使用第三方依赖 flutter_screenutil

使用

import 'package:flutter_screenutil/flutter_screenutil.dart';
void main() {
  runApp(
    ScreenUtilInit( // 嵌套主组件
      designSize: const Size(1194, 834), // 设计稿的宽度和高度
      minTextAdapt: true,
      splitScreenMode: true,
      builder:(context,child){ 
        return GetMaterialApp(
          title: "Application",
          defaultTransition:Transition.rightToLeft,
          initialRoute: AppPages.INITIAL,
          getPages: AppPages.routes,
        );
      }
    )
  );
}

在组件中使用

import 'package:flutter_screenutil/flutter_screenutil.dart';
​
class MyScreenUtil {
  static width(num val){return val.w;}
  static height(num val){return val.h;}
  static fontSize(num val){return val.sp;}
  static radius(num val){return val.r;}
  static getScreenWidth(){return 1.sw;}// 获取屏幕高度
  static getScreenHeight(){return 1.sh;} // 获取屏幕宽度
  static getStatusBarHeight(){
    return ScreenUtil().statusBarHeight;
  }
}
