How to get build and version number of Flutter app

How to Get Build and Version Number of a Flutter App

📱 Are you developing an awesome Flutter app? 🚀 Do you want to display the build and version number to your users? 🏷️ No worries, we got you covered! In this guide, we'll walk you through the steps to get the build and version number of your Flutter app.

The Challenge

⚠️ Imagine you're developing an app in beta mode and want to show your users the version they are currently on. For example, "v1.0b10 - iOS". You've already tried using the code Text("Build: V1.0b10 - " + (Platform.isIOS ? "iOS" : "Android")), but you still need to fetch the actual build version and number dynamically.

The Solution

✅ To solve this challenge, we'll use the package called package_info. This package provides access to various information about the application, including the version number and build number.

💡 Here are the easy steps to get the build and version number of your Flutter app:

1. Add the package_info dependency to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  package_info: ^2.0.3

1. Run flutter pub get to fetch the dependency.

2. Import the package_info package in your Dart file:

import 'package:package_info/package_info.dart';

1. Get the build and version numbers using the PackageInfo class:

PackageInfo packageInfo = await PackageInfo.fromPlatform();
String version = packageInfo.version;
String buildNumber = packageInfo.buildNumber;

1. Use the obtained version and buildNumber variables wherever you want to display the information in your app:

Text("Build: ${version}b${buildNumber} - ${Platform.isIOS ? "iOS" : "Android"}")
// Example output: "Build: v1.0b10 - iOS"

That's it! 🎉 You will now be able to display the actual build and version number dynamically in your Flutter app.
