responsive_framework 0.0.1

A new Flutter package project.

Responsive Framework

Write Once, Responsive Everywhere!

Responsive Framework adapts your UI to different screen sizes automatically. Create your UI once and have it display correctly on mobile, tablet, and desktop!

The Problem

Supporting multiple display sizes often means recreating the same layout multiple times with the traditional Bootstrap approach. This is time consuming, frustrating and repetitive work. Furthermore, getting your designs pixel perfect is near impossible and editing becomes a nightmare.

The Solution

Use Responsive Framework to automatically resize or scale your UI based on breakpoints.

ResponsiveWrapper(
    child,
    breakpoints: [
        ResponsiveBreakpoint(breakpoint: 600, name: MOBILE),
        ResponsiveBreakpoint(breakpoint: 800, name: TABLET),
        ResponsiveBreakpoint(breakpoint: 1200, name: DESKTOP),
    ],
)

Resize vs Scale

To easily adapt to a wide variety of screen sizes, set breakpoints to proportionally scale or resize a layout.

ResponsiveBreakpoint(breakpoint: 600, scale: true)

This eliminates the need to manually adapt layouts to mobile, tablet, and desktop.

To understand the difference between resizing and scaling, take the following example. An AppBar widget looks correct on a phone. When viewed on a desktop however, the AppBar is too short and the title looks too small. This is because Flutter does not scale widgets by default. Here is what happens with each behavior:

1. Resizing (default) - the AppBar's width is double.infinity so it stretches to fill the available width. The Toolbar height is fixed and stays 56dp.
2. Scaling - the AppBar's width stretches to fill the available width. The height scales proportionally using an aspect ratio automatically calculated from the nearest ResponsiveBreakpoint. As the width increases, the height increases proportionally.

Setting Breakpoints

An arbitrary number of breakpoints can be set. Resizing/scaling behavior can be mixed and matched as below.

• 1400+: scale on extra large 4K displays so text is still legible and widgets are not spaced too far apart.
• 1400-800: resize on desktops to use available space.
• 800-600: scale on tablets to avoid elements appearing too small.
• 600-350: resize on phones for native widget sizes.
• below 350: resize on small screens to avoid cramp and overflow errors.\
