flutter3d_backend 0.5.1

Picks the graphics backend a build draws through: Impeller on a desktop, WebGL2 in a browser, and a software rasteriser at runtime if Impeller will not start.

0.5.1

• The floors move to the 0.5.1 backends, and the reason is a coupling the version graph could not otherwise state. flutter3d 0.5.1 changed what the surface buffer's alpha means and added a member to the FogInfo uniform block, so an engine at 0.5.1 and a backend at 0.5.0 disagree about the shape of a block and about the units of a depth. Nothing forced them to move together: the engine names no backend — that is a structure rule — so this package is the only edge in the graph where the requirement can be written down, and it said ^0.5.0.
• What that mismatch actually does, since a floor is worth what it prevents: Impeller throws a StateError naming the block and the member, which is the failure this package's floor now makes unreachable; the software backend is quieter and merely goes on drawing the old picture, which is the case that wanted the floor most.
• One direction only. This package does not depend on flutter3d, so it cannot say "an engine at least as new as these backends". A project that pins the engine down while letting the backends float is still able to assemble a pair that disagrees.

0.5.0

• No API change. Its floors move to the 0.5.0 backends.

0.4.0

• No changes of its own; the version moves with the workspace, whose sibling constraints name a single release. The README's closing section now says what the engine around this package is.

0.3.0

• Picks the graphics backend a build draws through, with a conditional import rather than a runtime branch: the two pull in worlds that do not compile for each other's platform.
• openDevice was three files in each of three games and byte-identical in two of them.
• Deliberately does not decide resolution or shadow budget. Those are a game's trade against its own scene, and a shared constant would be wrong for two of the three.
