Step-by-Step Guide on Integrating FlutterFlow with Salesforce
Step 1: Set Up Salesforce
- Create Salesforce Account:
- If you don't have a Salesforce account, visit Salesforce and sign up for a developer account.
- Create a New Connected App:
- Go to Setup in Salesforce by clicking on the gear icon in the top right corner.
- In the Quick Find box, type App Manager and click on it.
- Click New Connected App in the top right corner.
- Fill in the Basic Information such as App Name, API Name, and Contact Email.
- Under the API (Enable OAuth Settings) section, check Enable OAuth Settings.
- Set the “Callback URL” to: http://localhost:3000/oauth/callback.
- Under Selected OAuth Scopes, add Full Access (full) and Perform requests on your behalf at any time (refresh_token, offline_access).
- Click Save and note down the Consumer Key and Consumer Secret displayed after the app is created (you'll need these later).
Step 2: Configure Salesforce API Access
- API Usage:
- Ensure API access is enabled for your Salesforce organization.
- Go to Setup and type Profiles in the Quick Find box.
- Choose the profile used by your Connected App and ensure that the API Enabled checkbox is checked.
Step 3: Set Up FlutterFlow
- Create a Project in FlutterFlow:
- Go to the FlutterFlow website and sign in or create an account.
- Create a new project or open an existing project where you want to integrate Salesforce.
Step 4: Install Required Packages
- HTTP Package:
- Open the PUBSPEC.YAML file in FlutterFlow.
- Add the http package to dependencies:
```
dependencies:
http: ^0.13.3
```
- Oauth2 Package:
- Add the oauth2 package to dependencies:
```
dependencies:
oauth2: ^2.0.0
```
Step 5: Authenticate with Salesforce
- Add Authentication Logic:
- Create a new Dart file in your FlutterFlow project called salesforce\_auth.dart.
- Add the following code to handle Salesforce OAuth2 authentication:
```
import 'package:oauth2/oauth2.dart' as oauth2;
final authorizationEndpoint = Uri.parse('https://login.salesforce.com/services/oauth2/authorize');
final tokenEndpoint = Uri.parse('https://login.salesforce.com/services/oauth2/token');
final identifier = 'YOUR_CONSUMER_KEY'; // Replace with your Consumer Key
final secret = 'YOUR_CONSUMER_SECRET'; // Replace with your Consumer Key
final redirectUrl = Uri.parse('http://localhost:3000/oauth/callback');
var client;
Future
authenticate() async {
final grant = oauth2.AuthorizationCodeGrant(
identifier,
authorizationEndpoint,
tokenEndpoint,
secret: secret,
);
// Redirect the user to the authorization URL
final authorizationUrl = grant.getAuthorizationUrl(redirectUrl);
print('Please go to the following URL:');
print('$authorizationUrl');
print('Sign in and click "Allow", then copy the code from the redirect URL.');
// Once the user has authorized the application, they'll be redirected to
// a URL like http://localhost:3000/oauth/callback?code=...
// Get the authorization code from the URL.
final authorizationResponse = Uri.parse(stdin.readLineSync().trim());
// Use the complete() method to exchange the authorization code for an access token.
client = await grant.handleAuthorizationResponse(authorizationResponse.queryParameters);
}
```
Step 6: Make API Calls to Salesforce
- Create Salesforce API Call Methods:
- Add a new Dart file called salesforce\_api.dart.
- Use the client obtained from the authenticate function to make API calls:
```
import 'salesforce_auth.dart';
Future fetchSalesforceData() async {
if (client != null) {
final response = await client.get(Uri.parse('https://your-instance.salesforce.com/services/data/vXX.X/sobjects/YourObject/'));
if (response.statusCode == 200) {
print('Data fetched successfully');
print(response.body);
} else {
print('Failed to fetch data: ${response.statusCode}');
}
} else {
print('Client is not authenticated');
}
}
```
Step 7: Use Salesforce Data in FlutterFlow
- Integrate API Response in FlutterFlow Widgets:
- Use the fetchSalesforceData method in the appropriate widget's lifecycle methods like initState to fetch data when the widget is created:
```
@Override
void initState() {
super.initState();
// Fetch Salesforce data
fetchSalesforceData().then((data) {
// Update the state with fetched data
setState(() {
// Update your widget with Salesforce data
});
});
}
```
Step 8: Testing
- Run Your Application:
- Ensure all dependencies are installed using flutter pub get.
- Run your Flutter application on a suitable device or emulator.
- Confirm that the application authenticates with Salesforce and fetches data as expected.
Step 9: Handle Errors and Edge Cases
- Error Handling:
- Implement proper error handling in your API methods.
- Check for network errors, HTTP status codes, and invalid responses.
Step 10: Secure Sensitive Data
- Secure Storage:
- Avoid hardcoding sensitive data like Consumer Key, Consumer Secret, and API tokens.
- Use secure storage options provided by Dart and Flutter, such as the flutter_secure_storage package, to store sensitive information.
By following these detailed steps, you will successfully integrate FlutterFlow with Salesforce, enabling you to leverage Salesforce data and functionality within your FlutterFlow application.
