Flutter — installation

The Flutter SDK ships as pdirect_pay on pub.dev.

Requirements

Dart SDK	^3.8.1
Flutter	>=3.3.0
Android	minSdkVersion 21
iOS	12.0+

Web, macOS, Linux, and Windows are not supported. The package’s pubspec.yaml only declares Android and iOS plugin classes.

Add the dependency

flutter pub add pdirect_pay

Or add manually to pubspec.yaml:

dependencies:
  pdirect_pay: ^3.0.0

Pin to a major version (^3.0.0) and let minors and patches roll forward. See Versioning for the policy.

Verify the install

Run:

flutter pub get
flutter pub deps | grep pdirect_pay

You should see pdirect_pay 3.0.0 (or newer minor) plus its transitive deps (dio, rxdart, flutter_secure_storage, device_info_plus, webview_flutter, pay, crypto, uuid, intl, pdf, printing, flutter_svg).

Platform setup

Android

The plugin auto-registers via Flutter’s plugin system. The native class is com.mms.pdirect_pay.PdirectPayPlugin.

Required permissions in android/app/src/main/AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <uses-permission android:name="android.permission.INTERNET" />
  <!-- ... your application tag ... -->
</manifest>

Google Pay (optional — only if you’ll surface the payment_method: google_pay flow):

<application>
  <meta-data
    android:name="com.google.android.gms.wallet.api.enabled"
    android:value="true" />
</application>

iOS

The plugin auto-registers via CocoaPods. Run:

cd ios
pod install

Apple Pay (optional — only if you’ll surface payment_method: apple_pay): in Xcode, enable the Apple Pay capability on your target. Add your merchant ID under Signing & Capabilities → Apple Pay.

No Info.plist keys are required for the gateway flow itself. The SDK uses the standard URLSession for networking; no special ATS exceptions are needed (the gateway only serves over HTTPS).

Verify it imports

import 'package:flutter/material.dart';
import 'package:pdirect_pay/pdirect_pay.dart';

void main() {
  PdirectPay.init(const PdirectPayConfig(
    environment: PdirectPayEnvironment.sandbox,
    defaultLocale: 'en',
  ));
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: Scaffold(
      body: Center(child: Text('Pdirect SDK ready: ${PdirectPay.isInitialized}')),
    ));
  }
}

flutter run should print Pdirect SDK ready: true once the app launches.

Next steps

1. Configure the SDK for your environment.
2. Read the quickstart to wire up an end-to-end checkout.
3. Skim the API reference for everything beyond the drop-in widget.
4. Read platform notes for any Android- or iOS-specific gotchas.
