Plaid Link for Flutter. Integrates the native iOS, Android and Web SDKs.

Plaid Link for Flutter

A Flutter plugin for Plaid Link.

This plugin integrates the native SDKs:

• Plaid Link iOS SDK
• Plaid Link Android SDK
• Plaid Link JavaScript SDK

Feel free to leave any feedback here.

Requirements

In order to initialize Plaid Link, you will need to create a link_token at /link/token/create. After generating a link_token, you'll need to pass it into your app and use it to launch Link:

...

LinkConfiguration configuration = LinkTokenConfiguration(
    token: "<GENERATED_LINK_TOKEN>",
);

PlaidLink.open(configuration: configuration)

...

A link_token can be configured for different Link flows depending on the fields provided during token creation. It is the preferred way of initializing Link going forward. You will need to pass in most of your Link configurations server-side in the /link/token/create endpoint rather than client-side where they previously existed.

If your integration is still using a public_key to initialize Plaid Link, the LinkConfiguration class has support for it. Check the migration guide to upgrade your app to the link_token flow.

Installation

Add plaid_flutter as a dependency in your pubspec.yaml file.

iOS

Requirements

• iOS version >= 14.0
• Xcode 14 or greater

(Identity Verification only) - Enable camera support

When using the Identity Verification product, the Link SDK may use the camera if a user needs to take a picture of identity documentation. To support this workflow, add a NSCameraUsageDescription entry to your ios/Runner/Info.plist with an informative string.

OAuth configuration

If your integration uses only Identity Verification or Monitor, this steps can be skipped; they are mandatory otherwise.

Registering your redirect URI:

• Sign in to the Plaid Dashboard and go to the Team Settings -> API page.
• Next to Allowed redirect URIs click Configure then Add New URI.
• Enter your redirect URI, which you must also set up as a Universal Link for your application, for example: https://app.example.com/plaid/.
• Click Save Changes

These redirect URIs must be set up as Universal Links in your application.

More info at https://plaid.com/docs/link/ios.

Android

Requirements

Gradle Configuration

Go to the project level android/app/build.gradle and make sure you are using a minSdk >= 21

(Identity Verification only) - Enable camera support

If your app uses Identity Verification, a user may need to take a picture of identity documentation or a selfie during the Link flow. To support this workflow, the CAMERA, WRITE_EXTERNAL_STORAGE, RECORD_AUDIO, and MODIFY_AUDIO_SETTINGS permissions need to be added to your application's AndroidManifest.xml.

Register your App ID

• Sign in to the Plaid Dashboard and go to the Team Settings -> API page.
• Next to Allowed Android Package Names click Configure then Add New Android Package Name.
• Enter your package name, for example com.plaid.example.
• Click Save Changes.

More info at https://plaid.com/docs/link/android.

Web

Requirements

Include the Plaid Link initialize script on your main HTML page.

<script src="https://cdn.plaid.com/link/v2/stable/link-initialize.js"></script>

More info at https://plaid.com/docs/link/web.

'Close' method not implemented

Hey @jorgefspereira,

I'm listening to the events from Plaid, and in some scenarios I need to close the Plaid window and return to my app.
In iOS this works great by calling PlaidLink.close();
However, in Android it doesn't work and I noticed the close method has no implementation.
Is there a reason for that? How can I add the close logic?

Thanks,
Avi

Release 2.0.9 soon?

Do you have any plans to release 2.0.9?
Or maybe you can provide steps how to migrate from 1.x to 2.x package?
I tried to fetch from GitHub, but unfortunately get an exception about linking.
Steps:
Create new project, add reference to flutter_plaid and try to build

Unable to continue with Oauth result

Hi,

I am using this plugin which works great but I am currently trying to implement Oauth.
I am using the Token Configuration for my Link workflow.

Everything is setup with App Links, the bank's webpage opens and comes back in my App with the "Oauth_state_id" appended to the URI.

However, I do not know what to do with it to continue the Link process once I have it.

I have noticed that the Link iOS SDK exposes a "continue" method to pass the redirectURI with but such method is not exposed in this plugin.

