Generate a Flutter app with a paywall

paywall is the feature with the paywall of the apps that the SMF CLI generates. It sells the premium access of the app with the plans of the current offer, and has a screen of the subscription for a user with that access. Choose it with -m, here with BLoC for the state of the screens and RevenueCat for the purchases:

dart pub global activate smf_flutter_cli
smf create my_app -m paywall,bloc,revenuecat --no-input

The paywall needs a router, a module that provides the purchases, a module that provides the values in .env and a module that manages state. smf create adds a module when it is the only one that provides what another one requires, and says which module needs it.

The module writes its files into lib/features/paywall/. The route of the screen of the subscription needs premium access, so a button of the app sells by navigating to it:

FilledButton(
  onPressed: () => context.nav.paywall.subscription().push<void>(),
  child: const Text('Go premium'),
)

For a user without premium access, the router opens the paywall over the page first. Once the user has bought a plan, the router closes the paywall and shows the screen of the subscription. A widget reads the access of the user from the cubit that the module puts around the root of the app:

final premium = context.watch<PremiumCubit>().state is PremiumAccess;

Fill in the addresses of your terms of use and of your privacy policy under PAYWALL_TERMS_URL and PAYWALL_PRIVACY_URL in .env. The README of the app tells what the paywall shows and how to change its benefits.
