New features

• 📱 Initial support for cross-platform RevenueCat Paywalls 🐾 🧱 (RevenueCatUI initial support #852)

Instructions:

• For Android, you need to change your MainActivity to subclass FlutterFragmentActivity instead of FlutterActivity. Also, the min sdk version of the new package is 24. Please make sure your app's android/build.gradle minSdkVersion has that or a higher version.
• Add purchases-ui-flutter in your pubspec.yaml:

dependencies:
  purchases_ui_flutter: 6.15.0-beta.4

Usage:

import 'package:purchases_ui_flutter/purchases_ui_flutter.dart';

await RevenueCatUI.presentPaywallIfNeeded("pro");

Limitations:

• Currently only full screen paywalls are supported
• There is no way to detect paywall events other than using addCustomerInfoUpdateListener

Breaking changes from previous beta:

• Paywalls functionality has been extracted into a new dependency called purchases_ui_flutter. Add purchases_ui_flutter to your pubspec.yaml. Before this release, it was part of the main RevenueCat SDK purchases_flutter.
• A new import is required to use this functionality: import 'package:purchases_ui_flutter/purchases_ui_flutter.dart';
• Usage has changed the class from Purchases.presentPaywall to RevenueCatUI.presentPaywall.
• presentPaywall and presentPaywallIfNeeded now don't return a result. To detect purchases, please use Purchases.getCustomerInfo from the purchases_flutter SDK. A return value will be added in future releases.
