Static Methods

autoRegister() → void
dispose() → void
isArchitectureSupported(HexagonArch arch) bool
Whether arch is in QHexRT's native device-validated support set. No architecture set is duplicated in Dart.
modelRequiresHfAuth(String modelId) bool
Whether QHexRT's native product policy marks modelId HF-authenticated.
modelSupportsArchitecture(String modelId, HexagonArch arch) bool
Match QHexRT's native product policy for modelId against arch.
probeNpu() NpuCapability
Probe the Hexagon NPU without loading QNN. Safe on any device.
register() Future<bool>
Register the QHexRT backend with the C++ plugin registry. Safe to call multiple times; on unsupported devices registration is rejected.
registerModelForDevice({required RegisterModelFromUrlRequest request}) Future<ModelInfo?>
Register request only when native product policy allows it on this device. URLs and presentation metadata stay in the app; QHexRT owns probing/selection and composes commons' shared model registration and download pipeline. A null value is a normal ineligible model/device outcome.
unregister() Future<void>
Unregister the QHexRT backend. Async for symmetry with register.
