1.3.0

• Refactor: Adapter pattern for native layers

  • Android: Extracted per-channel adapters (MPayAdapter, AliPayAdapter, WeChatPayAdapter, HongKongWalletAdapter) behind a common PayChannelAdapter interface; MpayPlugin is now a thin dispatcher that routes method-channel calls through PayChannelAdapterRegistry.
  • Android: Shared WeChat IWXAPI state moved into WeChatSession; payment result text mapping centralized in PayResultMapper.
  • iOS: Same adapter split (MPayAdapter, AliPayAdapter, WeChatPayAdapter, HongKongWalletAdapter) with a one-shot PendingResult delivery guard; WeChat registration state (isRunning / cachedOpenUrlRequest) is now owned by WeChatPayAdapter.
  • Removed dead code: lib/response/wechat_response.dart, lib/response/cancelable.dart, and the unused Android PermissionHandler.
  • The Dart public API and the method-channel protocol are unchanged.

• New: Native QR-code generation for scan-to-pay.

  • New generateQrCode method-channel API (code + optional size) returning PNG bytes; rendered natively — ZXing core on Android, CoreImage CIQRCodeGenerator on iOS. No new Dart or plugin dependencies.
  • New QrPayView widget renders the QR from server-issued qr_code / code_url strings (Alipay precreate / WeChat Native).
  • Black-on-white, ErrorCorrectionLevel M, size clamped to 64..1024.
  • Payment-result confirmation (server polling / async notify) remains the merchant server's responsibility.

1.2.1

• Bug fixes:

  • Android: Fixed NullPointerException caused by mActivity!! force-unwrap when the plugin is invoked before an Activity attaches.
  • Android: Fixed all four ActivityAware lifecycle callbacks (onDetachedFromActivity, onDetachedFromActivityForConfigChanges, onReattachedToActivityForConfigChanges). Previously empty, they now properly update and null-out the Activity reference, preventing stale references and memory leaks across screen rotations.
  • Android: registerApp now uses Application Context instead of Activity Context to avoid a WeChat IWXAPI memory leak.
  • Android: Added a resultSent guard in MPayHandler to prevent MethodChannel.Result from being called more than once when multiple SDK callbacks fire.
  • Android: payWithHongKongWallet now returns a Map consistent with all other payment methods (was incorrectly returning a raw Boolean, crashing ResultModel.fromJson).
  • Android: Fixed the errCode.toString() isEmpty check in WXAPIEventHandler that was always true (dead else-branch removed).
  • Android: Fixed timestamp argument parsing in WeChat Pay to handle both Int and Long from the Flutter method channel codec.
  • Android: PermissionHandler updated from the deprecated android.app.Fragment API to AndroidX ActivityCompat, and now skips the no-op WRITE_EXTERNAL_STORAGE request on Android 13+.
  • iOS: Replaced all Objective-C implementation files with Swift. Fixed a critical bug where _result was declared as a file-scoped global variable in MPayHandler.m, causing concurrent payment callbacks to corrupt each other's result pointers.
  • iOS: Added a resultSent guard in MPayHandler (mirrors Android fix).
  • iOS: onGetResult now safely handles nil fields from the Alipay SDK instead of crashing with NSInvalidArgumentException: attempt to insert nil object.
  • iOS: WeChat payment pendingResult is cleared immediately after use to prevent double-delivery.
  • Dart: invokeMethod return values are now null-safe ((response as Map?) ?? {}), preventing a crash in ResultModel.fromJson when the platform returns null.
  • Dart: Fixed ResultModel.toString() which was missing colons after result, memo, and type labels.
  • Dart: Removed stale print() debug statement from aliPay.

• iOS rewrite (Objective-C → Swift 5):

  • MpayPlugin, MPayHandler, WXAPIEventHandler, WeChatPayDelegateHeader converted to Swift. The three WeChatSDK bridge headers (WXApi.h, WXApiObject.h, WechatAuthSDK.h) are retained as ObjC headers for the static library interface.
  • Podspec updated: swift_version = '5.0', minimum iOS raised to 12.0.

1.2.0

• Added Hong Kong WeChat Wallet payment via HongKongWallet(prepayId: token).
• PayType is now a sealed class; use Payment(...) for standard WeChat Pay or HongKongWallet(...) for the HK Wallet flow.

1.1.0

• Added direct Alipay payment (aliPay) bypassing the MPay channel.
• Added direct WeChat Pay (wechatPay) with registerApi pre-registration.
• iOS Universal Link support for WeChat registration.

1.0.0

• Initial release.
• MPay unified channel supporting MPay, Alipay, and WeChat Pay.
• init for configuring Alipay sandbox/online and MPay SIT/UAT/Production environments.
