dart_pdf_editor_flutter_gpu 0.1.5

Opt-in Impeller flutter_gpu tile backend for dart_pdf_editor.

Changelog

0.1.5

• Align the experimental Flutter GPU backend with the 3.7.0 package suite.

0.1.4

• Isolate pipelines, geometry buffers, and image textures by Flutter GPU context so native windows never reuse resources owned by another view.
• Keep image-texture leases alive until in-flight command buffers complete, preventing stale blocks or unrelated fragments after structural edits.
• Report context identities and switches in the backend diagnostics.

0.1.3

• Rebuild the packaged shader bundle with Flutter 3.47's impellerc so the runtime accepts the new bundle format.

0.1.2

• Support both the Flutter 3.44 and 3.47 flutter_gpu APIs after shader loading became asynchronous and draw vertex counts moved to draw.

0.1.1

• Fall back to the Canvas renderer for deferred image soft masks that the GPU backend cannot yet reproduce exactly, preserving correct output on Impeller.

0.1.0

• Render final GPU tile textures directly and admit one per repaint, avoiding deferred slab-to-tile texture-copy bursts. Track synchronous issue time and command-buffer completion latency, failures, and in-flight submissions.
• Render ordinary non-rectangular PDF clip stacks exactly with retained stencil geometry, including nested even-odd/nonzero clips and save/restore; rectangular clips keep the cheaper scissor path.
• Report compiled clip paths and per-tile clip-mask rebuilds in backend stats.
• Add an opt-in Impeller flutter_gpu backend for retained-scene LoD tiles.
• Retain geometry and byte-budgeted image textures across tile renders and combine supported image soft masks directly in the tile shader.
• Pack command-heavy CAD geometry into backend-wide reusable 16 MiB device buffers under a strict byte budget, releasing leases only after GPU work completes and falling back instead of overshooting the ceiling.
• Fall back to the Canvas backend for unsupported pages and expose a web stub that preserves the same host API.
• Expose JSON-safe diagnostics for the latest tile route, accepted/rejected/ active sessions, runtime fallbacks, compile/replay timings, cache pressure, uploads/readbacks, and live GPU resource leases.
