Flutter Stripe payment integration

Flutter Stripe Payment Integration (Android + iOS)

by


Introduction

Flutter Stripe payment integration if you’re building a Flutter app and want to accept payments securely, Stripe is one of the most powerful and developer-friendly payment gateways available today.

In this tutorial on Flutter Stripe payment integration, we’ll set up Stripe payments in a Flutter app for both Android and iOS — using the official Flutter Stripe SDK.

What We Are Building

We will create a Flutter app that:

  • Accepts payments using Stripe
  • Works on Android & iOS
  • Uses Stripe Payment Sheet
  • Shows secure payment UI
  • Handles success & failure flow


Required Flutter Packages for Stripe Payment Integration

We use the official Stripe Flutter package:

flutter_stripe

Stripe API Key Setup for Payment Integration

Before writing code, you must:

Create Stripe account

Get Publishable Key

Payment Intent client secret

Enable test mode

In the app initialization, we configure Stripe with the publishable key.

Stripe.publishableKey = "YOUR_PUBLISHABLE_KEY";



Getting Started with Payment Gateway

👉 Where to get this key + how to configure — shown step-by-step in the video.

Basic Flutter App Structure

UI is very simple — just a button that triggers payment.

ElevatedButton(
  onPressed: makePayment,
  child: Text("Make Payment"),
)


Step-by-Step Integration with Stripe

But the real logic is inside the payment method flow, which includes PaymentSheet initialization and presentation.

I explain each parameter and why it is needed in the tutorial video.


Flutter payment integration example

Stripe Payment Sheet is the major step in mobile app for Flutter payment gateway

requires:

  • Payment Intent client secret
  • Merchant name
  • Theme mode
  • Optional styling

Conceptually it looks like this:

Stripe.instance.initPaymentSheet(
  paymentSheetParameters: SetupPaymentSheetParameters(
    paymentIntentClientSecret: "...",
    merchantDisplayName: "...",
  ),
);

Presenting Stripe Payment Sheet

After initialization, we present the payment UI:

await Stripe.instance.presentPaymentSheet();

Testing Flutter Stripe Integration: Sandbox vs Production

In this Flutter stripe tutorial, I’ll explain the flow and key setup steps — but the full working code and live payment demo are shown in the video tutorial (linked below).

Production Tips and Best Practices

Before going live:

  • Never expose secret keys in app
  • Use backend to create payment intent
  • Switch from test to live mode
  • Test with Stripe test cards
  • Verify webhook flow (explained in video)
