ResponsiveX

A simple Flutter package to handle responsiveness.

Overview

The package consists of the followings:

• SizeConfig - is the simple class that makes calculation for responsiveness.
• Extensions - are functions to calculation dynamic height, width and font size.

Example

First of all, you should initialize SizeConfig class using it's init method and giving the your design sizes (Height and Width given by your designer as screen size):

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return LayoutBuilder(
      builder: (context, constraints) {
        return OrientationBuilder(
          builder: (context, orientation) {
            SizeConfig(
              designScreenWidth: 360,
              designScreenHeight: 640,
            ).init(constraints, orientation);

            return MaterialApp(
              title: 'Flutter Demo',
              theme: ThemeData(
                primarySwatch: Colors.blue,
                visualDensity: VisualDensity.adaptivePlatformDensity,
              ),
              home: MyHomePage(title: 'Flutter Demo Home Page'),
            );
          },
        );
      },
    );
  }
}

Then you can use extension methods to calculate height, width and font size dynamically:

          Container(
            height: context.computeHeight(100),
            width: context.computeWidth(100),
            color: Colors.pink,
          ),

You can calculate font size as following:

          Container(
              height: context.computeHeight(100),
              width: context.computeWidth(100),
              color: Colors.pink,
              child: Center(
                child: Text(
                  'ResponsiveX',
                  style: TextStyle(
                    fontSize: context.computeFontSize(14),
                    color: Colors.white,
                  ),
                ),
              ),
            ),
