Did you know?
If you try to access a web-specific API on native platforms, your app will crash. đź’Ą
To prevent this, hide your API behind an “umbrella” file using conditional imports. ✅
Here’s an example showing how to check if the app is using the CanvasKit renderer. 👇
Example code
// is_canvas_kit.dart
export 'unsupported.dart'
if (dart.library.js) 'web.dart'
if (dart.library.io) 'native.dart';
// unsupported.dart
bool isCanvasKitRenderer() {
throw UnsupportedError('Implementation not found on this platform.');
}
// native.dart
bool isCanvasKitRenderer() => false;
// web.dart
import 'dart:js' as js;
bool isCanvasKitRenderer() {
return js.context['flutterCanvasKit'] != null;
}Happy coding!
