Mercado Pago's Unofficial Flutter checkout library

Made with ❤️ by Ricardo Markiewicz // @gazeria.

What is this? #

Flutter implementation of MercadoPago Mobile Checkout

Before to start #

This is a Work in progress project!, so please use with care and report the issues and feature request to our Github page. Thanks!

Getting Started #

  • Create an account in MercadoPago, you may need to choose the country where you want to accept payments.
  • Create an Application
  • Go to the credentials page (the url may change depending the country, but looks like and get the Public Key of the new app ** SECURITY WARNING: Do not use the Access Token, ClientID or Client Secret in your mobile application.
  • Call your backend to create a Checkout Preference and get a PreferenceId ** TODO: Add more documentation about preferences
  • In your Flutter code, call MercadoPagoMobileCheckout.startCheckout() to allow the user to pay
  • Save the payment response into your database.

Setup #

Android #

Nothing special to do, just add the plugin and use it.

iOS #

At the moment we need to setup a UINavigationController manually because the one that Flutter provides do not work with MercadoPago px-ios.

You need to setup your root view controller as UINavigationController in your AppDelegate of the ios folder of your app:

// AppDelegate.swift

import UIKit
import Flutter

@objc class AppDelegate: FlutterAppDelegate {
  var navigationController: UINavigationController?;

  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    // Add this line before GeneratedPluginRegistrant
    let flutterViewController: FlutterViewController = window?.rootViewController as! FlutterViewController

    // This line is added by the Flutter App Generator
    GeneratedPluginRegistrant.register(with: self)

    // Add these lines after GeneratedPluginRegistrant
    self.navigationController = UINavigationController(rootViewController: flutterViewController);
    self.navigationController?.setNavigationBarHidden(true, animated: false);

    self.window = UIWindow(frame: UIScreen.main.bounds);
    self.window.rootViewController = self.navigationController;
    // End of edit

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
