How to Change Version Code and Version Name of Your Flutter App:

We will explain the different methods to change the version code and version name of the app in Flutter. We recommend the first one to use.

Method 1 (Recommended):

Open pubspec.yaml file and get the line below:

version: 1.0.0+1

Here, "1.0.0" is the version name and 1 after "+" is the version code. You can update them like below:

version: 1.1.4+2

Note: Version code is an integer, no decimal is allowed on version code. While, you can use decimals on version name.

Method 2:

Open your_project/android/local.properties file and get the code below:

flutter.versionName=1.0.0
flutter.versionCode=1

You can update them like below:

flutter.versionName=1.1.5 
flutter.versionCode=2 //no deciaml, only integer

Method 3:

Open your_project/android/app/build.gradle file and get the lines below:

defaultConfig {
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

Now, update them with your own version code and version name like below:

defaultConfig {
    versionCode 2
    versionName "1.0.5"
}

In this way, you can update the version code and version name of your app in Flutter.
