I am currently using flutter web and I already have an html button that I want to add inside my flutter app. This html contains a java script as its body. How to add the html with javascript as a widget inside my app? This is the html snippet:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
<title>Paytabs Express Checkout V4</title>
</head>
<body>
<script
src=".js"
id="paytabs-express-checkout"
data-secret-key="key"
data-ui-type="button"
data-merchant-id="mid"
data-url-redirect="/"
data-amount="3.3"
data-currency="SAR"
data-title="John Doe"
data-product-names="click"
data-order-id="25"
data-ui-show-header="true"
data-customer-phone-number="5486253"
data-customer-email-address="[email protected]"
data-customer-country-code="973"
data-ui-show-billing-address="false"
data-billing-full-address="test test test"
data-billing-city="test"
data-billing-state="test"
data-billing-country="BHR"
data-billing-postal-code="123"
></script>
<script>
</script>
</body>
</html>
Hope you provide me with some help.

Reset to default 13You can go something like this. You should put your html releated code in index.html file and in src you need to put a path for your index.html e.g. 'assets/index.html'
import 'dart:html' as html;
import 'dart:js' as js;
import 'dart:ui' as ui;
String viewID = "your-view-id";
@override
Widget build(BuildContext context) {
// ignore: undefined_prefixed_name
ui.platformViewRegistry.registerViewFactory(
viewID,
(int id) => html.IFrameElement()
..width = MediaQuery.of(context).size.width.toString()
..height = MediaQuery.of(context).size.height.toString()
..src = 'path/to/your/index.html'
..style.border = 'none');
return SizedBox(
height: 500,
child: HtmlElementView(
viewType: viewID,
),
);
}
If I understand correctly, your intention is to be able to render your html/javascript as a native widget in flutter.
Unfortunately, I don't think this is technically possible due to the fact that flutter is rendering everything in its own light-weight rendering engine, rather than creating native code that your native runtime executes. The artifact(s) created (even in flutter web) after compilation is a combination of flutter runtime + your compiled code that executes on flutter runtime. Therefore this is not possible to add html/javascript to your flutter code as a widget and run it everywhere.
The solution is to implement your widget in pure Dart code.
You can use HtmlElementView for adding html elements inside a flutter web app https://api.flutter.dev/flutter/widgets/HtmlElementView-class.html
Beware that would only work in flutter web and
Embedding HTML is an expensive operation and should be avoided when a Flutter equivalent is possible
You should add this html content inside the file web/main.html.
I suggest you to build the button with Flutter and call javascript code with dart like this example calling javascript from Dart
