A Flutter plugin for Plaid Link.

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 = PlaidLink(
    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.


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