Methods

convertFontSize(num fontSize, {bool? allowFontScaling, bool? allowSubpixel}) → double

字体大小适配方法 @param fontSize UI设计上字体的大小,单位px. Font size adaptation method @param fontSize The size of the font on the UI design, in px. @param allowFontScaling

convertHeight(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.

convertWidth(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,比如你先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

init({double? width, double? height, bool? allowFontScaling, required bool allowSubpixel, double? maxWidth}) → ScreenScaleProperties

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
