minigpu_web 1.7.0

A web library for minigpu wasm. A library that brings multiplatform GPU compute to Dart and Flutter using WebGPU and Google Dawn.

minigpu_web CHANGELOG

1.7.0

• writeRawBytes no longer allocates and fills a whole second list per call. It built a fresh Uint32List the size of the payload and memcpy'd into it on every call, only to reinterpret the same bytes as words. On a streaming path that is a whole-frame allocation plus a whole-frame copy per frame — 33 MB at 4K — and the allocation is per-frame garbage large enough to be a frame-time spike source in its own right, not just a copy. It now takes a 4-byte-aligned VIEW over the caller's bytes, which aliases the same store and costs nothing. The copy remains only for the one case a view cannot describe (a caller-supplied view whose offsetInBytes is not 4-aligned). This is the web half of the same bug fixed natively in minigpu_ffi, and it matters more here: the browser has no equivalent of the native path's escape hatches.

1.6.1

• released 08/13/26 - MR

1.6.0

• Version bump to keep the minigpu 1.6.0 family aligned. No functional change in this package (the fix is native-only and does not apply to the web build).

1.5.9

• Version lockstep with minigpu 1.5.9; no behavior change. setBufferFire aliases setBuffer on web, which stays correct now that the facade always binds through it — single-threaded wasm executes GPU tasks in call order.

1.5.8

• Implement the new platform-interface members on web: setBufferFire aliases setBuffer (single-threaded wasm runs GPU tasks in call order, so the plain bind already has FIFO semantics); dispatchFire drops the returned promise (queue.submit is synchronous in JS WebGPU — the promise only covers call plumbing, so submission order holds); writeRawBytes writes at offset 0 via the u32 path and throws UnsupportedError otherwise.
• listAdapters / createSecondaryPlatform / drainSpinBudgetMs inherit the interface's no-op defaults — no multi-adapter contexts on web, and the native drain fix does not apply.

1.5.7

• Version lockstep with minigpu 1.5.7; no behavior change.

1.5.6

• Version lockstep with minigpu 1.5.6 (new preferDisplayAdapter / selectedAdapterName platform members inherit the interface's no-op defaults on web — no behavior change).

1.5.5

1.5.4

• fix release version pins

1.5.2

• fixing build hook

1.4.9

• tryfix central dawn location

1.4.8

• fixes texture path on windows, fixes texture view on web

1.4.7

• Fixes logger characters

1.4.6

• fix garbled adapter name in logs: WGPUStringView.data is not null-terminated, copy to std::string before passing to snprintf
• fix garbled adapter name in logs: WGPUStringView.data is not null-terminated, copy to std::string before passing to snprintf

1.4.5

• fix Dawn built inside pub-cache instead of system dir: pass DAWN_DIR from Dart hook as cmake -D define so cmake subprocess inherits the correct path regardless of env; fix FETCHCONTENT_BASE_DIR pointing to pub-cache (now uses cmake binary dir)
• add Minigpu.setLogCallback / setLogLevel: routes native Dawn/GPU log lines through a Dart callback (NativeCallable.listener); mgpuSetLogCallback + mgpuSetLogLevel exported from C layer; all stderr calls in minigpu_external.cpp replaced with structured LOG_ERROR/INFO/WARN/DEBUG macros

1.4.4

• fix FormatException on non-UTF-8 bytes in setLogCallback: use Utf8Decoder(allowMalformed: true) instead of toDartString()

1.4.3
