How to Create a Hyperlink in Flutter Widget? 🌐

Are you looking to add a hyperlink to your Flutter app? 📱💡 Creating a clickable link within a text can be a powerful way to share information and engage users. In this blog post, we'll explore how to easily create hyperlinks within Flutter widgets, such as Text, and provide simple solutions to common challenges. So, let's dive in!

The Problem 😫

The challenge lies in embedding a hyperlink within a Text widget or similar text views. The example provided in the question shows an attempt to create a hyperlink using HTML-like syntax:

The last book bought is <a href='#'>this</a>

However, Flutter does not support rendering HTML tags directly in its widgets. So, how can we achieve this desired hyperlink effect? Let's find out! 🕵️‍♂️

Solution 1: Using RichText 📝

Flutter provides us with the RichText widget, which offers more advanced text formatting options than the basic Text widget. It allows us to create custom-styled text spans, including hyperlinks. Here's how you can use RichText to create a hyperlink:

RichText(
  text: TextSpan(
    text: 'The last book bought is ',
    children: [
      TextSpan(
        text: 'this',
        style: TextStyle(
          color: Colors.blue,
          decoration: TextDecoration.underline,
        ),
        recognizer: TapGestureRecognizer()
        ..onTap = () {
          // Code to execute when the link is tapped
        },
      ),
    ],
  ),
)

In the above example, we define a TextSpan as a child of RichText. The TextSpan is responsible for rendering the hyperlink text ('this') with the desired style (TextStyle). We use the TapGestureRecognizer from the flutter/gestures.dart package to handle taps on the hyperlink, allowing us to execute custom code when the link is tapped.

Solution 2: Using the Link package 📦

If you prefer a more convenient solution, you can use the Link package, which simplifies the process of creating hyperlinks in Flutter. To use the Link package, follow these steps:

1. Add the link package to your pubspec.yaml file:

   dependencies: link: ^1.1.1

2. Import the package in your Dart file:

   import 'package:link/link.dart';

3. Wrap your hyperlink text with the Link widget:

   Link( child: Text('The last book bought is this'), url: '#', onError: (LinkError? error) { // Handle any errors that occur }, );

The Link widget takes a child argument, which can be any widget, and a url argument, which specifies the URL to navigate when the link is tapped. The onError callback allows you to handle any errors that occur during navigation.