Can you please help me?

I tried to

Account Subtype error: Investment > Brokerage

Hi,

I think there's an issue when specifying investment account type and brokerage subtype.

_plaidLink = PlaidLink(
      clientName: "Client Name",

Plugin requiring minSdkVersion 21

Hello,

Thanks for this but I can't seem to get this plugin to work... it requires minSdkVersion 21 instead of 16 and I can't change that because it will break other plugins (like Google Firebase). Is there a way around this? Here's the error...
"Error: uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library"

Thanks,

Update to handle new plaid link

Incredible job on this repo,

I'm not so familiar with java/swift otherwise I would try to implement this myself, but is there any way you can make a branch to support the latest plaid link requirementes? Thanks!

on iOS. Any ideas?

verificationStatus is allways NULL

Since the version 1.1.4 verification_status is added on success callback, but the value is always NULL although using Same Day Micro-deposits flow.

I think should add aux.put("verification_status", a.getVerificationStatus()); after this line for android

Add multiple countries

It would be really awesome if countryCodes can be added to support more countries

PlaidLink - update existing item

Hi, is it possible to pass in an existing public_token in order to re-link an existing item? I believe you would only need to pass in the token param. See below.

Thanks!

Firestore structure and security rules for storing user data?

Could you share a best practice setup with Cloud Firestore for data retrieved via Plaid?

We will probably need some battle hardened security rules.

Feature request

It would be amazing if you could add Android support for this api?

How to hide plaid logo in app?

I want to hide plaid identity in plaid_flutter webview. How to do that?

web support

Hi,

Adding web support should be trivial. Is anybody working on it already?

There's an implementation already that could be merged perhaps?

https://github.com/firelab-app/plaid_link/blob/master/lib/plaid_link_web.dart

OAuth support

Some institutions use an OAuth authentication flow, does the library offer support for those orgs?

According to their docs once you get the oauth_state_id from the url params you need to dismiss the old Link object and create a new one and pass the oauth_state_id to the new config.

Upgrade to Flutter 2 and migrate to Dart null-safety

how to create a link token?

Not an issue with this package but I'm having a lot of trouble creating a link token and I was hoping for some guidance. I've read the plaid documentation but it doesn't help at all. I tried using cloud functions. I'm using nodejs and I installed the plaid npm package so that I can use createLinkToken(). Does the /link/token/create endpoint need to be in my cloud function? I tried that but nothing works. Please advise

Thank you for an awesome package, btw

URI Redirect

How do i add a URI Redirect to the Plaid Link Configuration?

I've had a look at your code and I can't see any support for it. Is there a way to add it myself or has it just not been implemented yet?

Keyboard not popping up when testing with iOS simulator

The keyboard is not showing when I try to enter the User login details in Plaid interface in the iOS simulator.

Can you give me a solution to this problem?

Here is the exact code I used"

import 'dart:convert';

import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'package:plaid_flutter/plaid_flutter.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  PlaidLink _plaidLinkToken;
  var newpublicToken;
  var CLIENT_ID = "NTER YOUR PLAID CLIENT ID";
  var SECRET = "ENTER YOUR PLAID SECRET";
  var unique_per_user = "new_user";

  @override
  void initState() {
    super.initState();
    getLinkToken();
  }

  getLinkToken() async {
    var headers = {
      'Content-Type': 'application/json',
    };

    var data =
        '{ "client_id": "$CLIENT_ID", "secret": "$SECRET", "user": { "client_user_id": "$unique_per_user" }, "client_name": "Plaid App", "products": ["auth"], "country_codes": ["US"], "language": "en", "webhook": "https://sample-web-hook.com", "account_filters": { "depository": { "account_subtypes": ["checking"] } } }';

    var res = await http.post('https://sandbox.plaid.com/link/token/create',
        headers: headers, body: data);
    if (res.statusCode != 200)
      throw Exception('http.post error: statusCode= ${res.statusCode}');
    print(res.body);

