();
    return base.replaceAll("[name]", packageInfo.version);
  }

Any help why is happening this or other way to retrieve the version? In some places of internet it is said that the version must be retrieved from native config files but in my case those files contains a reference to the version defined in pubspec.yaml.

I am using Flutter version 1.0.0

Thanks.

Could you check the CFBundleShortVersionString value in your ios/Runner/Info.plist file ? — diegoveloper, Feb 15 '19 at 16:05
@diegoveloper the value of CFBundleShortVersionString in info.plist is: $(FLUTTER_BUILD_NAME) — svprdga, Feb 15 '19 at 17:04
@diegoveloper I tried with a hardcoded value and it works, but that's precisely what I was trying to avoid, to have the same value in two different places... — svprdga, Feb 18 '19 at 09:38
Exactly @svprdga, im facing the same issue, its always returning 1.0.0, not the version i set in the pybspec.yaml, have u sorted that out ? — Bishoy Hanna, Apr 12 '19 at 14:43
No @BishoyHanna, I just created another var with the version...so I have now the version in pubspec.yaml and in another place... :( — svprdga, Apr 24 '19 at 14:14
I do now change it in pubspec for android and in info plist for ios — Bishoy Hanna, Apr 25 '19 at 15:08

This package_info on iOS requires the Xcode build folder to be rebuilt after changes to the version string in pubspec.yaml. Clean the Xcode build folder with: XCode Menu -> Product -> (Holding Option Key) Clean build folder. see this

Add below two line in your plist file inside dict:

<key>CFBundleDisplayName</key>
<string>Package Info Example</string>
