### DeviceUtil
1. 界面适配的尺寸计算，应该在 didChangeMetrics 时再次调用，保证屏幕适配参数是最新的

   ```
    @override
     void didChangeMetrics() {
       super.didChangeMetrics();
       final pixelRatio = window.devicePixelRatio;
       //宽度
       final width = window.physicalSize.width;
       //高度
       final height = window.physicalSize.height;
       print('HeadbandEntry, pixelRatio = $pixelRatio');
       print('HeadbandEntry, width = $width');
       print('HeadbandEntry, height = $height');
       Devices.init(width: 1080, height: 805);
     }
   ```
   ```
   使用的地方可以使用Devices().pixelRatio来调用
   ```