    Map<String, dynamic> responseJson = json.decode(res.body);
    var response_link_token = responseJson['link_token'];
    print(response_link_token);

    LinkConfiguration linkTokenConfiguration = LinkConfiguration(
      linkToken: "$response_link_token",
    );

    _plaidLinkToken = PlaidLink(
      configuration: linkTokenConfiguration,
      onSuccess: _onSuccessCallback,
      onEvent: _onEventCallback,
      onExit: _onExitCallback,
    );
  }

  void _onSuccessCallback(String publicToken, LinkSuccessMetadata metadata) {
    print("onSuccess: $publicToken, metadata: ${metadata.description()}");
    newpublicToken = publicToken;
  }

  void _onEventCallback(String event, LinkEventMetadata metadata) {
    print("onEvent: $event, metadata: ${metadata.description()}");
  }

  void _onExitCallback(String error, LinkExitMetadata metadata) {
    print("onExit: $error, metadata: ${metadata.description()}");
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Container(
          width: double.infinity,
          color: Colors.lightBlue,
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              RaisedButton(
                onPressed: () => _plaidLinkToken.open(),
                child: Text("Open Plaid Link (Link Token)"),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

_plaidLink.open() shows empty popup

I'm trying to launch Link in Simulator using the linkTokenConfiguration, pretty much following the Example.

Here's my current code for this:

class PlaidFour extends StatefulWidget {
  final String linkToken;
  PlaidFour({Key key, @required this.linkToken}) : super(key: key);
  static const id = 'plaid_screen_id';

  @override
  _PlaidFourState createState() => _PlaidFourState();
}

class _PlaidFourState extends State<PlaidFour> {
  PlaidLink _plaidLink;

  @override
  void didChangeDependencies() {
    super.didChangeDependencies();
    final user = Provider.of<User>(context);
    final HttpsCallable callable = CloudFunctions.instance
        .getHttpsCallable(functionName: 'addItem')
          ..timeout = const Duration(seconds: 30);

    LinkConfiguration linkTokenConfiguration = LinkConfiguration(
      linkToken: widget.linkToken,
    );

    print('linkTokenConfiguration: $linkTokenConfiguration');
    _plaidLink = PlaidLink(
      configuration: linkTokenConfiguration,
      onSuccess: (publicToken, metadata) async {
        print("UID: ${user.uid} onSuccess: $publicToken metadata: $metadata");
        try {
          final HttpsCallableResult result = await callable.call(
            <String, dynamic>{
              'public_token': publicToken,
              'user_id': user.uid,
            },
          );
          print('addItem function result: ${result.data}');
        } on CloudFunctionsException catch (e) {
          print('caught firebase functions exception');
          print(e.code);
          print(e.message);
          print(e.details);
        } catch (e) {
          print('caught firebase functions generic exception');
          print(e);
        }
      },
      onEvent: (event, metadata) {
        print("onEvent: $event metadata: $metadata");
      },
      onExit: (error, metadata) {
        print("onExit: $error, onExit: $metadata");
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    print('PlaidFour linkToken: ${widget.linkToken}');
    return MaterialApp(
      home: Scaffold(
        body: Container(
          width: double.infinity,
          color: Colors.lightBlue,
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              RaisedButton(
                onPressed: () => _plaidLink.open(),
                child: Text("Open Plaid Link"),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

But for some reason when clicking 'Open Plaid Link' the popup is empty and won't show Link:

No errors or anything in my console. Just the empty popup. I'm able to successfully print the linkToken in the widget.

Any suggestions for how to resolve this would be very appreciated!

Unsure how to connect the client to the server

Sorry if this is a stupid question I'm quite new at this. I was looking through the closed issues to see what I should do but I'm a bit stuck.

I followed the steps at https://plaid.com/docs/link/android/ and I am stuck on the Link Token bit. In the most recent issue related to this and in the plaid documentation there is something about the link_token being created by the apps server and passed through the apps client through an endpoint.

Im assuming that I'll have to host this code and I would change the android_package_name to the package name I've chosen and the same goes for the client name. I also understand that inside the example main.dart, the LinkTokenConfiguration bit will create a new link token from the server.

