Flutter not using build number from pubspec.yaml

Question

When I run flutter build run I expect the version and build number to user my version in pubspec.yaml 1.1.5+10

However the 10 is always reverting to 1. This is set correctly in info.plist

  <key>CFBundleVersion</key>
  <string>$(FLUTTER_BUILD_NUMBER)</string>
  <key>CFBundleShortVersionString</key>
  <string>$(FLUTTER_BUILD_NAME)</string>

But when I open xcode v12.2 it's changing $(FLUTTER_BUILD_NUMBER) back to

<key>CFBundleVersion</key>
<string>$(CURRENT_PROJECT_VERSION)</string>

Somehow xcode itself is reverting these changes in info.plist.

Answer 1

It's a problem in the ios/Runner.xcodeproj/project.pbxproj file
I solved with this update my version and build number

change this:

CURRENT_PROJECT_VERSION = your buildnumber
MARKETING_VERSION = your version

to:

CURRENT_PROJECT_VERSION = "$(FLUTTER_BUILD_NUMBER)";
MARKETING_VERSION = "$(FLUTTER_BUILD_NAME)";

worth noting that CURRENT_PROJECT_VERSION and MARKETING_VERSION exist 3 times in the file, not just once – Heiser

I have encountered similar problem multiple times. What I did was set Generated configuration for all profiles [PROFILE] (Debug, Release, Profile).

Go to XCode -> Runner -> Project (Runner) -> Info.

On Target level all Runners were using Pods-Runner.[PROFILE]. On Project level there was no configuration used, so I selected Generated for all.

I don't know what are the actual implications of this change, but build version and name are picked up from Generated.xcconfig file now.

The information in Xcode will not update just because you update and save pubspc.yaml. You must rebuild for iOS in order for the changes to be reflected in Xcode.

Rebuild means running “flutter build iOS” ? Need more detailed steps. – Boyfriend

this should be the right answer. Yes its "flutter build ios" – Canty

Answer 4

This is because Flutter build/run CLI overwrites iOS/Android build version from pubspec.yaml.

In my case, I use manually build(gym command of fastlane) and build version was same as before.

Use flutter build for build or you have to manually overwrite the version.

Running flutter build ios is required. Otherwise you have to: 1. Manually edit Info-Debug.plist and Info-Release.plist and update those keys/rows (FLUTTER_BUILD_NAME & FLUTTER_BUILD_NUMBER respectively). 2. Then manually change version and build number from your Target -> General tab -> Identity section -> "Version" and "Build" – Sharpnosed

My solution was to go to the file located at this address:

./ios/runner.xcodeproj/project.pbxproj

Once opened the file had the following value defined:

FLUTTER_BUILD_NUMBER = 5

I replaced it with this:

FLUTTER_BUILD_NUMBER = "$(FLUTTER_BUILD_NUMBER)";

I got the version number working in the app using flavors.
