aptoide_iap_android

Change

• BillingResponseCode: added appNotFound = 404 — HTTP 404 propagated by the Aptoide backend when the app or product is not found on Aptoide Connect (wrong public key, app not registered, or product IDs not created in the console)

Change

• Pin Aptoide Android Billing SDK dependency to com.aptoide:android-aptoide-billing:1.3.0 (was 1.+) for reproducible builds

Bug fix

• UnfetchedProduct: the SDK field is statusCode (not responseCode) — fixes "Unresolved reference 'responseCode'" compile error at line 216
• UnfetchedProduct: added productType field (present in the SDK class)
• Kept responseCode as a Dart getter alias pointing to statusCode for API consistency

Bug fixes (Kotlin native layer — verified against SDK 1.3.0 AAR)

• Imports corrected: AptoideBillingClientStateListener and ConsumeResponseListener are in com.aptoide.sdk.billing.listeners, not the root package
• Nested annotations: BillingResponseCode, ProductType and FeatureType are nested @interface annotations inside AptoideBillingClient — they are no longer imported as separate classes (fixes all "Unresolved reference" build errors)
• isFeatureSupported: the SDK method signature is isFeatureSupported(int) not isFeatureSupported(FeatureType) — corrected
• ProductDetailsResponseListener / PurchasesResponseListener: are Kotlin fun interface types — constructor lambda form now used correctly
• SubscriptionOfferDetails: removed non-existent offerId field (causes "Unresolved reference" compile error)
• PricingPhase: removed non-existent billingCycleCount and recurrenceMode fields
• isReady must be called as a method isReady(), not a property

Improvements

• OneTimePurchaseOfferDetails, PricingPhase: exposed Aptoide-specific appcFormattedPrice, appcPriceAmountMicros, fiatFormattedPrice, fiatPriceAmountMicros, fiatPriceCurrencyCode fields
• SubscriptionOfferDetails: added optional trialDetails (TrialDetails with period and periodEndDate)
• Purchase: added isAutoRenewing field (useful for subscription management)
• billingResultToMap: handles nullable debugMessage safely

Bug fixes

• Kotlin imports: corrected package from com.aptoide.billing → com.aptoide.sdk.billing (build would fail otherwise)
• isFeatureSupported: was returning the full BillingResult object instead of the responseCode int (would crash at runtime)
• PurchaseState: corrected constants to match Aptoide SDK values (0=purchased, 1=cancelled) instead of the Google Play Billing Library mapping
• FeatureType: added missing subscriptions enum value
• BillingResponseCode: added featureNotSupported = -2
• Renamed Purchase.isPending → Purchase.isCancelled to reflect actual Aptoide state semantics

Initial release of the Aptoide Android Billing SDK Flutter plugin.
