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
  • email
  • fullName
  • txRef
  • isTestMode
  • paymentOptions
  • redirectUrl
  • Customization

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

_

handlePaymentInitialization() async { 
	 final Customer customer = Customer(
	 name: "Flutterwave Developer",
	 phoneNumber: "1234566677777",   
     email: "customer@customer.com"  
 );            
    final Flutterwave flutterwave = Flutterwave(
        context: context, publicKey: "Public Key-here",
		currency: "currency-here",   
        redirectUrl: "add-your-redirect-url-here",  
        txRef: "add-your-unique-reference-here",   
        amount: "3000",   
        customer: customer,   
        paymentOptions: "ussd, card, barter, payattitude",   
        customization: Customization(title: "My Payment"),
        isTestMode: 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();

Call the verify transaction endpoint with the transactionID returned in response.transactionId or the txRef you provided to verify transaction before offering value to customer

Note

  • ChargeResponse can be null, depending on if the user cancels the transaction by pressing back.
  • You need to confirm the transaction is successful. Ensure that the txRef, amount, and status are correct and successful. Be sure to verify the transaction details before providing value.
  • Some payment methods are not instant, such a Pay with Bank Transfers, Pay with Bank, and so you would need to rely on webhooks or call the transaction verification service using the transactionId, or transaction reference you created(txRef)
  • For such long payments like the above, closing the payment page returns a cancelled status, so your final source of truth has to be calling the transaction verification service.
