engineRunJson static method
Runs a synchronous inference. Returns the JSON response as a Dart
string, or null on failure. The native string buffer is freed
internally — callers do not need to call stringFree.
Implementation
static String? engineRunJson(
SyniEngineNative engine,
SyniPreset preset,
int seed,
String requestJson,
) {
initialize();
final jsonPtr = requestJson.toNativeUtf8();
try {
final resultPtr = _engineRunJson!(engine, preset.value, seed, jsonPtr);
if (resultPtr == nullptr) return null;
final result = resultPtr.cast<Utf8>().toDartString();
_stringFree!(resultPtr);
return result;
} finally {
malloc.free(jsonPtr);
}
}
