leading property
final
The additional leading to apply to the strut as a multiple of fontSize, independent of height and leadingDistribution.
Leading is additional spacing between lines. Half of the leading is added to the top and the other half to the bottom of the line. This differs from height since the spacing is always equally distributed above and below the baseline, regardless of leadingDistribution.
The default leading is null, which will use the font-specified leading.
Implementation
final double? leading;
