Methods

deviceType(BuildContext context) → DeviceType
diagonal(num d) → double
Adapt according to the both width and height
diameter(num d) → double
Adapt according to the maximum value of scale width and scale height
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
radius(num r) → double
根据宽度或高度中的较小值进行适配 Adapt according to the smaller of width or height
setHeight(num height) → double
根据UI设计的设备高度适配 当发现UI设计中的一屏显示的与当前样式效果不符合时, 或者形状有差异时,建议使用此方法实现高度适配. 高度适配主要针对想根据UI设计的一屏展示一样的效果 Highly adaptable to the device according to UI Design It is recommended to use this method to achieve a high degree of adaptation when it is found that one screen in the UI design does not match the current style effect, or if there is a difference in shape.
setSp(num fontSize) → double
字体大小适配方法
setWidth(num width) → double
根据UI设计的设备宽度适配 高度也可以根据这个来做适配可以保证不变形,比如你想要一个正方形的时候. Adapted to the device width of the UI Design. Height can also be adapted according to this to ensure no deformation , if you want a square
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
