In this tutorial, we are going to learn how to fetch data from a Spring Boot REST service and display the results in Flutter UI.

For this purpose, we are going to build an application that collects server data about the status of some required services.

Imagine that you have multiple servers where some services are required to be running. Instead of manually connecting via SSH to the servers and executing service check commands, we are going to create a service checker application that displays all the data for us.

Let’s get started!

Prepare the Back End

First, let’s create a very basic Spring Boot project. I am using Gradle as a build tool in this tutorial. We only need to get the org.springframework.boot:spring-boot-starter-web dependency:

If you need more information on how to get started with Spring Boot, refer to the documentation.

1. Create the application starter

package com.serverchecker;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Api {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        SpringApplication.run(Api.class, args);
    }
}
