Responsive Widgets and Screen Utilities

The need for responsiveness

Modern applications aren’t limited to just one type of screen. We use apps on our computers, phones, and even wearable devices. This becomes even more evident when we talk about Flutter, the framework that lets us deploy apps to any platform.

One widget, multiple layouts

GetResponsiveView is a widget that lets us build different layouts for different screen sizes, all in one class. Screen sizes are categorized by the relevant device names and each one has a corresponding method. We can return a different layout in each of these methods, and when the app window is resized, or the app is opened on a device of a different screen size, the relevant layout is rendered automatically. For example, we can have a detailed UI for the desktop app, and a minimal one for the mobile app.
