static init() {
  MediaQueryData mediaQuery = MediaQueryData.fromWindow(window);
  _screenWidth = mediaQuery.size.width;
  _screenHeight = mediaQuery.size.height;
  _stautsBarHeight = mediaQuery.padding.top;

  ///TODO:疑难杂症:这里为什么有时候会等于0，常见于点击搜索后，弹窗键盘,回来发现
  _screenBottomHeight = mediaQuery.padding.bottom;
