defaultFlutterGemmaInstance function
Default FlutterGemmaPlugin for platforms with dart:io (mobile + desktop).
Selected via conditional import from flutter_gemma_interface.dart. Keeping
the FlutterGemmaMobile reference behind this file is what keeps dart:io
off the web/wasm import graph (see flutter_gemma_default_web.dart).
Implementation
FlutterGemmaPlugin defaultFlutterGemmaInstance() => FlutterGemmaMobile();
