pay_with_paystack 1.4.0

A Flutter plugin for Paystack payments via WebView. Supports card, mobile money, bank transfer, USSD, QR, EFT, split payments, custom fields, and a customisable checkout UI.

1.4.0

New Features

• Added progressColor and progressBackgroundColor parameters to now() and internal checkout widgets to allow customisation of the loading spinner, linear progress bar, verification overlay spinner, and action buttons.

Bug Fixes

• Fixed an infinite page loading/refreshing loop in the checkout WebView by caching the WebViewController in the state instead of recreating it on every widget rebuild.

1.3.0

New Features

• Added timeout parameter (Duration, default 30 s) to now() to prevent indefinite hanging on slow networks.
• Added onTimeout callback, fired specifically when the API call times out. Falls back to transactionNotCompleted('timeout') if not set.
• Added enableLogging flag. Set true (or use PaystackConfig(enableLogging: kDebugMode)) to print request/response details via debugPrint. Silent in release builds.
• Added WebView progress bar — a LinearProgressIndicator now appears at the top of the AppBar while the checkout page loads.
• Added PaymentData.requestedAmountInMajorUnit convenience getter, mirroring amountInMajorUnit for the requestedAmount field.
• Added PaystackConfig — app-level config class. Call PayWithPayStack.configure(config) once in main() to set secretKey, currency, callbackUrl, enableLogging, and timeout as global defaults. Individual now() calls can still override any field.
• Added PayWithPayStack.configure(), clearConfig(), and currentConfig — static API for managing global config.
• Added transactionCancelled callback — a VoidCallback? fired when the user explicitly closes the WebView without completing a payment (close button or cancel URL). Previously both cancel and failure routed to transactionNotCompleted.
• secretKey, currency, and callbackUrl are now optional on now() when a global PaystackConfig has been set via configure().
• Added PaystackCartItem.imageUrl — optional product image URL included in cart metadata, visible on the Paystack Dashboard when viewing a transaction.
• Added PaystackCurrency enum — typed, IDE-friendly enum for all supported Paystack currencies: ngn, ghs, zar, usd, kes, xof, egp, rwf. Use PaystackCurrency.ghs.value instead of the raw string 'GHS'.
• Added chargeAuthorization() — silently charges a returning customer using a saved authorization code without showing a WebView. Calls POST /transaction/charge_authorization directly.
• Added PaystackBulkChargeItem — typed model for building bulk charge batches. Use toJson() to serialise items for POST /bulkcharge.

Improvements

• _checkTransactionStatus now handles TimeoutException explicitly with a user-friendly message instead of a silent network error.
• The AppBar close button now correctly fires transactionCancelled instead of _checkTransactionStatus on a user-initiated close.

Exports

• PaystackConfig, PaystackCurrency, and PaystackBulkChargeItem are now exported from pay_with_paystack.dart.

1.2.0

New Features

• Added customer prefill — customerFirstName, customerLastName, and customerPhone pre-fill the Paystack checkout form and appear on the Dashboard automatically.
• Added cartItems: List<PaystackCartItem> — attaches typed line items to transaction metadata (name, amount, quantity). Amounts are in the major currency unit.
• Added customFields: List<PaystackCustomField> — typed, structured fields visible on the Paystack Dashboard for every transaction.
• Added split payment parameters — subaccount, splitCode, transactionCharge, and bearer for routing payments to subaccounts or pre-defined split groups.
• Added invoiceLimit — controls how many times a customer is charged on a subscription plan.
• Added PaystackBearer enum — type-safe account / subaccount fee-bearer selection.
• Added PaystackCartItem model — typed cart line item with name, amount, quantity.
• Added PaystackCustomField model — typed custom field with displayName, variableName, value.
• All new model types are exported from pay_with_paystack.dart.

1.1.0

New Features

• Added PaystackChannel enum for type-safe payment channel selection.
• Added plan parameter to expose subscription plan codes through the public API.
• metadata is now typed as Map<String, dynamic>? instead of dynamic.
• Added AppBar customisation — showAppBar, appBarTitle, appBarColor, appBarTextColor.
• Added loadingWidget parameter for a custom loading widget.
• Added errorWidget builder parameter for a custom error widget with retry callback.
• Retry button on the default error screen retries payment initialisation.
• Added a non-dismissible verification overlay shown while verifying the transaction.
• Added branded loading and error UIs with a pulsing logo animation.
• Added expMonth, expYear, reusable, and signature fields to Authorization.
• Added metadata field and computed fullName getter to Customer.
• Added requestedAmount and orderId fields to PaymentData.
• Added isSuccessful, amountInMajorUnit, and feesInMajorUnit helpers to PaymentData.
• Added toString(), copyWith(), ==, and hashCode to all models.
• Added PaystackException — typed exception with message, statusCode, responseBody.
• Importing pay_with_paystack.dart now re-exports all model types.

Bug Fixes

• Fixed crash: response! force-unwrap after a caught exception now throws a typed PaystackException instead of crashing with Null check operator used on a null value.
• NavigationDecision.prevent is now returned when the cancel or callback URL is detected.

Tests

• Added comprehensive unit test suite for all models and utilities.

1.0.14

• Initial tracked release.
