The thickness of the decoration stroke as a muliplier of the thickness defined by the font.
The font provides a base stroke width for decorations which scales off of the fontSize. This property may be used to achieve a thinner or thicker decoration stroke, without changing the fontSize. For example, a decorationThickness of 2.0 will draw a decoration twice as thick as the font defined decoration thickness.
Text( 'This has a very BOLD strike through!', style: TextStyle( decoration: TextDecoration.lineThrough, decorationThickness: 2.85, ), )
Text( 'oopsIforgottousespaces!', style: TextStyle( decoration: TextDecoration.underline, decorationStyle: TextDecorationStyle.wavy, decorationColor: Colors.red, decorationThickness: 0.5, ), )
The default decorationThickness is 1.0, which will use the font's base stroke thickness/width.
