securepay_api

(dart analyze) (dart pub publish --dry-run) (dart pub publish)

A Flutter package that wraps the SecurePay payment platform API, giving Flutter developers a clean, typed, and idiomatic Dart interface — no need to read the raw docs or wire up HTTP calls yourself.

---

Features

• ✅ Full Dart type safety — every request and response is a named model class
• ✅ Dio-powered HTTP with automatic auth header injection
• ✅ UUID-based X-Request-ID tracing on every request
• ✅ Automatic retry with exponential back-off on transient errors
• ✅ Colour-coded request/response logging (staging only)
• ✅ Staging and production environment configs
• ✅ Meaningful SecurePayException types for easy error handling

---

Getting started

Add to your pubspec.yaml:

dependencies:
  securepay_api: ^0.0.2

Then run:

flutter pub get

---

Usage

Initialise the client

import 'package:securepay_api/securepay_api.dart';

// Staging (development)
final securePay = SecurePayApi(
  apiKey: 'YOUR_API_KEY',
  config: SecurePayConfig.staging(enableLogging: true),
);

// Production
final securePay = SecurePayApi(
  apiKey: 'YOUR_API_KEY',
  config: SecurePayConfig.production(),
);

Key Management — Generate a key

try {
  final response = await securePay.keyManagement.generateKey(
    merchantEmail: jondoe@gmail.com,
  );

  if (response.success) {
    final newKey = response.data["publicKey"];
    print('Generated key: $newKey');
  }
} on SecurePayException catch (e) {
  print('SecurePay error: ${e.message} (HTTP ${e.statusCode})');
}

---

Error handling

All API errors are thrown as SecurePayException:

try {
  await securePay.keyManagement.generateKey(...);
} on SecurePayException catch (e) {
  switch (e.errorCode) {
    case 'UNAUTHORIZED':
      // Handle invalid API key
    case 'BAD_REQUEST':
      // Handle validation errors
    case 'SERVER_ERROR':
      // Handle server-side failures
    case 'NETWORK_ERROR':
      // Handle no internet / timeout
  }
}
