C interoperability with Dart FFI
summary
Shows how to call C from Dart by following the three explicit steps: open the dynamic library, look up the symbol, call it, and handle C memory. Demonstrates automatic binding generation with FFI GEN, wraps the generated C API for SQLite in an idiomatic database class, and wires that to a Flutter Veggies app search page so queries run against a real SQLite DB and the search works.
