Congratulations on publishing the first version of your Flutter app. You probably landed on this page because you might need to update the app version of your Flutter app. It is very usual that while uploading the next version of your Flutter, we may forget to update the app version and only come to know by a message from the Play Store or app store. So in this tutorial, we’ll learn how you can update app version in Flutter.
Here’s what we’ll cover:
Understanding App Version
Before we change the app version, it is critical to understand what exactly we are going to change and how it affects our app. Basically, the app version can be controlled from the pubspec.yaml file. There you’ll find the following line:
version: 1.0.0+1
The 1.0.0 (before + sign) represents the build name. The 1 (after + sign) represents the build number.
In Android
The 1.0.0 (before + sign) is used as versionName and 1(after + sign) used as versionCode.

In iOS
The 1.0.0 (before + sign) is used as CFBundleShortVersionString and 1(after + sign) used as CFBundleVersion.
