Error on clicking payment method (Flutter android)

[akashrajkn]

Hi,

First of all, thank you for making the plugin :)

Mollie version: v0.8.1
Flutter: 1.9.1+hotfix.2

I am able to display the widget. However, when I click a payment method, I get the following error:

E/flutter (30468): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: NoSuchMethodError: The method '[]' was called on null.
E/flutter (30468): Receiver: null
E/flutter (30468): Tried calling: []("currency")
E/flutter (30468): #0      Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5)
E/flutter (30468): #1      new MollieOrderResponse.build (package:mollie/src/mollieorder.dart:79:33)
E/flutter (30468): #2      OrderHandler.create (package:mollie/internal/orderhandler.dart:24:32)
E/flutter (30468): <asynchronous suspension>

How do I resolve this?

Hi akashrajkn thanks for your request :)
I couldn't recreate your issue. Can you explain your issue more in detail? So when I understand it correctly you are using the MollieCheckout widget right? And It looks like you are using the client method, so you are calling the api directly from your app? Please add your code to your answer.

@Oni22 Sorry for the late reply. Yes, I am using the client method. I am using the example code from the readme (this was just to make sure browser redirect works). But on clicking a payment type, I get the above error.

hi ....
can you be more informative how to add this to appdelagate.swift in flutter ..
my app is having a adaptive platform..
i want to integrate ideal payment feature...

override func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
if (url.host! == "payment-return") {

        let controller : FlutterViewController = window?.rootViewController as! FlutterViewController
        controller.pushRoute("paymentDone");

        return true;
    }

    return false;
}

this code,

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)

}

}

is already there in my appdelagate.swift file ..how to go about

It is because your MollieProductRequest has Missing Fields or are incorrect. The Response is an error, but this Framework does not do any error handling so this Framework always thinks it getting a success Response.
Im facing this problem right now too.

Do a this:

`Future create(MollieOrderRequest order) async {
var res =
await http.post(_apiEndpoint, headers: _headers, body: order.toJson());

print(res.body); // <---- add this line to get all errors from Mollie
return MollieOrderResponse.build(json.decode(res.body));

}`
