web library

Configuration the browser build needs, and nothing the other platforms do.

The browser build's four files ship inside this package, and dart run wxscan:fetch_web copies them into web/wxscan, where the package looks by default. They are files rather than declared assets because declaring Flutter assets would make this a Flutter package, which would cost dart run and dart test. This says where they are when they are somewhere else.

// Before creating a scanner, and only on the web.
configureWxScanWeb(const WxScanWebPaths(
  workerUrl: 'assets/wxscan/wxscan_worker.js',
  wasmUrl: 'assets/wxscan/wxscan_wasm.wasm',
  tfliteUrl: './wxscan_tflite.js',
));

Of the four, wxscan_worker.js is this package's own; the rest are compiled elsewhere — wxscan_wasm.wasm by crates/wxscan-wasm in wxscan-rs, and the wxscan_tflite.js and wxscan_tflite.wasm pair by wxscan-litert-wasm. Only the loader of that pair takes a URL, since it fetches the module beside itself, and the two must keep their names: the loader has its module's file name compiled into it.
