Meta Wearables Device Access Toolkit; isolate native SDK code behind a Flutter platform interface; stream camera, audio, motion and device state without rebuilding the whole screen. flutter create robotics_performance_app cd robotics_performance_app flutter run abstract class RobotGateway { Stream<Map<String, dynamic>> telemetry(); Future<void> sendCommand(Map<String, dynamic> command); } Keep Meta, Google/XR, Jetson and ROS-specific code behind this boundary. StreamBuilder<Map<String, dynamic>>( stream: gateway.telemetry(), builder: (_, snapshot) { return Text('${snapshot.data?['status'] ?? 'Offline'}'); }, ) Do not rebuild an entire dashboard when only one metric changes. Map<String, dynamic>? latest; void onTelemetry(Map<String, dynamic> value) { latest = value; } For high-rate camera/sensor streams, prefer the newest useful value rather than an unlimited backlog. final result = await Isolate.run(() { return expensivePreprocessing(); }); Use isolates when Dart CPU work is substantial; native accelerated processing may be more appropriate for camera/AI SDK workloads. Measure: capture → transport → preprocessing → inference → UI Use Flutter DevTools Performance View and test in profile mode. For robots, Android/Flutter must not be the only safety layer. The robot/ROS 2 side should have connection monitoring and a watchdog that moves the robot to a safe state when control messages stop. Avoid expensive work in build(). Use const widgets where practical. Split frequently changing widgets. Use lazy lists for large collections. Sample high-frequency telemetry. Avoid unnecessary image copies. Measure frame build/render time. Measure end-to-end latency. Test on the lowest target hardware. Keep actuator safety deterministic and robot-side. Flutter works well as the cross-platform UI, visualization and operator layer, while native wearable APIs, NVIDIA Jetson, ROS 2 and accelerated AI runtimes handle hardware-specific workloads.
