How to Underline Text in Flutter: A Complete Guide 🎯

So you want to underline text in Flutter, specifically inside the Text widget? You're in the right place! Whether you're a Flutter newbie or a seasoned developer, it's always good to have a clear understanding of how to achieve this simple yet crucial task. Let's dive in and explore the different methods to underline text in Flutter.

The Underline Text Dilemma ❓

You're probably wondering why the TextStyle's fontStyle property doesn't seem to have an underline option. Well, you're not alone! Flutter's TextStyle doesn't provide a direct way to underline text. However, fear not! There are a couple of workarounds that you can adopt to achieve the desired effect. Let's explore them one by one.

Workaround #1: Using the Container Widget 📦

One way to underline text in Flutter is by utilizing the Container widget. Here's how you can implement it:

Container(
  decoration: BoxDecoration(
    border: Border(
      bottom: BorderSide(
        color: Colors.black,   // Specify your desired underline color
        width: 1.0,           // Specify the underline thickness
      ),
    ),
  ),
  child: Text(
    "Your Underlined Text",
    style: TextStyle(
      fontSize: 16.0,  // Specify the desired font size
      color: Colors.black,   // Specify the desired text color
      // Any other desired text style properties
    ),
  ),
)

By using the Container widget and its decoration property, we create a border with a specified color and thickness at the bottom of the widget. This visually simulates underlining the text.

Workaround #2: Using the RichText Widget 🌈

Another approach to underline text in Flutter is by leveraging the RichText widget. Here's an example:

RichText(
  text: TextSpan(
    text: "Your Underlined Text",
    style: TextStyle(
      fontSize: 16.0,  // Specify the desired font size
      color: Colors.black,   // Specify the desired text color
      // Any other desired text style properties
    ),
    decorations: [
      TextDecoration.underline,
    ].map((decoration) {
      return TextDecorationStyle.solid;
    }).toList(),
  ),
)

Here, we use the RichText widget along with TextSpan to apply text decorations. By setting the decorations property to [TextDecoration.underline], we achieve the underlined effect. Adjust the font size, color, and any other desired text style properties to suit your needs.

Choose Your Underlining Method ✏️

Now that you've seen both workarounds, it's up to you to choose the best approach for your Flutter project. Both methods provide the desired underlining effect, but depending on your specific needs and the context in which you're applying the underline, one may be more suitable than the other.
