Flutter Hue #

Flutter Hue logo

An SDK designed for the Flutter framework that enables developers to easily integrate Philips Hue smart devices into their applications.

Note: This SDK uses Philips Hue's new API v2.

With Flutter Hue, developers can easily discover Hue bridges on the network, establish communication with them, and manipulate their connected devices. All of this is shown in the examples below. Also shown is how to change the color of lights and turning them on and off.

Features #

Shown in this demo gif:

  1. Discover bridges on the network
  2. Establish connection with the bridges
  3. Discover the devices that are connected to the bridges
  4. Identify a light (used to let the user know what light they are configuring)
  5. Toggle a light on and off
  6. Change the color of a light

A gif demonstrating Flutter Hue in action.

Installation #

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  flutter_hue: ^2.0.0-beta.3

Import it to each file you use it in:

import 'package:flutter_hue/flutter_hue.dart';

Usage #

Establishing Remote Connection #

Without doing this, your app will only be able to communicate with Philips Hue bridges that are on the same network as the user's device. This section will show you how to establish a remote connection with a bridge; that way, it can be controlled from anywhere in the world.

Due to the length of these instructions, they have been placed in their own document, here.

Once you have completed the steps in the above document, you will be able to communicate with a bridge remotely using the same steps as all of the examples below.

It is not necessary, but it is highly recommended that you add this code snippet to the root of your app. It will keep the locally stored data (bridges, tokens, etc.) up to date.

FlutterHueMaintenanceRepo.maintain(
  clientId: "[clientId]",
  clientSecret: "[clientSecret]",
  redirectUri: "flutterhue://auth",
);

Note: If your app does not support remote connection, just use FlutterHueMaintenanceRepo.maintainBridges to maintain your local data.

Example 1 - Get bridge IPs #

This example shows how to get a list of all of the IP addresses of the Philips Hue bridges on the network.

List<String> bridgeIps = await BridgeDiscoveryRepo.discoverBridges();

Example 2 - First contact with bridge #

This example shows how to establish first contact with a bridge on a device. This is what causes the bridge to create an application key for the user's device.

Warning: Any device with this key will have access to the bridge. It is meant to be kept secret.

Bridge myBridge = await BridgeDiscoveryRepo.firstContact(
  bridgeIpAddr: 192.168.1.1, // Get IP in example 1
  controller: timeoutController,
);

Example 3 - Find all devices on Hue Network #

This example shows how to find every Philips Hue device on the network.

Note: This is only for devices that are connected to a bridge that the user's device has access to (see example 2).

// Create the network object
// Get the bridges in example 2
HueNetwork myHueNetwork = HueNetwork(bridges: [bridge1, bridge2]);

// Populate the network object
await hueNetwork.fetchAll();

Example 4 - Change light color #

This example shows how to change the color of a light.

// Get a light to change the color of.
// Hue Network can be found in example 3
Light myLight = myHueNetwork.lights.first;

// Set a new color that you want to change the light to
myLight = myLight
  .copyWith(
    color: myLight.color.copyWith(
      xy: LightColorXy(x: 0.6718, y: 0.3184),
    ),
  );

// Send the PUT request to change the color of the light.
await bridge.put(myLight);

Example 5 - Toggle light on/off #

This example shows how to turn multiple lights on and off.

// Get the grouped light from the room
GroupedLight myGroupedLight = myHueNetwork.rooms.first.servicesAsResources
    .firstWhere((resource) => resource is GroupedLight) as GroupedLight;

// Toggle the on/off state
myGroupedLight.on.isOn = !myGroupedLight.on.isOn;

// PUT the new state
myHueNetwork.put();

Example 6 - Color converters #

This example shows how to use the color converters.

ColorConverter.xy2rgb(0.5, 0.5); // [255, 222, 0]
ColorConverter.rgb2hsl(255, 0, 0); // [0.0, 1.0, 0.5]
ColorConverter.hsv2hex(0, 1.0 , 1.0); // "ffff0000"
ColorConverter.color2hsv(Color(0xffff0000)); // [0.0, 1.0, 1.0]
ColorConverter.int2rgb(4286611584); // [128, 128, 128]

// Also can be used as an extension of Flutter's `Color` object
Color myColor = Color(0xff8a4888);

myColor.toXy(); // [0.3209554122773742, 0.21993715851681886, 0.1181557673818057]
myColor.toRgb(); // [138, 72, 136]
myColor.toHex(); // "ff8a4888"
myColor.toInt(); // 4287252616

Example 7 - Hue icons #

This example shows how to use Philips Hue's icons.

Icon(HueIcon.classicBulb);

IconButton(
    onPressed: () {},
    icon: Icon(HueIcon.stringLight),
);

Example 8 - Entertainment Streaming #

This example shows how to use Entertainment Streaming. It's important to note, you will need to use the official Philips Hue app to create entertainment areas before you can use Flutter Hue to interact with them. At the time of writing this, Philips does not give third party apps the ability to create entertainment areas.

// Get one of your stream areas that you made in the official Hue app.
EntertainmentConfiguration myEntertainmentStreamConfiguration =
    myHueNetwork.entertainmentConfigurations.first;

// Start the stream.
myEntertainmentStreamConfiguration.startStreaming(myBridge);

// These are the colors that are used by the stream commands.
final ColorXy red = ColorXy.fromRgb(255, 0, 0, 1.0);
final ColorXy blue = ColorXy.fromRgb(0, 0, 255, 1.0);

// The amount of time the light will remain on each color before switching to
// the next.
const int waitDurationMillis = 500;

final EntertainmentStreamCommand command1 = EntertainmentStreamCommand(
  channel: 0,
  color: red,
  waitAfterAnimation: const Duration(milliseconds: waitDurationMillis),
);

final EntertainmentStreamCommand command2 = EntertainmentStreamCommand(
  channel: 0,
  color: blue,
  waitAfterAnimation: const Duration(milliseconds: waitDurationMillis),
);

// Infinity loop the stream commands. This toggles the light between red and
// blue forever.
while (true) {
  // IMPORTANT NOTE: The copy method is used here to ensure that the same
  // command isn't added to the queue multiple times. If the same command is
  // added multiple times, the bridge will only execute the command once.
  myEntertainmentStreamConfiguration.addAllToStreamQueue(
    [command1.copy(), command2.copy()],
  );

  // Wait before adding the next set of instructions to the loop. This is not
  // required, but it is encouraged to improve efficiency.
  await Future.delayed(const Duration(milliseconds: waitDurationMillis * 2));
}
