Introduction

The goal of this tutorial is to demonstrate the basic setup of ThingsBoard Mobile Application with your ThingsBoard platform instance. You will learn how to:

• Setup development environment;
• Get application project source code;
• Configure API endpoint to your ThingsBoard platform instance;
• Build and run your version of ThingsBoard Mobile Application;

Step 1. Prepare development environment

Flutter ThingsBoard Mobile Application requires Flutter SDK starting from version 2.12.0. Follow these instructions in order to setup Flutter SDK. For an even better experience we recommend to set up an editor using these instructions.

Flutter ThingsBoard Mobile Application is served by ThingsBoard platform starting from version 3.4.0. You will need to have ThingsBoard server up and running. The easiest way is to use Live Demo. The alternative option is to install ThingsBoard using Installation Guide.

Step 2. Get app source code

Flutter ThingsBoard Mobile Application compatibility table

Determine the Flutter ThingsBoard Mobile Application version according to the version of ThingsBoard.

You can get Flutter ThingsBoard Mobile Application source code by cloning it from github repository:

1
git clone -b release/1.1.0 https://github.com/thingsboard/flutter_thingsboard_app.git

Step 3. Configure ThingsBoard API endpoint

Open flutter_thingsboard_app project in your editor/IDE. Edit lib/constants/app_constants.dart.

Set value of thingsBoardApiEndpoint constant to match api endpoint of your ThingsBoard server instance.
In case of Live Demo set it to https://demo.thingsboard.io.

6
abstract class ThingsboardAppConstants {
  static final thingsBoardApiEndpoint = 'https://demo.thingsboard.io';
  
  ...
}

Note: Do not use localhost or 127.0.0.1 host names.
If you are using local ThingsBoard installation use alternative ip address/host name accessible within your local network.
You can read Connecting Flutter application to Localhost for more information.

Step 4. [Optional] Configure push notifications

Our system leverages Firebase to send notifications from ThingsBoard instance directly to mobile application. This setup requires each platform tenant to configure Firebase specifically for their account to begin the distribution of notifications to their mobile app.

Step 4.1 Create Firebase project

Next, we will walk through step-by-step how to create a Firebase project, and within it, we will generate a private key. This key is required for securely connecting your ThingsBoard instance to Firebase services.

Please note: for ThingsBoard CE, only the system administrator can configure mobile settings. For ThingsBoard PE - the tenant can use the system administrator’s configuration or specify their own.

So let’s get started:

• Sign in to your Firebase account. Once you're in, click the “Create a project” button;

• Enter your desired project name in the field provided, then click “Continue”;

• Next up is deciding on Google Analytics for your project. You have the option to keep it enabled or disable it if you prefer not to use it. Once you've made your choice, click “Continue”;

• After setting up Google Analytics, confirm your project creation by clicking the “Create project” button;

• Your Firebase project is now ready. Click “Continue” to open the Firebase project control panel;

• In the menu on the left, go to “Project Overview” -> “Project settings” page;

• In the “Project settings” page, switch over to the “Cloud Messaging” tab. Here, ensure the Firebase Cloud Messaging API is enabled to use messaging features;

• Head over to the “Service accounts” tab next. Within the “Admin SDK configuration snippet”, select the “Java” section. Then, click on the “Generate new private key” button. This action will generate a private key for your service account - crucial for secure server communication;

• Confirm the generation of your private key by clicking on the “Generate key” button. Keep this key safe, as you'll need it for the ThingsBoard server-side operations;

• Sign in to ThingsBoard as a system administrator, open the “Settings” page and navigate to the “Notifications” tab. In the “Mobile settings” section, upload the private key file you generated in the Firebase project and click “Save” to finalize the configuration.

Step 4.2 Add Firebase to your mobile application

To integrate Firebase into the mobile application, you’ll need to complete the initial two steps outlined in the “Add Firebase to your Flutter app” guide available at Firebase’s official documentation.

[Only for IOS] Apple app configuration

Upload APNs authentication key to Firebase.

• First, create APNs authentication key in the Apple Developer Member Center using Apple’s official documentation;
• Inside your Firebase project, go to the “Cloud Messaging” tab of the “Project Settings” page. Scroll down and found “Apple app configuration” section;
• In “APNs authentication key” click the “Upload” button;
• Add APNs authentication key and enter “Key ID” and “Team ID” in the corresponding fields;
• Then click “Upload” button.

The APNs authentication key is uploaded.

Step 4.3 Check project configuration

After successfully completing these steps, make sure that your project contains the following file:

• If your ThingsBoard mobile application is intended for iOS:

1
ios/Runner/GoogleService-Info.plist

• If your ThingsBoard mobile application is intended for Android:

1
android/app/google-services.json

Please note: if the flutter_thingsboard_app project is currently running, please stop it and proceed with a rebuild.

To confirm that Firebase has been integrated properly, run your application (Step 5). If everything is configured correctly, the notifications menu in your mobile application should be active, as shown in the screenshot below.

Learn more about notifications and how to configure them here.

Step 5. Run the app

Run the app in the way your IDE describes.

When using terminal run the app with the following command:

1
flutter run

You should see either Android or iOS output, depending on your device.

Android

iOS

Tip: The first time you run on a physical device, it can take a while to load. Afterward, you can use hot reload for quick updates.

Save also performs a hot reload if the app is running. When running an app directly from the console using flutter run, enter r to perform hot reload.

Step 6. [Optional] Build and release mobile application

If you need to build and release ThingsBoard Mobile Application for iOS or Android, please refer to this guide.

Live demo app
