The Dial is similar to a traditional dial knob that is found on devices such as stereos or industrial equipment. It allows the user to specify a value within a range.
像 CircularGauge , Dial can display tickmarks to give an indication of the current value. When a suitable stepSize is combined with tickmarkStepSize , the dial "snaps" to each tickmark.
You can create a custom appearance for a Dial by assigning a DialStyle .
