What Can We Build With Flutter?
One unified codebase powers both the Apple App Store and Google Play Store without compromising UX or frame rates. Choose your app archetype below.
Consumer Digital Commerce & Lifestyle Apps
Fluid mobile storefronts with fast checkout, Apple Pay & Google Pay, push notifications, and high-conversion product catalogues.
Native Hardware Access & Impeller GPU Rendering
Flutter bypasses JavaScript bridges completely. It communicates with device hardware through native platform channels and paints UI directly onto GPU surfaces at 120 frames per second.
// BLoC Event Handler & Hardware Sensor Sync
class CheckoutBloc extends Bloc<CheckoutEvent, CheckoutState> {
on<PayWithBiometrics>((event, emit) async {
final authenticated = await LocalAuthService.authenticate();
if (authenticated) emit(CheckoutSuccess(orderId: event.orderId));
});
}
