How to Convert/Show HTML as Widget in Flutter
Introduction
———-
Displaying HTML content in a Flutter application can be a challenging task, especially for developers who are new to the framework. However, there are several ways to convert and show HTML as a widget in Flutter. In this article, we will explore the different methods and provide a step-by-step guide on how to achieve this.
Adding HTML to Flutter
To add HTML to a Flutter application, you will need to use a package called `flutterhtml` or `html` widget. The `flutterhtml` package provides a simple way to render HTML content as a widget.
Installing the Package
To use the `flutter_html` package, you need to add it to your project’s `pubspec.yaml` file. Here is an example of how to do it:
“`yml
dependencies:
flutter_html: ^3.0.0-alpha.1
“`
Using the Package
Once you have added the package to your project, you can use it to render HTML content as a widget. Here is an example of how to use it:
“`dart
import ‘package:flutter/material.dart’;
import ‘package:flutterhtml/flutterhtml.dart’;
class HtmlExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
String htmlString = ‘
Hello, world!
‘;
return Scaffold(
appBar: AppBar(
title: Text(‘HTML Example’),
),
body: Html(
data: htmlString,
),
);
}
}
“`
Customizing the HTML Widget
You can customize the HTML widget by using the `customRender` property. This allows you to define a custom render for specific HTML tags. Here is an example of how to do it:
“`dart
Html(
data: htmlString,
customRender: {
‘p’: (context, child) => Padding(
padding: const EdgeInsets.all(16.0),
child: child,
),
},
)
“`
Handling Errors
When rendering HTML content, errors can occur. You can handle these errors by using the `onError` property. Here is an example of how to do it:
“`dart
Html(
data: htmlString,
onError: (exception) {
print(‘Error rendering HTML: $exception’);
},
)
“`
