Fonts
If you are using google_fonts package to load custom fonts in your app, you need to pre-load the fonts in Widgetbook, to avoid visual font swaps.
widgetbook/lib/main.dart
Future<void> main() async {
// TODO: replace `lato` with your desired font
WidgetsFlutterBinding.ensureInitialized();
await GoogleFonts.pendingFonts([GoogleFonts.lato()]);
runApp(const WidgetbookApp());
}
