Font class

Font style support for size, family, weight, style, variant, and lineheight.

Constructors

Font({num? size, List<String>? family, int? weight, String? style, String? variant, LineHeight? lineHeight})

Create a font using size of font in pixels, family name of font(s) using FontFamily, style of the font using FontStyle, variant using FontVariant, and lineHeight extra space (leading) around the font in pixels, if not specified it's 1.2 the font size.

const

Properties

cssExpression → String

Shorthand CSS format for font is:

no setter

family → List<String>?

Family specifies a list of fonts, the browser will sequentially select the the first known/supported font. There are two types of font families the family-name (e.g., arial, times, courier, etc) or the generic-family (e.g., serif, sans-seric, etc.)

final

hashCode → int

The hash code for this object.

no setter, override

lineHeight → LineHeight?

final

lineHeightInPixels → num?

The lineHeight, provides an indirect means to specify the leading. The leading is the difference between the font-size height and the (used) value of line height in pixels. If lineHeight is not specified it's automatically computed as 1.2 of the font size. Firefox is 1.2, Safari is ~1.2, and CSS suggest a ration from 1 to 1.2 of the font-size when computing line-height. The Font class constructor has the computation for _lineHeight.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → num?

final

style → String?
