Usage

Initializing a Flutterwave instance

To create an instance, you should call the Flutterwave constructor. This constructor accepts a mandatory instance of the following:

• The calling Context
• publicKey
• Customer
• amount
• currency
• email
• fullName
• txRef
• isDebug
• paymentOptions
• Customization

It returns an instance of Flutterwave which we then call the async method .charge() on.

_handlePaymentInitialization() async { 
final style = FlutterwaveStyle(
 appBarText: "My Standard Blue", 
 buttonColor: Color(0xffd0ebff), 
 appBarIcon: Icon(Icons.message, color: Color(0xffd0ebff)),
 buttonTextStyle: TextStyle( 
     color: Colors.black, 
     fontWeight: FontWeight.bold, 
     fontSize: 18), 
appBarColor: Color(0xffd0ebff), 
dialogCancelTextStyle: TextStyle(
    color: Colors.redAccent, 
    fontSize: 18
    ),
dialogContinueTextStyle: TextStyle(
	    color: Colors.blue, 
	    fontSize: 18
	    ) 
	  ); 

final Customer customer = Customer(
	    name: "FLW Developer", 
	    phoneNumber: "1234566677777", 
	    email: "[email protected]"
	    );  
	    
final Flutterwave flutterwave = Flutterwave(
	    context: context, 
	    style: style, 
	    publicKey: "Public Key, 
	    currency: "RWF", 
	    redirectUrl: "my_redirect_url" 
	    txRef: "unique_transaction_reference", 
	    amount: "3000", 
	    customer: customer, 
	    paymentOptions: "ussd, card, barter, payattitude", 
	    customization: Customization(title: "Test Payment"),
	    isDebug: true
	    ); 
	} 

Handling the response

Calling the .charge() method returns a Future of ChargeResponse which we await for the actual response as seen above.

 final ChargeResponse response = await flutterwave.charge(); 
 if (response != null) { 
     print(response.toJson()); 
	 if(response.success) { 
	 Call the verify transaction endpoint with the transactionID returned in `response.transactionId` to verify transaction before offering value to customer 
	 } else { 
	  // Transaction not successful 
	} 
 } else {
  // User cancelled 
 }

Note

1. ChargeResponse can be null if a user cancels the transaction by pressing back.
2. You need to confirm the transaction is succesful. Ensure that the txRef, amount, and status are correct and successful. Be sure to verify the transaction details before providing value.
