Installing

dependencies:
  invoiceninja: ^0.0.3

Import

import 'package:invoiceninja/invoiceninja.dart';

Configure

The InvoiceNinja class provides an SDK for the Invoice Ninja /shop routes which support reading the list of products and creating/finding clients and invoices.

If each user of the app is accessing their own account you can use the InvoiceNinjaAdmin class to support editing records.

InvoiceNinja.configure(
  'demo', // Set your company key or use 'demo' to test
  url: 'https://demo.invoiceninja.com', // Set your selfhost app URL
  debugEnabled: true,
);

Load the product list

final products = await InvoiceNinja.products.load();

Find the product by key

final product = await InvoiceNinja.products.findByKey('product_key');

Create/persist the client

var client = Client.forContact(email: 'test@example.com');
client = await InvoiceNinja.clients.save(client);

Create/persist the invoice

var invoice = Invoice.forClient(client, products: [product]);
invoice = await InvoiceNinja.invoices.save(invoice);

Display the PDF invoice

launch(
  'https://docs.google.com/gview?embedded=true&url=${invoice.pdfUrl}',
  forceWebView: true,
);

Accept the payment

var invoiceKey = invoice.key;
launch(invoice.url);

// ...

final invoice = await InvoiceNinja.invoices.findByKey(invoiceKey);
if (invoice.isPaid) {
  // ...
}

You can use the WidgetsBindingObserver interface to run code when the app is resumed.

Consider giving issue #57536 a thumbs up to make this better in the future.

InvoiceNinjaAdmion.configure(
  'TOKEN', // Set your API token or use 'TOKEN' to test
