How to write a Flutter app that is usable and beautiful across platforms.To accomplish this, this codelab uses tools and APIs introduced in Material 3. In this codelab, you enhance a Flutter music application, taking it from boring to beautiful. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source. We can drag our Draggable Boxes onto this DragTarget widget to change it's color to the color of the Draggable Box.Flutter is Google's UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. We then create a static UI element that makes use of the DragTarget Class. The Offset determines where the box is at a given moment with it having an initial state and a state that gets updated based on where the user drags the box. We then are able to embed multiple boxes into this skeleton, each one with an Offset, a Color and a Label string.

We also look at how we can position widgets on our screen using the Stack Layout Widget.įirst we build out our skeleton application. The basic concept is to be able to drag a box from one part of a screen to another and be able to transfer the color state of the box to a fixed widget on the screen called a DragTarget. In this video Tutorial, We look at how we can build out a drag and drop based widget inside of the Flutter Framework.
