Question 1

How to export a funvas animation to a GIF?

Accepted Answer

Use the funvas_rendering package included in the repository, which provides tools to capture frames and compile them into GIF or video formats. Check the funvas_gallery package for example code on exporting animations, as mentioned in the README structure.

Question 2

funvas vs Flutter's built-in animation controllers: which is better for UI?

Accepted Answer

For standard UI animations like fading or sliding widgets, Flutter's built-in controllers are more suitable as they integrate with the widget tree. funvas is better for procedural, canvas-based visual art that doesn't rely on widget properties, as it focuses on low-level drawing.

Question 3

Can I use funvas for game development in Flutter?

Accepted Answer

While possible for simple 2D visual effects or artistic backgrounds, funvas is not a full game engine. For complex games, consider dedicated Flutter game packages like Flame, as funvas lacks features like collision detection or sprite management.

Question 4

What are some good math functions to start with in funvas?

Accepted Answer

Trigonometric functions like sine and cosine are commonly used for wave-like motions and periodic animations, as seen in the gallery examples. Start with these to create smooth, looping effects based on time parameters.

Question 5

Is funvas suitable for beginners in Flutter animation?

Accepted Answer

If you have a strong math background, it can be accessible due to its simple API, but for beginners to animation concepts, starting with Flutter's AnimationController might be easier before diving into procedural math-based animations.

Question 6

Does funvas support 3D animations?

Accepted Answer

No, funvas is primarily for 2D canvas animations, as it draws on a Flutter canvas which is 2D. For 3D effects, you'd need to simulate depth using mathematical projections or use other packages, as noted in the inspiration from processing.
