  AppSize(

Whenever you use height and width first import AppSize package.

import 'package:appsize/appsize.dart';

Widget Size 🕓

    Container(
      width: 20.w,    //It will take a 20% of screen width
      height:30.h     //It will take a 30% of screen height
    )

Padding ⏹

    Padding(
      padding: EdgeInsets.symmetric(
        vertical: 15.sp,    //It will use 15 sizeables pixels  
        horizontal: 30.sp,  //It will use 30 sizeables pixels 
      ),
      child: Container(),
    );

Font size 🆎

    Text(
      'AppSize',
      style: TextStyle(
        fontSize: 15.sp,
      ),
    );

Square Widget 🟩

If you want to make square size widget then give height or width in both height and width.

    Container(
      width: 30.h,      //It will take a 30% of screen height
      height: 30.h,     //It will take a 30% of screen height
    );

Orientation 🔄

If you want to support both portrait and landscape orientations

Device.orientation == Orientation.portrait
  ? Container(   // Widget for Portrait
      width: 100.w,
      height: 20.5.h,
   )
  : Container(   // Widget for Landscape
      width: 100.w,
      height: 12.5.h,
   )

DeviceType 📱

If you want the same layout to look different in tablet and mobile, use the AppSizeUtil.deviceType method:

AppSizeUtil.deviceType == DeviceType.mobile
  ? Container(   // Widget for Mobile
      width: 100.w,
      height: 20.5.h,
   )
  : Container(   // Widget for Tablet
      width: 100.w,
      height: 12.5.h,
   )

Suggestion

Orientation

If you want to give support for both portrait and landscape then make separate widget for both like orientation example.

DeviceType

If you want to give support for both mobile and tablet then make separate widget for both like deviceType example.

Note

You need to import appsize package in order to access number.h, number.w, and number.sp

Auto import in VSCode and Android Studio doesn't work for dart extension methods. Typing 10.h would not bring up auto import suggestion for this package

One workaround is to type Device so that the auto import suggestion would show up:

import 'package:appsize/appsize.dart';
