Quick Tip – How to use Text decoration in Flutter

What is Text decoration in Flutter

In Flutter, the Text widget allows you to customize the appearance of the text it displays through its style property. The TextStyle class, which is used to define the style for a Text widget, has a property called decoration which can be used to specify a decoration to be painted along with the text.

The decoration property is of type TextDecoration, which is an enum with the following values:

  • TextDecoration.none: No decoration is painted. This is the default value.
  • TextDecoration.underline: Paints an underline below the text.
  • TextDecoration.overline: Paints an overline above the text.
  • TextDecoration.lineThrough: Paints a line through the middle of the text.

You can use the TextDecoration enum to specify a single decoration, or you can use the TextDecoration.combine method to combine multiple decorations into a single value.

What is underline Textdecoration in Flutter

In Flutter, the TextDecoration.underline value of the TextDecoration enum specifies that an underline should be drawn below the text. This can be useful for indicating that the text is a link, or for emphasizing certain words or phrases.

To apply an underline to a Text widget in Flutter, you can use the decoration property of the TextStyle class, which is passed to the style property of the Text widget. Here is an example of how to do this:

What is TextDecorationStyle in Flutter

In Flutter, the TextDecorationStyle enum is used to specify the style of a decoration that is drawn by the Text widget. This enum is used in conjunction with the decoration and decorationStyle properties of the TextStyle class.

The TextDecorationStyle enum has the following values:

  • TextDecorationStyle.solid: A solid line is drawn. This is the default value.
  • TextDecorationStyle.double: Two lines are drawn, with some space in between.
  • TextDecorationStyle.dotted: A dotted line is drawn.
  • TextDecorationStyle.dashed: A dashed line is drawn.
  • TextDecorationStyle.wavy: A wavy line is drawn.

To specify the style of a decoration for a Text widget, you can set the decorationStyle property of the TextStyle class to one of the values of the TextDecorationStyle enum. Here is an example of how to do this:

            Text(
              'flutterassets.com',
              style: TextStyle(fontSize: 40, color: Colors.green,
                fontFamily: "Genos",
                fontWeight: FontWeight.w900,
                decoration: TextDecoration.underline,
                decorationColor: Colors.red,
                decorationThickness: 2,
                decorationStyle: TextDecorationStyle.dashed,
              ),
            ),



//decorationStyle: TextDecorationStyle.dashed,
//decorationStyle: TextDecorationStyle.dotted,
//decorationStyle: TextDecorationStyle.double,
//decorationStyle: TextDecorationStyle.wavy,
text decoration

Note that the decorationStyle property only affects decorations that are drawn using the underline, overline, or lineThrough values of the TextDecoration enum. If you set the decoration property to TextDecoration.none, the decorationStyle property will have no effect.
