# BuildContext - Platform Extensions

> Instantly check which OS your app is running on (Mobile, Desktop, or specific OS) using simple, direct context getters.

<Warning>
  Since these getters rely on dart:io.Platform, they will throw an error when compiled for the web. Ensure you only use these methods in mobile and desktop applications.
</Warning>
