最佳答案

To apply strikethrough decoration to a Text widget directly:

Text('\$8.99', style: TextStyle(decoration: TextDecoration.lineThrough))

You can also style separate spans of a paragraph by using the RichText widget, or the Text.rich() constructor.

Based on this example code, to show a discounted price:

`RichText()`

new RichText(
text: new TextSpan(
text: 'This item costs ',
children: <TextSpan>[
new TextSpan(
text: '\$8.99',
style: new TextStyle(
color: Colors.grey,
decoration: TextDecoration.lineThrough,
),
),
new TextSpan(
text: ' \$3.99',
),
],
),
)

`Text.rich()`

Text.rich(TextSpan(
text: 'This item costs ',
children: <TextSpan>[
new TextSpan(
text: '\$8.99',
style: new TextStyle(
color: Colors.grey,
decoration: TextDecoration.lineThrough,
),
),
new TextSpan(
text: ' \$3.99',
),
],
),
)
