How to integrate FlutterFlow with Mailgun?

Step 1: Create a Mailgun Account

 
  • Go to Mailgun’s website: Navigate to Mailgun and click on the 'Sign Up' button.
  • Fill in the required details: Provide the necessary information such as your name, email address, and password. Complete the signup process.
  • Confirm your email: Check your email inbox for a confirmation email from Mailgun and follow the instructions to verify your email address.
 

Step 2: Set Up Your Domain in Mailgun

 
  • Log in to your Mailgun account: Once logged in, navigate to the 'Domains' section.
  • Add a new domain: Click on the 'Add New Domain' button.
  • Verify the domain: You will be required to verify your domain by adding DNS records. Follow the instructions provided to add the necessary TXT, MX, and CNAME records to your domain's DNS settings.
  • Wait for verification: It might take some time for the DNS changes to propagate and for Mailgun to verify your domain.
 

Step 3: Obtain Your Mailgun API Key

 
  • Navigate to the API keys section: In your Mailgun dashboard, go to the 'API Security' section.
  • Copy the API Key: Locate the private API key for your account and copy it. This will be used in FlutterFlow to authenticate your requests.
 

Step 4: Set Up a New Project in FlutterFlow

 
  • Log in to FlutterFlow: If you don’t already have an account, sign up at FlutterFlow.
  • Create a New Project: Once logged in, click on the 'Create New' button to start a new project.
  • Choose a Template or Start from Scratch: Follow the steps to create your new project either using a template or starting from scratch.
 

Step 5: Add Dependencies to Your FlutterFlow Project

 
  • Open the 'Settings': Navigate to your project's settings in FlutterFlow.
  • Go to 'Pubspec.yaml' file: Add the dependencies needed for HTTP requests. You will typically need the `http` package to interact with Mailgun’s API.
          
    dependencies:
      flutter:
        sdk: flutter
      http: ^0.13.3
          
        
 

Step 6: Create a Service to Send Emails in FlutterFlow

 
  • Create a New Dart File: Go to the 'Code' section in FlutterFlow and create a new Dart file, e.g., `mailgun_service.dart`.
  • Write the HTTP Request Code: Add the following code to send emails using Mailgun's API:
        
    import 'dart:convert';
    import 'package:http/http.dart' as http;
    
    class MailgunService {
      final String domain = 'yourdomain.com'; // Replace with your Mailgun domain
      final String apiKey = 'your-api-key'; // Replace with your Mailgun API key
      final String baseUrl = 'https://api.mailgun.net/v3';
    
      Future<void> sendEmail(String to, String subject, String text) async {
        final String url = '$baseUrl/$domain/messages';
        
        final response = await http.post(
          Uri.parse(url),
          headers: {
            'Authorization': 'Basic ' + base64Encode(utf8.encode('api:$apiKey')),
            'Content-Type': 'application/x-www-form-urlencoded',
          },
          body: {
            'from': '[email protected]', // Replace with your email
            'to': to,
            'subject': subject,
            'text': text
          },
        );
    
        if (response.statusCode == 200) {
          print('Email sent successfully.');
        } else {
          print('Failed to send email: ${response.body}');
        }
      }
    }
        
        
 

Step 7: Integrate the Service in Your FlutterFlow Project

 
  • Access the Email Function: Use the MailgunService in your app wherever you need to send an email.
  • Example Usage:
        
    import 'mailgun\_service.dart';
    
    // Create an instance of the service
    final mailgunService = MailgunService();
    
    // Call the sendEmail function
    void sendTestEmail() {
      mailgunService.sendEmail(
        '[email protected]', // Replace with the recipient's email
        'Test Subject',
        'This is a test email sent from FlutterFlow integration.'
      );
    }
        
        
 

Step 8: Trigger the Email Sending Function in Your App

 
  • Add a Button to Your UI: In FlutterFlow, drag and drop a button widget onto your screen.
  • Configure the Button: Set up the button to call the `sendTestEmail` function when tapped.
        
    onPressed: () {
      sendTestEmail();
    }
        
        
 

Step 9: Test Your Integration

 
  • Run Your FlutterFlow Project: Build and run your FlutterFlow project on a simulator or physical device.
  • Trigger the Email Send: Tap on the button you configured to send an email.
  • Check the Recipient’s Inbox: Verify that the email has been received as intended.
 

Step 10: Handle Errors and Edge Cases

 
  • Error Handling: Implement additional error handling and logging to ensure that any issues with sending emails are properly managed.
  • Test Different Scenarios: Test the integration with different email addresses and content to ensure that everything works as expected.
