FontFeature.alternative constructor

const FontFeature.alternative(int value)

Access alternative glyphs. (aalt)

This feature selects the given glyph variant for glyphs in the span.

{@tool sample} The Raleway font supports several alternate glyphs. The code below shows how specific glyphs can be selected. With aalt set to zero, the default, the normal glyphs are used. With a non-zero value, Raleway substitutes small caps for lower case letters. With value 2, the lowercase "a" changes to a stemless "a", whereas the lowercase "t" changes to a vertical bar instead of having a curve. By targeting specific letters in the text (using widgets.Text.rich), the desired rendering for each glyph can be achieved.

** See code in examples/api/lib/ui/text/font_feature.font_feature_alternative.0.dart ** {@end-tool}
