Usage

Wrap your app with ```ResponsiveLayoutProvider```` to access screen size in the widget tree:

void main() {
  runApp(
    const ResponsiveLayoutProvider(
      child: MaterialApp(
        home: MyHomePage(),
      ),
    ),
  );
}

🧱 Core Widgets

✅ ResponsiveCenteredBody

Center your content and constrain its width (default maxWidth = 640).

ResponsiveCenteredBody(
maxWidth: 720,
backgroundColor: Colors.grey[200],
child: Text("Centered content"),
)

🔀 ResponsiveSplitBody

Automatically switches between vertical and horizontal layout:

ResponsiveSplitBody(
primaryChild: Text("Primary"),
secondaryChild: Text("Secondary"),
gap: 16,
)

Force layout direction:

ResponsiveSplitBody(
  forceVerticalLayout: true, // Always vertical
)

Custom breakpoints: use maxMobileWidth property of BreakPoints

 ResponsiveSplitBody(
breakPoints: BreakPoints(maxMobileWidth: 700),
)

📐 Context Extensions

• Use helpful extensions anywhere:

final screenWidth = context.width;
final screenHeight = context.height;

Global method for scalable sizes

    Column(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            Text(
              'text widget scaling with screen size',
              style: TextStyle(
                color: Colors.amber,
                // getRespSize will scale your given size according to screen size and TextSizes is class where you can some standarad 
                //text sizes
                fontSize: getRespSize(context, size: TextSizes.titleMedium),
                // TextScalingValues parameter to control of scaling 

              ),
            ),
            Icon(Icons.home, size: getRespSize(context, size: 22))
          ],
        ),
