Code Snapshot Details

To generate refresh token using clientkey and clientsecret, you can use generateRefreshToken method which is return json object.

sadadPay.generateRefreshToken(clientKey: _clientKey, clientSecret: _clientSecret).then(
        (value) => _refreshToken = value['response']['refreshToken']);

To generate access token, you can use generateAccessToken method which is return json object.

sadadPay.generateAccessToken(refreshToken: _refreshToken).then(
        (value) => _accessToken = value['response']['accessToken']);

To create invoice, you can use createInvoice method which is return json object.

final invoices = {
    "Invoices": [
      {
        "amount": "10",
        "customer_Name": "customer",
        "customer_Email": "customer@example.com",
        "lang": "en",
        "currency_Code": "KWD",
        "items": [
          {"name": "x", "quantity": 2, "amount": 2},
          {"name": "y", "quantity": 6, "amount": 1}
        ]
      }
    ]
  };

sadadPay.createInvoice(invoices: invoices, token: _accessToken).then(
        (value) => setState(() => _invoiceId = value['response']['invoiceId']));

To get invoice by id, you can use getInvoice method which is return json object.

sadadPay.getInvoice(invoiceId: _invoiceId, token: _accessToken).then(
        (value) => setState(() => _invoiceKey = value['response']['key']));

To use sadad web view, use can use SadadWebView which is return widget.

 @override
  Widget build(BuildContext context) {
    if (_invoiceKey != '') {
      return SadadWebView(
        invoiceKey: _invoiceKey,
        onSuccess: () {
          Navigator.push(
            context,
            MaterialPageRoute(builder: (context) => const SuccessPage()),
          );
        },
        onFail: () {
          Navigator.push(
            context,
            MaterialPageRoute(builder: (context) => const FailPage()),
          );
        },
        appBar: AppBar(
          title: const Text('App Bar'),
        ),
      );
    } else {
      return const CircularProgressIndicator();
    }
  }
}
