Size getSize()

根据设置的宽度，来得到对应的高度

Implementation

static Size getSize() {
  // 如果是横屏就已宽度为基准

  var originalSize = window.physicalSize / window.devicePixelRatio;
  var originalWidth = originalSize.width;
  var originalHeight = originalSize.height;
  if (originalHeight > originalWidth) {
    // 竖屏
    _screenHeight = window.physicalSize.height / getDevicePixelRatio();
    _screenWidth = _screenStandard;
    _screenSize = Size(_screenStandard, _screenHeight);
    return _screenSize;
  } else {
    // 横屏
    _screenWidth = window.physicalSize.width / getDevicePixelRatio();
    _screenHeight = _screenStandard;
    _screenSize = Size(_screenWidth, _screenStandard);
    return _screenSize;
  }
