app直播源代码，Flutter 宽高自适应

app直播源代码，Flutter 宽高自适应

工具类代码如下：

 

1

<br>import 'dart:ui';<br>class HYSizeFit {<br>  static double screenWidth = 0.0;<br>  static double screenHeight = 0.0;<br>  static double physicalWidth = 0.0;<br>  static double physicalHeight = 0.0;<br>  static double dpr = 0.0;<br>  static double statusHeight = 0.0;<br>  static double rpx = 0.0;<br>  static double px = 0.0;<br>  static void initialize({double standardSize = 750}) {<br>    // 1、手机的物理分辨率<br>    physicalWidth = window.physicalSize.width;<br>    physicalHeight = window.physicalSize.height;<br>    // 2、 获取dpr<br>    dpr = window.devicePixelRatio;<br>    // 3、宽度和高度<br>    screenWidth = physicalWidth / dpr;<br>    screenHeight = physicalHeight / dpr;<br>    // 4、 状态栏高度<br>    statusHeight = window.padding.top / dpr;<br>    // 5、计算 rpx 的大小<br>    rpx = screenWidth / standardSize;<br>    px = screenWidth / standardSize * 2;<br>  }<br>// 按照像素来设置<br>  static double setPx(double size) {<br>    return px * size;<br>  }<br>// 按照rpx来设置<br>  static double setRpx(double size) {<br>    return rpx * size;<br>  }<br>}

​

扩展(extension)代码

 

1

<br>import 'hysize.dart';<br>extension DoubleFit on double {<br>  double get px {<br>    return HYSizeFit.setPx(this);<br>  }<br>  double get rpx {<br>    return HYSizeFit.setRpx(this);<br>  }<br>}<br>extension IntFit on int {<br>  double get px {<br>    return HYSizeFit.setPx(toDouble());<br>  }<br>  double get rpx {<br>    return HYSizeFit.setRpx(toDouble());<br>  }<br>}
