Did you know?

If your code checks the current platform with Platform.isIOS, you’ll get a runtime exception when you run on Flutter web. 💥

As an alternative, consider using the Universal Platform package, which works on all platforms and offers a unified syntax. 👍

The UniversalPlatform package and its advantages compared to kIsWeb and the Platform class
The UniversalPlatform package and its advantages compared to kIsWeb and the Platform class

Note that the UniversalPlatform class has two drawbacks:

  • It doesn’t (yet) support tree-shaking of the conditional code (see issue #29 for details)
  • The platform can’t be overridden during testing (see issue #15 for details)

If you don’t want to rely on a 3rd party package to perform platform checks, see my next tip about defaultTargetPlatform and kIsWeb.

Happy coding!
