minigpu_web 1.9.1

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

1.9.1

• The bundled minigpu_web.wasm is now an optimized release build, about 0.56 MB instead of 13.1 MB. It no longer carries debug info, so browser stack traces inside it show function numbers instead of names.

1.9.0

• Reads put the data at the start of the output list; it used to land at the element offset.

• Reads and writes take any typed list as bytes, including 64-bit lists and ByteData, which used to be dropped or ignored.

• A count past the input, the output or the GPU buffer throws RangeError.

• Overlapping reads and context calls now run one at a time, and a destroy waits for them. Before, they could hang or corrupt memory.

• writeRawBytes uploads straight from the caller's bytes at every offset.

• A failed module load is retried, and a page loads the loader script once.

• setLogCallback defaults to warnings and errors, like native.

• A read that fails throws StateError instead of returning stale data.

• Render pipelines implement settled: the module reports when a pipeline finishes compiling, so preparing one no longer polls.

• Compute shaders implement buildPipeline(), which compiles without dispatching.

• toRGBAAsync throws UnsupportedError, like toRGBA.

• A buffer bound without a binding kind takes the access its kernel declares, as on native.

• The bundled wasm module is rebuilt, so it carries the native fixes listed for minigpu_ffi, with no fast-math and a 1 MB Asyncify stack instead of 64 MB.

• Retire GPU-only resources after the exact creation device's observed WebGPU loss. Keep host-reader teardown separate and reject healthy, stale or merely unavailable device lookups.

• Add final module-retirement observation and root-owned browser recovery. Replacement preserves required features/limits on a fresh browser-selected device; it does not claim native physical-adapter identity. Rejected candidates must retire before explicit Retry. Outstanding readers still block replacement.

1.8.1

• Implement webBufferHandle on WebBuffer (via mgpuGetWGPUBufferHandle), exposing the WebGPU buffer handle for zero-copy presentation on the same device.

1.7.0

• writeRawBytes no longer allocates and copies a second list per call. It now uses a 4-byte-aligned view of the caller's bytes. At 4K the old copy was a 33 MB allocation per frame, and the garbage it left could cause frame-time spikes. A copy is still made when the caller's view does not start on a 4-byte boundary.

1.6.1

• released 08/13/26 - MR

1.6.0

• Version bump for the minigpu 1.6.0 family. No functional change (that fix is native-only).

1.5.9

• Version lockstep with minigpu 1.5.9; no behaviour change. setBufferFire is an alias for setBuffer on web, which is correct because the browser runs GPU work in call order.

1.5.8

• Implements the new platform-interface members. setBufferFire aliases setBuffer and dispatchFire does not wait for the dispatch; on web both already run in call order. writeRawBytes works at offset 0 and throws UnsupportedError for any other offset.
• listAdapters, createSecondaryPlatform and drainSpinBudgetMs keep the interface's defaults: there are no multi-adapter contexts on web, and the native GPU-wait fix does not apply.

1.5.7

• Version lockstep with minigpu 1.5.7; no behaviour change.

1.5.6

• Version lockstep with minigpu 1.5.6. The new preferDisplayAdapter / selectedAdapterName members keep the interface's no-op defaults on web.

1.5.5

1.5.4
