Flutter - 获取屏幕大小 get screen window size 这两天又重新捡起来了Flutter,又遇到了一个问题。 我想一个Widget的宽高根据屏幕的宽高来调整,所以用到了一个获取屏幕的 window.physicalSize.height window.physicalSize.width 然后发现大小和市局预想的不一样。 所以后来换成了 MediaQuery.of(context).size.height...
3、配置 下面代码放在build方法里面 然后宽度高度和你的设计稿对应 ScreenUtil.instance=ScreenUtil(width:750,height:1334)..init(context); 4、这时候设置宽度高度的时候就可以用我们设计稿的宽度高度了 width:ScreenUtil.getInstance().setWidth(375),height:ScreenUtil.getInstance().setHeight(200), 5、Flutter如何...
