StrutStyle constructor

StrutStyle({String fontFamily, List<String> fontFamilyFallback, double fontSize, double height, double leading, FontWeight fontWeight, FontStyle fontStyle, bool forceStrutHeight })

Creates a new StrutStyle object.

  • fontFamily: The name of the font to use when painting the text (e.g., Roboto).

  • fontFamilyFallback: An ordered list of font family names that will be searched for when the font in fontFamily cannot be found.

  • fontSize: The size of glyphs (in logical pixels) to use when painting the text.

  • height: The minimum height of the line boxes, as a multiplier of the font size. The lines of the paragraph will be at least `(height + leading)

    • fontSize` tall when fontSize is not null. When fontSize is null, there is no minimum line height. Tall glyphs due to baseline alignment or large TextStyle.fontSize may cause the actual line height after layout to be taller than specified here. fontSize must be provided for this property to take effect.

  • leading: The minimum amount of leading between lines as a multiple of the font size. fontSize must be provided for this property to take effect.

  • fontWeight: The typeface thickness to use when painting the text (e.g., bold).

  • fontStyle: The typeface variant to use when drawing the letters (e.g., italics).

  • forceStrutHeight: When true, the paragraph will force all lines to be exactly (height + leading) * fontSize tall from baseline to baseline. TextStyle is no longer able to influence the line height, and any tall glyphs may overlap with lines above. If a fontFamily is specified, the total ascent of the first line will be the min of the Ascent + half-leading of the fontFamily and (height + leading) * fontSize. Otherwise, it will be determined by the Ascent + half-leading of the first text.

Implementation

StrutStyle({
  String fontFamily,
  List<String> fontFamilyFallback,
  double fontSize,
  double height,
  double leading,
  FontWeight fontWeight,
  FontStyle fontStyle,
  bool forceStrutHeight,
}) : _encoded = _encodeStrut(
       fontFamily,
       fontFamilyFallback,
       fontSize,
       height,
       leading,
       fontWeight,
       fontStyle,
       forceStrutHeight,
     ),
     _fontFamily = fontFamily,
     _fontFamilyFallback = fontFamilyFallback;
