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.
