The project will be a responsive Flutter application designed for tablets, which through an SSH connection and API calls, we will be able to represent the desired information on the LG. Additionally, the application will be autonomous, and without being connected to the LG, it will be able to represent and display information on the mobile device itself. The project will consist of two parts:
The first part is intended to represent past forest fires, to see all the affected areas, the development of the forest fire, and all the information represented on the Liquid Galaxy.
The second part will be to visualize real-time fires, whether they are forest fires or house fires, on the Liquid Galaxy and see their information.
In the third part of the project, what is dealt with is to represent the risks of forest fires in the United States area.
The Liquid Galaxy is a cluster of screens with Google Earth that synchronize with each other to create the sensation of a single screen, depending on the configuration it can be panoramic, vertical, curved, etc. Through this tool, we will be able to represent fires and see the impacts in an interactive and easy-to-see detail. Additionally, we will have many important data about the fire, such as the extent, emitted gases, possible victims, key points, extinguishing techniques, possible improvements, front speed, fire score, type of smoke column, smoke data, etc. All those data that we can extract from our API.
Before continuing, make sure to have installed in your machine Git and Flutter. Read Flutter documentation for further information.
Then, clone the project:
$ git clone https://github.com/LiquidGalaxyLAB/LG-Wildfire-tracker.git
$ cd LG-Wildfire-trackerWith the project cloned, run it by using the following command:
❗ You must have a mobile device connected or an android emulator running in order to run the app.
$ flutter run --no-sound-null-safetyThe
--no-sound-null-safetyflag is necessary due to thesshpackage.
In order to have a installed version of the app, you may download the APK in this repository or run the command below:
$ flutter build apk --no-sound-null-safetyThe
--no-sound-null-safetyflag is necessary due to thesshpackage.
Once done, the APK file may be found into the /build/app/outputs/flutter-apk/ directory, named app-release.apk.
With the app opened, a cog button (⚙️) may be seen into the home page toolbar (top right corner). When clicked, it will lead you to the settings page, in which a form may be found.
Fill it up with the Liquid Galaxy host name, password, IP address and SSH connection port (change it only if the system 22 default SSH port was changed).
After done, click into the Connect button and check whether there's a Connected green label above the form, in case it doesn't, there's something wrong with the given information or your device connection.
Once connected, head back to the home page and use the app as you wish. Note that all of the data is kept into the local storage after the first load. To update it with the database data, tap the SYNC button into the toolbar, next to the cog button (⚙️).
An important step to take is configure the slave screens for refreshing when setting solo KMLs.
To set it up, head to the settings page by hitting the cog button (⚙️) and go to the Liquid Galaxy tab.
In the button list, you shall see a button SET SLAVES REFRESH and RESET SLAVES REFRESH. The first one will setup your slave screens to refresh its solo KML every 2 seconds. The second one will make your slaves stop refreshing.
❗ Both actions will reboot your Liquid Galaxy, so the changes may be applied.
