Getting started #
Before you can use the plugin you have to setup a few things to implement the browser switch for iOS and Android:
ANDROID
1. Setup your scheme in AndroidManifest.xml under android > app > src > main > AndroidManifest.xml. This is needed because if the user starts the checkout process this plugin will switch to the browser and will open the checkout page of Mollie. After the checkout is done the browser will switch back to your app. The scheme will help the browser to open the correct app.
Modify your AndroidManifest.xml like the following. Be sure that you use an unique host and scheme name. The host and scheme are important in the next steps. We will use "payment-return" as host and "mollie" as scheme in this example.
<intent-filter>
<data
android:host="payment-return"
android:scheme="mollie" />
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
copied to clipboard
Your Manifest could look like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.plugon.mollie_example">
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here. -->
<application
android:name="io.flutter.app.FlutterApplication"
android:label="mollie_example"
android:icon="@mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<!-- This keeps the window background of the activity showing
until Flutter renders its first frame. It can be removed if
there is no splash screen (such as the default splash screen
defined in @style/LaunchTheme). -->
<meta-data
android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
android:value="true" />
<intent-filter>
<data
android:host="payment-return"
android:scheme="molli" />
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
</application>
</manifest>

2. Go to your MainActivity.java in android > app > src > java > com.yourcompany.appname > MainActivity and paste the follwing into it:
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
getFlutterView().pushRoute("paymentDone");
}
}
copied to clipboard
Change the route name to the route which you want to call after the payment process is done.
IMPORTANT
Currently this plugin supports only navigation with routes. Your MaterialApp() or CupertinoApp() widget should use the routes attribute to define routes. Otherwise this plugin will not process with the payment. You can ignore this step but then you have to process manually to the next step in your checkout process.
Your MainActivity could look like this:
public class MainActivity extends FlutterActivity {
boolean isSuccess;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
getFlutterView().pushRoute("paymentDone");
}
}
}
copied to clipboard
iOS
1. Open your AppDelegate.swift in xCode and past this into it:
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;
}
copied to clipboard
Be sure that the "payment-return" part equals your android:host in your AndroidManifest.xml.
IMPORTANT
Currently this plugin supports only navigation with routes. Your MaterialApp() or CupertinoApp() widget should use the routes attribute to define routes. Otherwise this plugin will not process with the payment. You can ignore this step but then you have to process manually to the next step in your checkout process.
2. Go to your Info.plist file. Right click any blank area and select Add Row to create a new key. (This part is from molli: https://docs.mollie.com/mobile-apps/getting-started-payments)
You’ll be prompted to select a key from a drop-down menu. Scroll to the bottom and select URL types. This creates an array item. You can further click the disclosure icon to expand it and you need to select Item 0. Expand that row as well and you should see URL identifier. Double-click the value field and fill in your identifier. Most of the time will this be the same as your bundle ID, e.g. com.mollie.MollieApp. Click on the plus-button next to Item 0 and choose URL Schemes from the drop-down menu. Expand the URL Schemes row and another Item 0 will show up. Type in the value-field the scheme you want to handle, in our case mollie-app. Make sure to pick a unique scheme.
USING THE PLUGIN #
The MollieCheckout widget works with the client method and the client-server method.
We will show you both implementations. If you want to use the client method step over this
step an go to "Getting started to use the plugin".
If you are using a client-server architecture you have to setup your server first for example with heroku.
In the following example we will use Node.js with Express.js to do our API calls.
1. After you setup your Node.js server you have to install the Mollie package. Go into your working directory and type:
npm install @mollie/api-client@beta --save

For detailed instructions go to https://github.com/mollie/mollie-api-node
2. Initialize Mollie:
const { createMollieClient } = require('@mollie/api-client');
const mollieClient = createMollieClient({ apiKey: 'test_AFkJP7UuC3wddaeGasdG2UffGTdkmd8re'});
copied to clipboard
You can find your API test and public keys in your Mollie Dashboard under the developer tab.
3. Create an order:
const { createMollieClient } = require('@mollie/api-client');
const mollieClient = createMollieClient({ apiKey: 'test_AFkJP7UuC3wddaeGasdG2UffGTdkmd8re'});
app.post("/your/custom/path",(req,res) => {
mollieClient.orders.create(req.body).then(order => {
res.send(order);
}).catch(error => {
res.send(error);
});
});

Getting started to use the plugin #
1. Import the plugin
import 'package:mollie/mollie.dart';
copied to clipboard
2. Create a new MollieOrderRequest:
MollieOrderRequest requestOrder = new MollieOrderRequest(
amount: MollieAmount(
value: "1396.00",
currency: "EUR"
),
orderNumber: "900",
redirectUrl: "mollie://payment-return",
locale: "de_DE",
webhookUrl: 'https://example.org/webhook',
billingAddress: new MollieAddress(
organizationName: 'Mollie B.V.',
streetAndNumber: 'Keizersgracht 313',
city: 'Amsterdam',
region: 'Noord-Holland',
postalCode: '1234AB',

]
);

3. IMPORTANT Setup the redirectUrl attribute in your MollieOrderRequest.
MollieOrderRequest order = new MollieOrderRequest(
...
redirectUrl: "mollie://payment-return",
...
);
copied to clipboard
The redirectUrl should follow this pattern scheme://host. For our example it should be mollie://payment-return.
Cheat Sheet:
(We use mollie and payment-return in this example)
File
Scheme
Host
RedirectUrl
AndroidManifest
android:scheme="mollie"
android:host="payment-return"
mollie://payment-return
Info.plist
URL Schemes -> item0 -> "mollie"
Set up "payment-return" in AppDelegate.swift (see top)
mollie://payment-return
4. Call your api endpoint or use the client instance to send your MollieOrderRequest to the server to retrieve an order object:
For client-server architecture:
Future<void> createOrder(MollieOrderRequest order) async{
/// send a POST request to your server with the created MollieOrderRequest
var orderResponse = await http.post(
"http://yourserver.herokuapp.com/mollie/create/order",
headers: {"Content-Type": "application/json"},
body: order.toJson()
);
/// get a order object from your server and parse it
var data = json.decode(orderResponse.body);
MollieOrderResponse res = MollieOrderResponse.build(data);
/// set the current order to retrieve this order from other widgets easily with Mollie.getCurrentOrder()
Mollie.setCurrentOrder(res);
/// Start the checkout process with the browser switch
Mollie.startPayment(res.checkoutUrl);
}
copied to clipboard
For calling directly from client. The client.init() function has to be called only once:
Future<void> createOrder(MollieOrderRequest order) async{
client.init("test_TUIAGS980q2ezahdoas");
var createdOrder = await client.orders.create(order);
/// set the current order to retrieve this order from other widgets easily with Mollie.getCurrentOrder()
Mollie.setCurrentOrder(createdOrder);
/// Start the checkout process with the browser switch
Mollie.startPayment(createdOrder.checkoutUrl);
}
copied to clipboard
5. Use the MollieCheckout widget to show nicely multiple payment methods:
@override
Widget build(BuildContext context) {
return MollieCheckout(
order: requestOrder,
onMethodSelected: (order) {
createOrder(order);
},
useCredit: true,
usePaypal: true,
useSepa: true,
useSofort: true,
useIdeal: true,
useApplePay: true
);
}
copied to clipboard
6. Optionally you can enable other payment methods. PayPal and Creditcard payment is enabled by default.
Currently supported payment methods:
CreditCard
Paypal
SEPA
Klarna Sofort
Apple Pay
iDEAL
PROFIT! :)
