About

Please note that this library is no more supported, and so no updates would be published. 
You can find the new, supported library [here](https://pub.dev/packages/flutterwave_standard) 

Flutterwave's Flutter SDK is Flutterwave's offical flutter sdk to integrate the Flutterwave payment into your flutter app. It comes with a readymade Drop In UI.
The payment methods currently supported are Cards, USSD, Mpesa, GH Mobile Money, UG Mobile Money, ZM Mobile Money, Rwanda Mobile Money, Franc Mobile Money and Nigeria Bank Account.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
See references for links to dashboard and API documentation.

Requirements

• Ensure you have your test (and live) API keys.
• This Library runs and the V3 API, and so you need to be PCI-DSS certified to use this.

Flutter version >= 1.17.0  
Flutterwave version 3 API keys  

Installation

Add the dependency

In your pubspec.yaml file add:

1. flutterwave: 1.0.2
2. run flutter pub get

Usage

1. Create a Flutterwave instance

Create a Flutterwave instance by calling the constructor Flutterwave.forUIPayment() The constructor accepts a mandatory instance of the following:
the calling Context , publicKey, encryptionKey, amount, currency, email, fullName, txRef, isDebugMode and phoneNumber . It returns an instance of Flutterwave which we then call the async method .initializeForUiPayments() on.

    beginPayment async () {      
 try {   
        Flutterwave flutterwave = Flutterwave.forUIPayment(  
			context: this.context, 
			encryptionKey: "Your_test_encryption_key_here", 
			publicKey: "Your_test_public_key_here", 
			currency: currency, 
			amount: amount, 
			email: "valid@email.com", 
			fullName: "Valid Full Name", 
			txRef: txref, 
			isDebugMode: true, 
			phoneNumber: "0123456789", 
			acceptCardPayment: true, 
			acceptUSSDPayment: false, 
			acceptAccountPayment: false, 
			acceptFrancophoneMobileMoney: false, 
			acceptGhanaPayment: false, 
			acceptMpesaPayment: false, 
			acceptRwandaMoneyPayment: true, 
			acceptUgandaPayment: false, 
			acceptZambiaPayment: false)              
	final ChargeResponse response = awaitflutterwave.initializeForUiPayments();  
             } catch(error) {  
 handleError(error); }  

2. Handle the response Calling the .initialiazeForUiPayments() method returns a Future

of ChargeResponse which we await for the actual response as seen above. An example of how to make payment in a Widget would look like this:

class PaymentWidget extends StatefulWidget { 

@override 
_PaymentWidgetState createState() => _PaymentWidgetState(); 

} 

class _PaymentWidgetState extends State<PaymentWidget> {  
    final String txref = "My_unique_transaction_reference_123";
    final String amount = "200"; 
    final String currency = FlutterwaveCurrency.RWF; 
    
    @override  
    Widget build(BuildContext context) { 
    return Container(); 
    } 
    
    beginPayment() async {  
    final Flutterwave flutterwave = Flutterwave.forUIPayment( context: this.context, 
    encryptionKey: "your_test_encryption_key", 
    publicKey: "your_public_key", 
    currency: this.currency, 
    amount: this.amount, 
    email: "[valid@email.com](mailto:valid@email.com)", 
    fullName: "Valid Full Name", 
    txRef: this.txref, 
    isDebugMode: true, 
    phoneNumber: "0123456789", 
    acceptCardPayment: true, 
    acceptUSSDPayment: false, 
    acceptAccountPayment: false, 
    acceptFrancophoneMobileMoney: false, 
    acceptGhanaPayment: false, 
    acceptMpesaPayment: false, 
    acceptRwandaMoneyPayment: true, 
    acceptUgandaPayment: false, 
    acceptZambiaPayment: false); 
    
    try {  
    final ChargeResponse response = await flutterwave.initializeForUiPayments(); 
    if (response == null) { 
    // user didn't complete the transaction.
     } else { 
         final isSuccessful = checkPaymentIsSuccessful(response); 
         if (isSuccessful) {
          // provide value to customer 
          } else { 
          // check message print(response.message); 
          // check status  
	        print(response.status); // check processor error  
	        print(response.data.processorResponse); 
		    } 
	    } 
    } catch (error, stacktrace) {
     // handleError(error); 
         } 
     } 
     bool checkPaymentIsSuccessful(final ChargeResponse response){  
    return response.data.status == FlutterwaveConstants.SUCCESSFUL
    && response.data.currency == this.currency 
    && response.data.amount == this.amount 
    && response.data.txRef == this.txref; 
        } 
    }

Please note that:

• ChargeResponse can be null, depending on if the user cancels
  the transaction by pressing back.
• You need to check the status of the transaction from the instance of ChargeResponse returned from calling .initializeForUiPayments(), the amount, currency and txRef are correct before providing value to the customer
• To accept payment of different kinds, you need set the currency to the correspending payment type i.e, KES for Mpesa, RWF for Rwanda Mobile Money, NGN for USSD,
  Bank Accounts Payment and so on.>

PLEASE NOTE We advise you to do a further verification of transaction's details on your server to be sure everything checks out before providing service or goods as seen in the checkPaymentIsSuccessful() method above.