How would I connect the client to the server and what would I use for the endpoint in the LinkTokenCreateRequest function?

Error when running on Web

I am getting this error when trying to run on web. Everything is working well on Android. I have followed all of the instructions that I can find. Any help would be greatly appreciated.

thanks!

security vulnerabilities in deps

Hi @jorgefspereira !

Plaid's security team has completed their review of this project and there are a couple of dependencies that were picked up by our vulnerability scanner as having potential issues. They would like these to be fixed before we can officially endorse the project. Would you be able to take a look and resolve them if possible?

They are:

plaid_flutter/android	com.google.code.gson:[email protected]	Deserialization of Untrusted Data	High
plaid_flutter/android	com.google.protobuf:[email protected]	Denial of Service (DoS)	High
plaid_flutter/android	org.bouncycastle:[email protected]	Information Exposure	High
plaid_flutter/android	org.bouncycastle:[email protected]	Insecure Encryption	High

Thanks! Let me know if you need any more info or if it's not possible to resolve all of these.

Unsure how to generate link token following the steps

I tried using the Legacy but I think it has been removed ever since the update, and following their documentation has not given me luck. I was hoping if anyone would share the steps they did to get the token.

Add docs for using `continueWithRedirectUri` method

It might be helpful to have some docs around the use of continueWithRedirectUri method and implementing OAuth in general using this plugin as the available tutorials might not come as straightforward in native iOS, eg. like this one.

[feature request] onExit callback should return error_code

Currently onExit returns an error message (for example: "the provided credentials were not correct") that doesn't look anything in the official plaid documentation. It would be more useful to return error data such as what's returned in the onEvent callback like error_type, error_code, error_message (but error_code is sufficient).

Thanks for a great package :)

onSuccess MetaData: null account.id

Since the new rollout of Plaid link, the account.id in the metadata variable passed into onSuccess has been null for me. Name, mask, and type are all there...no id though!

Running on iOS.

Plaid Link opens briefly and closes with error. "Error: Invalid env: "tartan"

"Error: Invalid env: "tartan". env must be "sandbox", "development" or "production"."

This is the error I am receiving. I have looked through the code and do not have a way to forcibly provide these details. It is important to note that SOMETIMES it works fine and Link opens properly. But 50% of the time it fails to open with this error.

I am also receiving errors related to font
Access to font at 'https://cdn.plaid.com/link/2.0.1097/assets/fonts/cern-regular.woff2' from origin 'https://secure.plaid.com' has been blocked by CORS policy:

Would like some better understanding on what can be done to ensure Plaid Link opens everytime successfully.
I am currently using Plaid in development mode.

Pods install failed due to plaid

[!] CocoaPods could not find compatible versions for pod "Plaid":
  In snapshot (Podfile.lock):
    Plaid (= 2.2.0)

  In Podfile:
    plaid_flutter (from `.symlinks/plugins/plaid_flutter/ios`) was resolved to 0.0.1, which depends on
      Plaid (= 2.3.1)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Plaid` inside your development pod `plaid_flutter`.
   You should run `pod update Plaid` to apply changes you've made.

Exception has occurred.

Exception has occurred.
MissingPluginException (MissingPluginException(No implementation found for method open on channel plugins.flutter.io/plaid_flutter))

I'm new to this. could you please help me out? Thanks

Futures instead of callbacks

It would be great if the open function would return a future with the linkToken instead of having to specify the onSuccess/onError callbacks. Any ideas on how this could be solved?

Thanks

Unhandled Exception: MissingPluginException(No implementation found for method open on channel plugins.flutter.io/plaid_flutter)

I am using v0.2.2
I got this error when build on android:
Unhandled Exception: MissingPluginException(No implementation found for method open on channel plugins.flutter.io/plaid_flutter)

I've added this on build.gradle:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

I have set the minimum api to 21.
in iOS it built and works fine.

in main/java/io/flutter/plugins/GeneratedPluginRegistrant.java plugin has been registered.

what am I doing wrong?

thank you
