TextStyle createTextStyle(CSSRenderStyle renderStyle, { double? height, Color? color, })

Implementation

static TextStyle createTextStyle(CSSRenderStyle renderStyle, {double? height, Color? color}) {
  // Creates a new TextStyle object.
  //   color: The color to use when painting the text. If this is specified, foreground must be null.
  //   decoration: The decorations to paint near the text (e.g., an underline).
  //   decorationColor: The color in which to paint the text decorations.
  //   decorationStyle: The style in which to paint the text decorations (e.g., dashed).
  //   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).
  //   fontSize: The size of glyphs (in logical pixels) to use when painting the text.
  //   letterSpacing: The amount of space (in logical pixels) to add between each letter.
  //   wordSpacing: The amount of space (in logical pixels) to add at each sequence of white-space (i.e. between /// each word).
  //   textBaseline: The common baseline that should be aligned between this text span and its parent text span, /// or, for the root text spans, with the line box.
  //   height: The height of this text span, as a multiple of the font size.
  //   locale: The locale used to select region-specific glyphs.
  //   background: The paint drawn as a background for the text.
  //   foreground: The paint used to draw the text. If this is specified, color must be null.
  // Respect visibility:hidden: do not paint text or its decorations but keep layout.
