onepref 0.0.25

This package is a well-structured wrapper around Flutter's in_app_purchase API that centralizes in-app purchase (IAP) logic for both Android (Google Play) and iOS (App Store).

Bug Fixes

• [Fixed] OnePref — Added _ensureInitialized() guard: methods now throw a clear StateError when init() was not called, instead of silently no-oping.
• [Fixed] OnePref — All setter methods now correctly return Future<bool> instead of untyped Future.
• [Fixed] OnePref — getBool, getInt, getDouble return types changed from nullable (bool?, int?, double?) to non-nullable since they already provide a fallback default.
• [Fixed] Benefit — Widget fields made final; removed unnecessary // ignore: must_be_immutable suppression.
• [Fixed] Benefit — Critical bug: the icon constructor parameter was being ignored. Icons.check was hardcoded in the build method. Now correctly uses the provided icon.
• [Fixed] OnClickAnimation — Replaced TickerProviderStateMixin with SingleTickerProviderStateMixin (only one controller is used).
• [Fixed] OnClickAnimation — onTap parameter type changed from untyped Function to VoidCallback.
• [Fixed] InAppEngine.upgradeOrDowngradeSubscription — Replaced an unsafe as cast that would crash at runtime with a safe is type-check.
• [Fixed] InAppEngine.purchaseListener — Loop now processes all purchases in the list instead of returning after the first item. This fixes batch restore events being silently discarded. Return type changed to List<PurchaseResult>.
• [Fixed] pubspec.yaml — platforms: key moved inside the flutter: section where it belongs (was incorrectly at top level).
• [Fixed] README.md — Removed references to restorePurchases() and initPurchaseStream() which did not exist. Updated all examples to match current APIs.

New Features

• [New] OnePref.setStringList(String key, List<String> value) — Saves a list of strings.
• [New] OnePref.getStringList(String key) — Reads a list of strings.
• [New] OnePref.containsKey(String key) — Checks if a key exists.
• [New] InAppEngine.restorePurchases() — Wraps InAppPurchase.restorePurchases(). Results arrive via the existing purchaseStream.
• [New] InAppEngine.handlePurchase now returns Future<bool> indicating whether the purchase flow was successfully initiated.
