ntt_atom_flutter 2.0.0

A Flutter SDK for integrating NTT Atom Pay, enabling seamless payment processing with secure and efficient transactions.

2.0.0

• Breaking: AtomSDK is now a fully static class; call AtomSDK.checkOut(...) directly instead of AtomSDK().checkOut(...)
• Breaking: Renamed AtomPaymentMode to AtomEnv and AtomReturnUrlMode to AtomCallbackMode
• Breaking: Replaced the flutter_inappwebview WebView backend with webview_flutter; replaced http/crypto with dio/cryptography for networking and hashing
• Fixed AtomCallbackMode.forwardEncrypted and forwardUnencrypted being swapped: forwardEncrypted now forwards only the raw encData=<value> payload, and forwardUnencrypted now forwards the decrypted JSON payload, matching their names
• Added UPI deep-link support for Google Pay, PhonePe, and Paytm, with a snackbar fallback when the target app isn't installed
• Added onUserExitRequest callback to checkOut to intercept and optionally block the user leaving the payment screen (e.g. system back gesture)
• Added preProcessorDialogBuilder to checkOut for supplying a custom dialog shown while the transaction token is being requested
• Fixed SDK not closing with AtomTransactionStatus.failed when a JavaScript error occurs in the checkout WebView
• Fixed unhandled failure when the Atom checkout CDN script fails to load
• Reorganized package internals (models/, helpers/, routes/, ui/, constants/) and added full dartdoc coverage for all public API members
• Updated dependencies: freezed 3.2.5, json_serializable 6.14.0, build_runner 2.15.1, flutter_lints 6.0.0; bumped minimum Dart SDK to ^3.12.2

1.0.7+1

• Updated Readme

1.0.7

• Added AtomReturnUrlConfig model with three forwarding modes: sendToServer, forwardEncrypted, and forwardUnencrypted
• Replaced returnUrl string field in AtomPaymentOptions with nullable returnUrlConfig: AtomReturnUrlConfig?; passing null (default) preserves existing behavior
• forwardEncrypted: SDK captures response at default URL, POSTs extracted encrypted payload as plain text to provided URL, then decrypts to determine transaction status
• forwardUnencrypted: SDK captures response at default URL, decrypts it, POSTs JSON to provided URL, then determines transaction status
• Empty returnUrl in config falls back to default SDK behavior
• Renamed AtomConstants.defaultUrl to AtomConstants.defaultReturnUrl for clarity; added as @Default on AtomReturnUrlConfig.returnUrl
• Added iOS LSApplicationQueriesSchemes and Android <queries> setup instructions to README
• Updated example app with amount input, return URL input, and mode dropdown
