PhonePe Checkout (Flutter)

A minimal Flutter helper demo for taking payments with PhonePe using a WebView/deep-link style flow (phone_pe package).
The example shows how to start a checkout, configure sandbox vs. production, and handle the resulting status.

This package/example is not an official PhonePe SDK. Use sandbox credentials for development and never ship your secret keys in the client. For production, do signing/verification on your backend and use PhonePe webhooks.

Features

Start a PhonePe checkout from Flutter
Sandbox and production configuration examples
Return to app using a deep link (e.g., myapp://payment-return)
Simple status handling with snackbars and UI state

Getting started

Installation

Add the dependency in your app pubspec.yaml:

dependencies:
  phonepe_flutter: ^1.1.0

Then run:

flutter pub get

If you're developing the phone_pe package itself, the example app depends on it via a local path: ../ in example/pubspec.yaml (see below).

Deep links

Android: add an intent filter in the main activity for your scheme/host.
iOS: configure URL Types in Info.plist with the same scheme.

In this demo flow, the in-app WebView intercepts navigation to the returnDeepLink and the example handles the result in Dart.

Example usage

final result = await PhonePeCheckout.startPayment(
  context: context,
  config: sandboxConfig,
  amountPaise: 10000, // ₹100.00 (paise)
  returnDeepLink: 'myapp://payment-return',
);

// result.status: "SUCCESS" | "PENDING" | "FAILED" | provider-specific

See the full example in example/lib/main.dart.

Security notes

Do not embed production secrets in the app. Sign/verify requests on your server.
For live traffic, confirm transactions via PhonePe webhooks / server-side verification.
Keep enableLogs off in release builds.
