Question 1

How to load and display an image in GraphX?

Accepted Answer

Use ResourceLoader.loadImage() for assets or loadNetworkTexture() for URLs, then create a Bitmap object with the texture. Add it to the scene hierarchy using addChild() on a Sprite.

Question 2

GraphX vs Flutter's built-in CustomPainter for animations?

Accepted Answer

GraphX simplifies CustomPainter with a display list API for object management and input handling, but it adds overhead. For simple, one-off drawings, pure CustomPainter might be lighter.

Question 3

Can GraphX be used for 2D game development in Flutter?

Accepted Answer

Yes, with SceneConfig.games enabling auto-render, update cycles, and input support. It's suitable for lightweight games like the included Snake and Breakout demos.

Question 4

How to handle touch events on objects in GraphX?

Accepted Answer

DisplayObjects have signals like onMouseDown and onMouseUp. Listen to these in your Sprite subclasses to capture local coordinates and interact with scene elements.

Question 5

What are the performance tips for GraphX on mobile?

Accepted Answer

Optimize by using SimpleParticleSystem for particles, limiting deep display hierarchies, and leveraging SceneConfig.static for non-animated drawings to reduce ticker overhead.

Question 6

Is GraphX good for building custom data visualizations?

Accepted Answer

Yes, its imperative API and Shape graphics allow dynamic chart drawing, as shown in pie and line chart demos, but it requires manual implementation compared to dedicated chart libraries.
