paycross_flutter 0.2.0

PayCross payment SDK for Flutter: card payments, 3-D Secure v2, saved cards, Google Pay on Android and Apple Pay on iOS, wrapping the native Android and iOS SDKs.

0.2.0

• Apple Pay on iOS. Pass applePayMerchantId to PayCross.configure and the native SDK renders Apple's own payment button inside the payment sheet. Your app adds no widget and implements no delegate; the result is the same PayCrossResult a card payment returns. The identifier must match the one saved on your PayCross merchant record — the edge compares them and refuses a payment whose two copies disagree. Android accepts and ignores it.
• The button appears only when the session loaded, the session allows wallets, an identifier is configured, and the device has a card it can pay with. It is absent and silent otherwise, including on account-funding sessions, on a simulator, and when the identifier is null, empty or whitespace-only — all three of which mean "not configured".
• Verify Apple Pay on a real device before shipping. applePayMerchantId and googlePayMerchantId are both nullable strings, so on iOS the two are indistinguishable to a compiler or a test suite; this release's iOS forwarding is covered by a device payment rather than by a unit test. Configure Apple Pay with googlePayMerchantId left null when you check it.
• Requires the native iOS SDK at PayCross 0.2.0, up from 0.1.1.

0.1.0

Initial release.

• Card payments through the native PayCross Android and iOS SDKs, presented from a single Dart call: PayCross.presentPayment(sessionToken).
• 3-D Secure v2 challenges and status polling, handled entirely by the native SDKs — no card data passes through Dart.
• Saved cards, when the session's customer has any.
• Google Pay on Android: the native SDK shows the button when the session allows wallets and the device supports it. Pass googlePayMerchantId to PayCross.configure — Google requires it on production requests, though sandbox works without one.
• Sealed PayCrossResult (success / failure / cancelled) with a PayCrossRecovery hint on declines, and PayCrossIntegrationError for integration mistakes. Most of its codes map from stable paycross_* strings raised by the native SDKs; testPrefillInProduction is Dart-side only, raised before anything crosses the platform channel.
• Sandbox and production environments; optional test-card prefill in sandbox.
• Android minSdk 24, iOS 16.0.

Known limitations:

• iOS is card-only: no Google Pay, and Apple Pay is on the roadmap.
• brandColorArgb and googlePayMerchantId apply on Android only and are ignored on iOS.
