How do you detect the host platform from Dart code

Question

For UI that should differ slightly on iOS and Android, i.e. on different platforms, there must be a way to detect which one the app is running on, but I couldn't find it in the docs. What is it?

Answer 1

You can detect the host platform from Dart code using the Platform class provided by the dart:io library. The Platform class provides static properties that you can use to determine the current platform your Dart code is running on.

Here is an example of how to use the Platform class to detect the current platform:

import 'dart:io';

void main() {
  if (Platform.isIOS) {
    print('Running on iOS');
  } else if (Platform.isAndroid) {
    print('Running on Android');
  } else {
    print('Running on some other platform');
  }
}

In this example, the isIOS and isAndroid properties of the Platform class are used to determine whether the code is running on iOS or Android. The isIOS property will be true if the code is running on iOS, and false otherwise. Similarly, the isAndroid property will be true if the code is running on Android, and false otherwise.

Note that the dart:io library is not available for use in web applications, so if you are building a web application, you will need to use a different approach to determine the current platform.
