Font class abstract
Constructors
- Font()
Properties
- ascent → double
-
no setter
-
axes
→ Iterable<
FontAxis> -
no setter
- capHeight → double
-
Distances from the baseline to the top of capital / lowercase letters,
stored negative (up is -Y) like ascent. Both fall back to ascent when
the font does not provide the metric.
no setter
- descent → double

-
features
→ Iterable<
FontTag> -
no setter
- hasColorGlyphs → bool
-
Whether this font contains any COLR color glyphs (emoji).
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
