Initialize (like ScreenUtilInit)

Wrap your app once:

import 'package:flutter/material.dart';
import 'package:mini_screen_util/mini_screen_util.dart';

void main() {
  runApp(
    MiniScreenInit(
      designSize: const Size(480, 800),
      // Optional:
      // allowSystemTextScale: true,
      // minTextScaleFactor: 1.0,
      // maxTextScaleFactor: 1.15,
      child: const MyApp(),
    ),
  );
}

---

Use .w/.h/.r/.sp (no context)

import 'package:flutter/material.dart';
import 'package:mini_screen_util/mini_screen_util.dart';

class DemoCard extends StatelessWidget {
  const DemoCard({super.key});

  @override
  Widget build(BuildContext context) {
    return Container(
      width: 240.w,
      height: 72.h,
      padding: EdgeInsets.all(12.r),
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(16.r),
        border: Border.all(width: 1.w),
      ),
      alignment: Alignment.center,
      child: Text(
        'Hello',
        style: TextStyle(fontSize: 18.sp),
      ),
    );
  }
}

Notes

• .sp uses width scaling + optional system textScaler.
• .r defaults to scaling using the shortest side.

Text scaling (Flutter TextScaler)

Flutter has deprecated textScaleFactor in favor of TextScaler. mini_screen_util uses MediaQuery.textScalerOf(context) under the hood and applies it in .sp.
