Introduction:
In modern enterprises, legacy systems like SAP, Salesforce, and Oracle have become fundamental to day-to-day operations, yet they often exist in silos. These systems, while powerful, do not always communicate well with each other, leading to fragmented workflows and inefficiencies. The challenge for developers is to integrate these systems seamlessly while maintaining robust performance, consistency, and security.
Custom Flutter development provides a game-changing solution to bridge the gaps between these legacy silos. With its cross-platform capabilities, Flutter allows businesses to develop unified mobile applications that interact with SAP, Salesforce, and Oracle systems, providing a single, cohesive user experience.
In this blog, we’ll explore how custom Flutter development integrates these legacy systems into one cohesive application, showcasing the key benefits and challenges of this integration, as well as providing technical insights and examples on how to achieve seamless connectivity.
The Challenge of Legacy Systems in Enterprises
Legacy systems like SAP, Salesforce, and Oracle are highly specialized but often operate independently of each other, creating inefficiencies and silos of information. These systems have been around for years, providing robust solutions for enterprise resource planning (ERP), customer relationship management (CRM), and database management, respectively. However, integrating data across these platforms can be a complex task for developers.
The lack of a unified user interface often leads to user frustration as employees must access multiple systems to retrieve and input data. Moreover, manual data transfer, duplicate data entry, and inconsistent updates between systems are common issues faced by businesses that use these tools in parallel.
As businesses grow, so does the need for systems that communicate seamlessly, ensuring consistent, real-time data and workflows that don’t require switching between different applications. This is where Flutter can play a transformative role.

How Flutter Bridges the Legacy Silos
The Power of One Codebase
One of Flutter’s most attractive features is its ability to work across multiple platforms using a single codebase. This drastically reduces development time and costs while ensuring that updates and features are synchronized across iOS, Android, and web platforms.
For enterprises with complex systems like SAP, Salesforce, and Oracle, Flutter can act as a unifying bridge that allows data from all these sources to be integrated and displayed within one app. By using a common codebase, businesses eliminate the need to manage multiple versions of the app for different platforms.
dart code:
// Example of a simple Flutter app integrating multiple systems
class DataFetcher extends StatefulWidget {
@override
_DataFetcherState createState() => _DataFetcherState();
}
class _DataFetcherState extends State<DataFetcher> {
String dataFromSAP = '';
String dataFromSalesforce = '';
String dataFromOracle = '';
@override
void initState() {
super.initState();
fetchData();
}
void fetchData() async {
// Simulate fetching data from APIs of SAP, Salesforce, Oracle
dataFromSAP = await fetchFromSAP();
dataFromSalesforce = await fetchFromSalesforce();
dataFromOracle = await fetchFromOracle();
setState(() {});
}
Future<String> fetchFromSAP() async {
// Replace with actual SAP integration logic
return "SAP Data";
}
Future<String> fetchFromSalesforce() async {
// Replace with actual Salesforce integration logic
return "Salesforce Data";
}
Future<String> fetchFromOracle() async {
// Replace with actual Oracle integration logic
return "Oracle Data";
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Unified Data from Legacy Systems")),
body: Column(
children: <Widget>[
Text('Data from SAP: $dataFromSAP'),
Text('Data from Salesforce: $dataFromSalesforce'),
Text('Data from Oracle: $dataFromOracle'),
],
),
);
}
}
The above example demonstrates how a single Flutter app can fetch and display data from multiple legacy systems using asynchronous calls to APIs. By pulling in data from SAP, Salesforce, and Oracle and displaying it in the app, the user is provided with a unified view without switching between applications.
Cross-Platform Compatibility
Custom Flutter apps allow enterprises to build cross-platform solutions, meaning businesses can have a single application that works seamlessly across iOS, Android, and even web platforms. This is particularly important for enterprises where users may be working on different devices.
By using Flutter, businesses can ensure that SAP data, Salesforce CRM, and Oracle database information are available in real-time, across devices, ensuring that the enterprise remains agile and responsive to user demands.
Seamless Communication Across Systems
Flutter provides excellent API integration capabilities. Whether using RESTful APIs, GraphQL, or WebSockets, Flutter can integrate with SAP, Salesforce, and Oracle seamlessly. In this case, the Flutter app acts as a middleware that interacts with each legacy system’s APIs to pull or push data as required.
- SAP: Using SAP’s APIs (such as SAP Cloud Platform Integration), you can pull data like purchase orders, inventory updates, and more.
- Salesforce: Salesforce offers a variety of APIs (like REST API and Bulk API) that allow for easy integration with mobile apps.
- Oracle: Oracle’s database services can be accessed through Oracle REST Data Services (ORD) or via direct database connections using ODBC or JDBC.
SAP Integration with Flutter
Leveraging SAP Data for Custom Flutter Applications
Integrating SAP with Flutter allows enterprises to access critical ERP data in real-time. For instance, businesses can fetch data like inventory levels, order processing statuses, and financial reports directly from SAP into a Flutter-based app.
The SAP Cloud Platform provides various APIs that can be integrated with Flutter using packages like http or graphql_flutter. This enables Flutter developers to create apps that present ERP data in real-time.
dart code:
import 'package:http/http.dart' as http;
Future<String> fetchFromSAP() async {
final response = await http.get(Uri.parse('https://sap-api-endpoint.com/data'));
if (response.statusCode == 200) {
return response.body; // Process SAP data here
} else {
throw Exception('Failed to load SAP data');
}
}
Real-Time SAP System Sync with Flutter Apps
Real-time synchronization ensures that the data displayed in the app is always current. Using WebSockets or Push Notifications, businesses can keep users updated without having to refresh or reload the app.
Salesforce and Flutter: A Unified Customer View
Salesforce Data in Flutter Applications
Integrating Salesforce with Flutter enhances the user experience by providing a single, unified view of customer data. Sales teams can have customer insights, lead tracking, and sales activity displayed on their mobile devices, improving decision-making in real-time.
The Salesforce REST API makes it easy to pull data such as customer records, opportunities, and activities into a Flutter app. By combining Salesforce data with other systems, like SAP or Oracle, businesses can provide a holistic view of customer interactions.
dart code:
Future<String> fetchFromSalesforce() async {
final response = await http.get(Uri.parse('https://salesforce-api-endpoint.com/data'));
if (response.statusCode == 200) {
return response.body; // Process Salesforce data here
} else {
throw Exception('Failed to load Salesforce data');
}
}
Oracle and Flutter: Bridging the Database Divide
Simplifying Oracle Database Access Through Flutter
For enterprise apps that rely heavily on Oracle databases, integrating Oracle with Flutter apps simplifies the access to large datasets. Flutter can use direct API calls or middleware to fetch real-time data from Oracle databases, enabling users to view business-critical data on their mobile devices.
Synchronizing Oracle Data Across Mobile Platforms
By utilizing Oracle REST Data Services (ORD) or Oracle Cloud Infrastructure (OCI), developers can synchronize Oracle data with Flutter apps, ensuring that the app remains connected to the Oracle database in real-time. This integration allows for the mobile access of important data, such as inventory, sales, or financial records.
dart code:
Future<String> fetchFromOracle() async {
final response = await http.get(Uri.parse('https://oracle-api-endpoint.com/data'));
if (response.statusCode == 200) {
return response.body; // Process Oracle data here
} else {
throw Exception('Failed to load Oracle data');
}
}
