flutter_capture_vision_linux

Linux implementation of flutter_capture_vision.

Endorsed default_package for the facade — you normally depend only on flutter_capture_vision and get this package automatically.

Implementation notes

  • C++ plugin over the DCV desktop SDK (CCaptureVisionRouter), with x64 and arm64 libraries plus the full resource set (Templates, Models, ParserResources, root .data files) vendored into this package.
  • All channel operations run on a dedicated serial worker thread; replies are posted back through the main GLib context.
  • CMake selects the library matching the target architecture, installs everything under the bundle's lib/ with $ORIGIN rpath, and installs the resource directories next to the executable. After flutter build linux, verify with ldd that bundled libraries resolve from the bundle.
  • Default task → template mapping: barcode → ReadBarcodes_Default, mrz → ReadPassportAndId, documentDetection → DetectDocumentBoundaries_Default. Custom names from imported settings JSON are passed through unchanged.
  • This package carries both architectures; if pub archive size ever exceeds the pub.flutter-io.cn limit, split per-architecture rather than downloading resources at runtime (see docs/release-runbook.md in the workspace).

See example/ for a minimal app exercising this implementation.
