import 'package:viam_sdk/viam_sdk.dart';

// Connect to an existing robot
// *NOTE* Get '<API KEY ID>' and '<API KEY>' from app.viam.com
final options = RobotClientOptions.withAPIKey('<API KEY ID>', '<API KEY>');
final robot = await RobotClient.atAddress('<LOCATION>', options);

// Print the available resources
print(robot.resourceNames);

// Access a component
final movementSensor = MovementSensor.fromRobot(robot, 'my_sensor');
print(await movementSensor.readings())
