Declaration 宣言

The selected value within bounds.

bounds

The range of the valid values. Defaults to 0...1.

step

The distance between each valid value.

The slider calls onEditingChanged when editing begins and ends. For example, on iOS, editing begins when the user starts to drag the thumb along the slider’s track.
