FlutterFlow and Microsoft SQL Server integration: Step-by-Step Guide 2024

Learn how to seamlessly integrate FlutterFlow with Microsoft SQL Server through this step-by-step guide. Simplify your development process with our easy instructions.

What is Microsoft SQL Server?

Microsoft SQL Server is a relational database management system developed by Microsoft. It is used for managing and storing information in businesses. The server supports various data types, from small applications to large internet-facing applications. Besides data storage, it provides tools for data integration, reporting and analysis. SQL Server operates in various editions, each accommodating different functionalities and workloads, such as Enterprise, Standard, and Express.

How to integrate FlutterFlow with Microsoft SQL Server?

 

Step-by-Step Guide on Integrating FlutterFlow with Microsoft SQL Server

  Prerequisites
  • FlutterFlow Account: You need an account on FlutterFlow to create and manage your projects.
  • Microsoft SQL Server: Ensure you have access to a Microsoft SQL Server instance. This could be a local server, a cloud-based server, or an instance hosted by a third-party provider.
  • Basic Knowledge: Awareness of basic concepts in SQL, REST APIs, and FlutterFlow.
 

Step 1: Set Up Your Microsoft SQL Server

  1. Install Microsoft SQL Server: If you don't have Microsoft SQL Server installed, download and install it from the official Microsoft SQL Server website. 2. Create a Database: Use SQL Server Management Studio (SSMS) or any other SQL client to create a database and the relevant tables you need for your application.

CREATE DATABASE FlutterFlowDB;
GO

USE FlutterFlowDB;

CREATE TABLE Users (
    UserID INT PRIMARY KEY,
    UserName NVARCHAR(50),
    UserEmail NVARCHAR(50)
);
GO

 

Step 2: Create an API for Your SQL Server

  FlutterFlow requires access to a REST API to interact with external databases. You can create an API using various technologies such as ASP.NET Core, Node.js, or Python Flask. Here, we will use Node.js and Express.
  • Install Node.js: If you don't have Node.js installed, download and install it from the official Node.js website.
  • Create a New Node.js Project: Initialize a new Node.js project and install the necessary dependencies.

mkdir flutterflow-sql-api
cd flutterflow-sql-api
npm init -y
npm install express mssql body-parser cors

Create the Server: Create an index.js file and set up your server to handle API requests.

const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const sql = require('mssql');

const app = express();
app.use(bodyParser.json());
app.use(cors());

const dbConfig = {
    user: 'your\_username',
    password: 'your\_password',
    server: 'your\_server', 
    database: 'FlutterFlowDB',
    options: {
        encrypt: true,
        trustServerCertificate: true
    }
};

sql.connect(dbConfig, err => {
    if (err) console.log(err);
    console.log('Connected to SQL Server');
});

app.get('/users', (req, res) => {
    new sql.Request().query('SELECT \* FROM Users', (err, result) => {
        if (err) {
            res.status(500).send(err);
        } else {
            res.send(result.recordset);
        }
    });
});

app.listen(3000, () => {
    console.log('API server listening on port 3000');
});

Run Your Server: Start your server by running the following command:

node index.js

 

Step 3: Connect FlutterFlow to Your API

  1. Create a New Project in FlutterFlow: Log into your FlutterFlow account and create a new project. 2. Define API Endpoints: In FlutterFlow, go to the "API Calls" section and add a new API call.
  • URL: http://your_server_ip:3000/users
  • Request Type: GET
Define Response and Headers: Configure the response and headers according to your API.
  • Response Data: Parse the response data to match the structure of your SQL Server data.
 

Step 4: Display Data in FlutterFlow

  1. Add a ListView: Drag and drop a ListView widget to your screen where you want to display the data. 2. Bind API Data: Bind the ListView to your API call.
  • API Call: Select the API call you set up earlier.
  • Response Data: Bind the widgets inside the ListView to the specific fields in your API response (e.g., UserName, UserEmail).
 

Step 5: Test and Debug

  1. Run Your Application: Use the FlutterFlow preview or export the code to run your application on a local emulator or physical device. 2. Verify Data: Ensure that data from your Microsoft SQL Server database appears correctly in your FlutterFlow application. 3. Debug if Needed: If data does not appear correctly, double-check API endpoints, CORS settings, and data bindings in FlutterFlow.  

Conclusion

  Integrating FlutterFlow with Microsoft SQL Server involves setting up a REST API to expose your SQL Server data and configuring the API connection within FlutterFlow. By following these detailed steps, you should be able to create a data-driven mobile application using FlutterFlow and Microsoft SQL Server.

FlutterFlow and Microsoft SQL Server integration usecase

Scenario:

A retail chain wants to enhance its inventory management system by enabling real-time synchronization between their mobile and web apps and their back-end database. They decide to use FlutterFlow to develop the front-end interfaces and Microsoft SQL Server as their primary database solution. The goal is to ensure that sales data, inventory levels, and stock updates are efficiently and accurately captured and managed in their SQL Server database.

Solution: Integrating FlutterFlow with Microsoft SQL Server

App and Interface Development:

  • The retail chain uses FlutterFlow to design intuitive and responsive mobile and web applications for their staff to manage inventory and sales data.
  • The application includes features like scanning product barcodes, updating stock levels, checking inventory, and viewing sales reports.

Setting Up the Integration:

  • The IT team sets up a REST API on their server that acts as a bridge between FlutterFlow and the Microsoft SQL Server database.
  • They configure the API to handle CRUD operations (Create, Read, Update, Delete) on the database.

API Configuration in FlutterFlow:

  • FlutterFlow is configured to connect with the REST API using custom HTTP request actions.
  • Workflows are set up in FlutterFlow to trigger API calls whenever a user performs relevant actions, such as scanning a product or updating stock levels.

Data Management Workflow:

  • When a staff member scans a product barcode, the workflow triggers an API request to fetch product details from the SQL Server database.
  • If a sale is recorded, the data is immediately sent via the API to update the inventory levels in the SQL Server database.
  • Stock adjustments can be made in the app, triggering an API request to update the database in real-time.

Inventory and Sales Monitoring:

  • Managers use the web version of the app to generate reports and monitor inventory levels, sales trends, and stock movements.
  • The integration allows for real-time updates and ensures data consistency across the system.

Benefits:

Real-Time Data Synchronization:

  • Ensures that inventory levels and sales data are always up to date, reducing the risk of stockouts or overstock situations.

Efficiency:

  • Automating the data capture and synchronization process streamlines operations, saving time and reducing manual errors.

Centralized Data Management:

  • All inventory and sales data are stored in Microsoft SQL Server, providing a single source of truth for the retail chain.

Enhanced Reporting:

  • Real-time updates enable more accurate and timely reporting, aiding in better decision-making and strategy formulation.

Scalability:

  • Both FlutterFlow and Microsoft SQL Server are scalable solutions, allowing the system to grow as the business expands.

Conclusion:

By integrating FlutterFlow with Microsoft SQL Server, the retail chain can significantly improve its inventory management process, ensuring real-time synchronization of data, reducing manual errors, and facilitating better decision-making through accurate and timely reports.
