First you have to use the Material
widget and within it you define a RichText
, TextSpan
and a Text
.
Inside the Material
widget you need to set underline color.
Material(
child:RichText(),//input our need
);
You can use decorationColor: yourColor inside your Text attribute to change the underline's color. For example, if you want to underline all of your text:
Text("Your text",
style: TextStyle(
color: Colors.white
decoration: TextDecoration.underline,
decorationColor: Colors.yellow,
))
In case you want to underline only a part of text you have to use RichText with TextSpan. For example:
RichText(
text: TextSpan(
children: [
TextSpan(
text: "NOT UNDERLINED TEXT",
style: TextStyle(
color: Colors.white)
),
TextSpan(
text: "UNDERLINED TEXT",
style: TextStyle(
color: Colors.white
decoration: TextDecoration.underline,
decorationThickness: 2,
decorationStyle: TextDecorationStyle.wavy))
],
style: TextStyle(color: Colors.yellow)
))
You can achieve this behaviour with a RichText .
RichText(
text: TextSpan(
text: 'You should only use this app when it is safe and legal to do so. ',
style: TextStyle(color: Colors.white),
children: [
TextSpan(
text: 'Please read our ',
style: TextStyle(
color: Colors.white,
),
children: [
TextSpan(
text: 'Privacy Policy',
style: TextStyle(
decoration: TextDecoration.underline,
decorationColor: Colors.yellow,
fontWeight: FontWeight.bold,
color: Colors.white,
),
)
],
),
],
),
);
