Checking Device's Android Version with Flutter

Knowing the Android version of a user's device can be crucial for your Flutter app. This information helps you tailor the app's functionality or display specific features based on compatibility. Flutter offers two main approaches to achieve this:

1. Using the Platform class (Limited Information):

The Platform class provides basic platform information. While it can't directly access the Android version, it helps identify if the device is Android:

Copycopy code to clipboard
1import 'package:flutter/services.dart';
2
3if (Platform.isAndroid) {
4  // Code to handle Android specific logic
5}

This approach is limited as it doesn't provide the actual version number.

2. Leveraging the device_info_plus package (Recommended):

For more detailed information, including the Android version, using the device_info_plus package is recommended. Here's how to do it:

• Add the package to your pubspec.yaml file:

Copycopy code to clipboard
1dependencies:
2  device_info_plus: ^4.2.2

• Import the package and access the device information:

Copycopy code to clipboard
1import 'package:device_info_plus/device_info_plus.dart';
2
3Future<void> getAndroidVersion() async {
4  final DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
5  final androidInfo = await deviceInfo.androidInfo;
6  final version = androidInfo.version.release;
7  print('Android Version: $version');
8}

This code fetches the device information using the DeviceInfoPlugin and extracts the Android version from the release property.

Important Note:

While the androidInfo.version.sdkInt property provides the API level (e.g., 33 for Android 13), parsing this integer into a human-readable version (e.g., 13.0) is not recommended by Flutter documentation due to potential inconsistencies. It's safer to use the release property for the version string. Depending on your use case, you might want to use androidInfo.version.sdkInt though, so it's handy to keep it in mind!
