Usage #

First initilize the SDK

stripeTerminal = StripeTerminal(
fetchToken: () async {
// Call your backend to get the connection token and return to this function
// Example token can be.
const token = "pst_test_XXXXXXXXXX....";

return token;
},
);

Example backend code to get the connection token written on node.js:

import Stripe from "stripe";
import express from "express"

const stripe = new Stripe("sk_test_XXXXXXXXXXXXXXXXXX", {
apiVersion: "2020-08-27"
})

const app = express();

app.get("/connectionToken", async (req, res) => {
const token = await stripe.terminal.connectionTokens.create();
res.send({
success: true,
data: token.secret
});
});

app.post("/createPaymentIntent", async (req, res) => {
const pi = await stripe.paymentIntents.create({
amount: 1000,
currency: "USD",
capture_method: "manual",
payment_method_types: ["card_present"]
})

res.send({
success: true,
paymentIntent: pi
})
})

app.listen(8000, () => {
console.log("Server started")
});

Discover the devices nearby and show it to the user

stripeTerminal
.discoverReaders(simulated: true)
.listen((List<StripeReader> readers) {
setState(() {
this.readers = readers;
});
});
copied to clipboard

Connect to a bluetooth reader

bool connected = await stripeTerminal.connectBluetoothReader(readers[0].serialNumber);
if(connected) {
print("Connected to a device");
}
copied to clipboard

Scan a card from the reader

stripeTerminal
.readReusableCardDetail()
.then((StripePaymentMethod paymentMethod) {
print("A card was read, the last four digit is ${paymentMethod.card?.last4}");
});
copied to clipboard

Scan payment method from the reader using tap, swipe, insert method

// Get this from your backend by creating a new payment intent

Future<String> createPaymentIntent() async {
Response invoice = await _dio.post("/createPaymentIntent");
return invoice.data["paymentIntent"]["client_secret"];
}

String payment_intent_client_secret = await createPaymentIntent();

stripeTerminal
.collectPaymentMethod(payment_intent_client_secret)
.then((StripePaymentIntent paymentIntent) {
print("A payment intent has captured a payment method, send this payment intent to you backend to capture the payment");
});
copied to clipboard
And you are done!!!!
