Step-by-Step Guide on Integrating FlutterFlow with Plaid

Integrating FlutterFlow with Plaid can be a powerful combination to build fintech apps effectively. Follow this detailed step-by-step guide to perform the integration successfully.

Prerequisites

A FlutterFlow account.
A Plaid developer account.
Basic understanding of FlutterFlow and API integration.

Step 1: Set Up Plaid Account

Create a Plaid Developer Account: Visit Plaid Developer Signup and create an account. Follow the on-screen instructions to verify your email and set up your profile.
Create a New Plaid App: Navigate to the Plaid dashboard and click 'Create new App'. Fill in the required details such as app name, country, and other relevant information. Note down the client ID and secret. These will be required for API communication.

Step 2: Prepare FlutterFlow Project

Open FlutterFlow: Log in to your FlutterFlow account and open the project you want to integrate with Plaid.
Set Up API Calls: Navigate to the 'API Calls' section in FlutterFlow. Click on 'Add API Call' to set up new API endpoints required for Plaid.

Step 3: Create Plaid API Calls in FlutterFlow

Auth API Call: Endpoint: POST /link/token/create Request Body:

  
  {
      "client_id": "",
      "secret": "",
      "user": {
        "client_user_id": ""
      },
      "client_name": "",
      "products": ["auth"],
      "country\_codes": ["US"],
      "language": "en",
      "webhook": ""
  }

Headers: Content-Type: application/json Test Call: Use the Test button to check if the API call is working properly.

Get Access Token API Call: Endpoint: POST /item/public\_token/exchange Request Body:
```
  
  {
      "client_id": "",
      "secret": "",
      "public_token": ""
  }
  
  
```
Headers: Content-Type: application/json Test Call: Verify this call with your test public token.

Step 4: Configure Plaid Link SDK

Get Plaid Link SDK: Use the Plaid Link SDK documentation to find the Flutter package needed for integrating Plaid.
Add SDK to FlutterFlow Project: Go to 'Settings' > 'Custom Code' in FlutterFlow. Add the Plaid Flutter SDK package information under 'Packages'.

Write Custom Function: Add a Dart function to trigger Plaid Link and handle the success callback.


import 'package:plaid_flutter/plaid_flutter.dart';

void openPlaidLink() {
  const configuration = LinkConfiguration(
    token: '',
  );
  
  PlaidLink.open(configuration: configuration, onSuccess: (result) {
    // Handle success, get public\_token
    print(result.publicToken);
    
    // Call the API to exchange public_token for access_token
  }, onExit: (exitReason) {
    // Handle exit without success
    print(exitReason);
  });
}

Step 5: Integrate SDK with FlutterFlow UI

Create New Screen: Add a new screen in FlutterFlow where you will trigger the Plaid Link.
Add Button: Drag and drop a button widget on this screen. Set the button's onTap action to call the openPlaidLink custom function created earlier.

Step 6: Test Integration

Run Your App: Run the app on a device or emulator. Navigate to the screen with the button to trigger Plaid Link. Ensure that the Plaid Link flow completes successfully, and you are able to obtain a public\_token.
Complete API Flow: Confirm that the public_token is being exchanged for an access_token via the API calls set up in Step 3.

Step 7: Handle Data and Error Management

Store Access Token: Store the access token securely within your app.
Error Handling: Implement comprehensive error handling in your API calls and SDK integration to ensure a robust and user-friendly app experience.

Conclusion

By following these steps, you should have successfully integrated Plaid with your FlutterFlow app. This setup allows you to leverage Plaid’s financial data APIs in your apps efficiently. For additional customization and features, refer to Plaid’s and FlutterFlow’s official documentation.

FlutterFlow and Plaid integration usecase

Scenario:

A personal finance management startup wants to offer a seamless experience for its users to connect their bank accounts and categorize their expenses. They use FlutterFlow to create a mobile app that allows users to visualize their financial data. To achieve this, they need to integrate the app with Plaid to securely link bank accounts and fetch transaction data.

Solution: Integrating FlutterFlow with Plaid

Account Linking

The startup uses FlutterFlow to design a sleek and user-friendly interface for account linking.
A Plaid Link component is integrated into FlutterFlow, allowing users to securely connect their bank accounts from within the app.

Setting Up the Integration

The startup installs the Plaid API integration within FlutterFlow and configures it using their Plaid API credentials.
Workflows are set up in FlutterFlow to trigger Plaid actions when a user initiates the account linking process.

Data Fetch Workflow

When a user links their bank account through the Plaid Link component, the workflow is triggered.
The linked account data and transaction history are fetched using Plaid API actions configured in FlutterFlow.
Transaction data is then stored securely in the startup's database for further processing and categorization.

Expense Categorization

The startup builds an expense categorization feature within their FlutterFlow app, leveraging the data fetched from Plaid.
They use machine learning models or pre-defined rules to automatically categorize transactions into different spending categories such as groceries, utilities, and entertainment.

User Dashboard

A real-time dashboard is designed in FlutterFlow where users can view their categorized expenses and monitor their spending habits.
Visual elements such as pie charts and bar graphs help users understand their financial status at a glance.

Notifications and Alerts

The app provides personalized notifications and alerts based on the user's spending patterns. For instance, alerts for overspending in any category.
Workflows are set up in FlutterFlow to trigger notifications through app alerts or emails using transaction data from Plaid.

Monitoring and Analytics
