ResponsiveLayout class

A widget that provides a responsive layout based on the screen size. It displays different widgets for mobile, tablet, and desktop sizes. The mobile layout is used for screens smaller than 650 pixels, the tablet layout is used for screens between 650 and 1100 pixels, and the desktop layout is used for screens larger than 1100 pixels. The tablet layout is optional and defaults to the desktop layout if not provided. The ResponsiveLayout widget is useful for creating applications that need to adapt to different screen sizes and orientations. It uses the MediaQuery class to determine the screen size and display the appropriate layout. The ResponsiveLayout widget takes three required parameters:

• mobile: The widget to display for mobile screens.
• tablet: The widget to display for tablet screens (optional).
• desktop: The widget to display for desktop screens. The ResponsiveLayout widget also provides three static methods to check the current screen size:
• isMobile: Returns true if the screen size is less than 650 pixels.
• isTablet: Returns true if the screen size is between 650 and 1100 pixels.
• isDesktop: Returns true if the screen size is greater than 1100 pixels. These methods can be used to conditionally render widgets based on the screen size.

Example usage:

ResponsiveLayout(
 mobile: mobileWidget(),
 tablet: tabletWidget(),
 desktop: desktopWidget(),
 );
