grade property Null safety
The grade (granular stroke weight) for drawing the icon.
Requires the underlying icon font to support the
axis, otherwise has no effect. Variable font filenames often indicate
the supported axes. Can be negative.
Grade and weight both affect a symbol's stroke weight (thickness), but grade has a smaller impact on the size of the symbol.
Grade is also available in some text fonts. One can match grade levels between text and symbols for a harmonious visual effect. For example, if the text font has a -25 grade value, the symbols can match it with a suitable value, say -25.
Defaults to nearest IconTheme's IconThemeData.grade.
- fill, for controlling fill.
- weight, for controlling stroke weight in a less granular way.
- opticalSize, for controlling optical size.
