Draw and sync canvas in real-time | Create Flutter Figma Clone #2
The CustomPaint widget of Flutter is a flexible widget that allows us to paint any shapes and it is also performant allowing us to update its content rapidly. In this video, we will look at how we can use the CustomPaint widget of Flutter and combine it with the Supabase Realtime Broadcast feature to create a Figma clone application that updates the canvas in real time when editing it with multiple users.

Jump into part two of our Flutter Figma Clone series where we’re leveling up your app
development game and teaching you how to build and deploy a Figma clone app.
Building on the live cursor sharing introduced in part one (which you can view HERE), this video introduces drawing and manipulating shapes like circles and rectangles on a collaborative canvas. We’re showing you the best way to use Flutter's CustomPaint widget for its flexibility in drawing custom shapes and its performance in rapidly updating content so your designers don’t clash when it comes tp updates! Combined with Supabase's Realtime Broadcast feature, we achieve a seamless real-time update of the canvas, which basically mimics the best parts of Figma, namely the most collaborative, real-time updates that your team can see! No more accidental erasing of progress!
What you'll learn:
✅ Flutter's CustomPaint Widget: Explore using Flutter's CustomPaint widget for drawing shapes like circles and rectangles, and learn how to update the canvas content rapidly.
