(In)stability Notice

Warning This is a beta release of the Viam Flutter SDK. No guarantees are made to the stability of the API. All changes will be enumerated in the release notes.

Getting started

Make sure your project meets the minimum requirements:

• Minimum iOS target: 13.0
• Minimum Android SDK: 23
• Kotlin version: 1.8.20

Installation

flutter pub add viam_sdk

Upgrading

flutter pub upgrade viam_sdk

Note that breaking changes may occur in patch version changes because the Viam Flutter SDK is still in beta. We recommend locking your project to a specific version by adding a specific version number (for example viam_sdk: 0.0.12) to your pubspec.yaml file.

Update Info.plist

If you are building for Apple platforms, you may have to update your app's Info.plist. NSLocalNetworkUsageDescription is needed to establish stable WebRTC connections, and NSBonjourServices is required to connect to local devices via mDNS.

<key>NSLocalNetworkUsageDescription</key>
<string>Viam requires access to your devices local network to connect to your devices.</string>
<key>NSBonjourServices</key>
<array>
    <string>_rpc._tcp</string>
</array>

Usage

You can use the Viam SDK to connect to an existing machine (to create a machine, see Build a simple smart machine or if you don't have your own hardware, Try Viam).

import 'package:viam_sdk/viam_sdk.dart';

// Connect to an existing machine (robot)
// *NOTE* Get '<API KEY ID>' and '<API KEY>' from
// your machine's "CONNECT" tab on 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())
