NamedLine class

Constructors

NamedLine({required String name, required Expression expression, Paint? paint, String? father, bool isGroup = false})

const

NamedLine.copy(NamedLine copy)

vertical 创建的是 vw horizental 创建的是 vh

factory

NamedLine.expression(Expression expression, {required String name, Size sample = const Size.square(1.0), Paint? paint, String? father})

表达式计算结果

factory

NamedLine.literal((double, PxUnit) value, {required String name, Paint? paint, String? father})

literal 和 percent 混合计算的结果值(使用expression代替) 支持 vh vw rpx 等相对单位值 以及 px 绝对值

factory

NamedLine.percent(double value, {required String name, Paint? paint, String? father})

factory

NamedLine.rename({required String rename, required NamedLine copy})

factory

NamedLine.repaint({required Paint repaint, required NamedLine copy})
