Missing required param: amount

[xXxjubeixXx]

When I try to make a payment using the Stripe on Flutter, It returns me it when I click payment button.

{
  "error": {
    "code": "parameter_missing",
    "doc_url": "https://stripe.com/docs/error-codes/parameter-missing",
    "message": "Missing required param: amount.",
    "param": "amount",
    "request_log_url": "https://dashboard.stripe.com/logs/req_W9sWYIY9k2WjCe?t=1712157874",
    "type": "invalid_request_error"
  }
}

So, this is my main code:

//main.dart
import "homescreen.dart";
import "package:flutter/material.dart";
import "package:flutter_stripe/flutter_stripe.dart";

void main() async{
  WidgetsFlutterBinding.ensureInitialized();

  Stripe.publishableKey = "***";

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomeScreen(),
    );
  }
}

The homescreen code

// homescreen.dart
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:flutter_stripe/flutter_stripe.dart';
import "package:http/http.dart" as http;

class HomeScreen extends StatefulWidget {
  const HomeScreen({super.key});

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {

  Map<String, dynamic>? paymentIntent;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Who is the Rich"),
      ),
      body: Center(
        child: TextButton(
          onPressed: () {
            payment();
          },
          child: Text("Send Money!"),
        ),
      ),
    );
  }
  
  Future<void> payment() async {
    try{

      Map<String, dynamic> body = {
        "amount": 0.1,
        "currency": "BRL"
      };
      var authorization = "Bearer ***";
      var response = await http.post(
        Uri.parse("https://api.stripe.com/v1/payment_intents"),
        headers: {
          "Authorization": authorization,
          "Content-type": "application/json",
        }
      );
      paymentIntent = json.decode(response.body);
    }catch (error){
      throw Exception(error);
    }

    await Stripe.instance.initPaymentSheet(paymentSheetParameters: SetupPaymentSheetParameters(
      paymentIntentClientSecret: paymentIntent!["client_secret"],
      style: ThemeMode.system,
      merchantDisplayName: "Indigo",
    )).then((value) => {});

    try{
      await Stripe.instance.presentPaymentSheet().then((value) => {
        print("Payment Sucess!")
      });
    }catch (error){
      throw Exception(error);
    }
  }
}

I just need to make a payment on Stripe

@xXxjubeixXx you leaked your publishable and secret key. I recommend revoking and changing them asap.

I think you have to pass an amount of more than 1 BRL and multiply your amount with 100
