How to set build and version number of Flutter app

Question

How do you set the version name and version code of a Flutter app without having to go into the Android and iOS settings?

In my pubspec.yaml I have

version: 2.0.0

but I don't see a place for the build number.

Solution 1

Setting the version and build number

You can update both the version name and the version code number in the same place in pubspec.yaml. Just separate them with a + sign. For example:

version: 2.0.0+8

This means

• The version name is 2.0.0
• The version code is 8

This is described in the documentation of a new project (but you might have deleted that if you are working on an old project):

The following defines the version and build number for your application. A version number is three numbers separated by dots, like 1.2.43 followed by an optional build number separated by a +. Both the version and the builder number may be overridden in flutter build by specifying --build-name and --build-number, respectively. Read more about versioning at semver.org.

version: 1.0.0+1

Re-enabling auto versioning

If your Flutter versioning is not automatically updating anymore, see this answer for how to fix it.

Thanks to user abion47 for finding and condensing the following answer from the article Versioning with Flutter.

Re-enabling auto versioning

By default a Flutter project is set up to automatically update the Android and iOS settings based on the version setting in pubspec.yaml when you build the project. If, however, you have since overridden those settings, you can re-enable that behavior by doing the following:

iOS

Open the ios/Runner/Info.plist file. Set the value for CFBundleVersion to $(FLUTTER_BUILD_NUMBER) and set the value for CFBundleShortVersionString to $(FLUTTER_BUILD_NAME). The XML for the file should look something like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  ...
  <key>CFBundleVersion</key>
  <string>$(FLUTTER_BUILD_NUMBER)</string>
  <key>CFBundleShortVersionString</key>
  <string>$(FLUTTER_BUILD_NAME)</string>
  ...
</dict>
...

Android

Open the android/app/build.gradle file. Ensure you are properly loading the Flutter properties at the top of the file:

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    throw new GradleException("versionCode not found. Define flutter.versionCode in the local.properties file.")
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    throw new GradleException("versionName not found. Define flutter.versionName in the local.properties file.")
}

Then set the android.defaultConfig section so that versionName is flutterVersionName and versionCode is flutterVersionCode.toInteger():

android {
  ...
  defaultConfig {
    ...
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
  }
}

Solution 3

In Android, build-name is used as versionName while build-number used as versionCode. Read more about Android versioning at https://developer.android.com/studio/publish/versioning In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion. Read more about iOS versioning at https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

This above information you can get in pubsec.yaml

You will find versionCode or buildnumber (for android) in your android/app/build.gradle.

defaultConfig {
        applicationId "com.fabio.resturanto"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true

    }

You have flutterVersionCode and flutterVersionName in your local.properties file. This is specific to Android build

Both iOS / Android version can be set from pubspec.ymal

version: 1.2.0+1

Here 1.2.0 is Version Name and +1 is Version code. changes here (pubspec.ymal) will reflect for both Android and iOS version name and version code.

Solution 4

What worked for me (Android) :

• Update pubspec.yaml inside flutter project file for versionname and versioncode.
• Run flutter pub get on terminal.
• Run your project in a device.
• Open android module in Andriod Studio and check local.properties for updated flutter.versionName flutter.versionCode file in gradle folder.

Solution 5

For me my version was

version: 1.0.0+1

and i changed it to

version: 1.2.0+2

then in terminal

flutter build appbundle --build-name=1.2.0+2 --build-number=2
