使用 "opacityDecayVelocity" 属性配置 paper-ripple
Configuring paper-ripple with "opacityDecayVelocity" attribute
纸波纹动画的默认时间设置为0.8s，使过渡看起来较慢。
尝试通过更改值：
<paper-ripple opacityDecayVelocity ="1.0"></paper-ripple>
添加 $ 作为其属性
<paper-ripple opacityDecayVelocity$ ="1.0"></paper-ripple>
None 似乎有效。请提出配置属性值的方法。
属性名应该是opacity-decay-velocity
<paper-ripple opacity-decay-velocity="1.0" ></paper-ripple>
Attribute names with dashes are converted to camelCase property names
by capitalizing the character following each dash, then removing the
dashes. For example, the attribute first-name maps to firstName.
The same mappings happen in reverse when converting property names to attribute names
