How to use defaultTargetPlatform and kIsWeb

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. 💥

To prevent this, check for kIsWeb beforehand and use it together with defaultTargetPlatform, which doesn't import dart:io. 👍

Why are kIsWeb and defaultTargetPlatform both needed?

According to the docs:

• kIsWeb is a boolean which is true if the application is running on the web
• defaultTargetPlatform returns which platform the browser is running on
