Use `drawAtlas` for Particles #2221

Open spydon opened 1 year ago

spydon commented 1 year ago

What could be improved

We should investigate whether drawAtlas can now be used for particles.

Why should this be improved

It should be insanely much more efficient.

Any risks?

That it might not work properly on all platforms: https://github.com/flutter/flutter/issues/88220

I believe https://github.com/flutter/flutter/issues/88220 shouldn't affect your use-case. That issue seems to be caused by our lack of targetWidth and targetHeight support in image Codec. However, particles can be created from pictures at desired resolution like this, i.e. there's nothing to decode.
