PaystackWebView class

A full-screen widget that opens a WebView to handle Paystack checkout.

This widget loads a small HTML page that invokes the Paystack inline JavaScript SDK. Once the user completes or cancels payment, the result is sent back to Flutter over a JavaScript channel, and this page will Navigator.pop with a result map.

Example

final result = await Navigator.push(
  context,
  MaterialPageRoute(
    builder: (_) => PaystackWebView(
      publicKey: 'pk_test_12345',
      amountSmallestUnit: 150000, // ₦1,500 in kobo
      currency: 'NGN',
      email: 'customer@example.com',
      reference: 'order-123',
    ),
  ),
);

if (result['status'] == 'success') {
  debugPrint('Payment ref: ${result['reference']}');
} else if (result['status'] == 'cancelled') {
  debugPrint('User closed the checkout.');
}
