Flutter plugin that wraps the native Braintree SDKs. Enables payments with credit cards, PayPal, Google Pay and more.

Braintree for Flutter #

A Flutter plugin that wraps the native Braintree SDKs. Unlike other plugins, this plugin not only lets you start Braintree's native Drop-in UI, but also allows you to create your own custom Flutter UI with Braintree functionality.

Installation #

Add flutter_braintree to your pubspec.yaml file:

  flutter_braintree: <version>

Android #

You must migrate to AndroidX.
In /app/build.gradle, set your minSdkVersion to at least 21.


Card.io enables credit card scanning so as to remove the need to type in credit card details manually. This feature became optional in flutter_braintree version 0.6.0 to potentially reduce app sizes. To enable it for the Braintree Drop-in UI, add the following line to your app level build.gradle file:

dependencies {
    implementation 'io.card:android-sdk:5.+'

PayPal / Venmo / 3D Secure

In order for this plugin to support PayPal, Venmo or 3D Secure payments, you must allow for the browser switch by adding an intent filter to your AndroidManifest.xml (inside the <application> body):

<activity android:name="com.braintreepayments.api.DropInActivity"
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="${applicationId}.braintree" />
<activity android:name="com.braintreepayments.api.ThreeDSecureActivity" android:theme="@style/Theme.AppCompat.Light" android:exported="true">

Important: Your app's URL scheme must begin with your app's package ID and end with .braintree. For example, if the Package ID is com.your-company.your-app, then your URL scheme should be com.your-company.your-app.braintree. ${applicationId} is automatically applied with your app's package when using Gradle. Note: The scheme you define must use all lowercase letters. If your package contains underscores, the underscores should be removed when specifying the scheme in your Android Manifest.

Google Pay

Add the wallet enabled meta-data tag to your AndroidManifest.xml (inside the <application> body):

<meta-data android:name="com.google.android.gms.wallet.api.enabled" android:value="true"/>

iOS #

You may need to add or uncomment the following line at the top of your ios/Podfile:

platform :ios, '12.0'

Warning: Device data collection is not yet supported for iOS.

PayPal / Venmo / 3D Secure

In your App Delegate or your Runner project, you need to specify the URL scheme for redirecting payments as following:


Moreover, you need to specify the same URL scheme in your Info.plist:


See the official Braintree documentation for a more detailed explanation.

Usage #

You must first create a Braintree account. In your control panel you can create a tokenization key. You likely also want to set up a backend server. Make sure to read the Braintree developer documentation so you understand all key concepts.

In your code, import the plugin:

import 'package:flutter_braintree/flutter_braintree.dart';

You can then create your own user interface using Flutter or use Braintree's drop-in UI.

Flutter UI #

Credit cards

Create a credit card request object:

final request = BraintreeCreditCardRequest(
  cardNumber: '4111111111111111',
  expirationMonth: '12',
  expirationYear: '2021',
  cvv: '367'

Then ask Braintree to tokenize it:

BraintreePaymentMethodNonce result = await Braintree.tokenizeCreditCard(
   '<Insert your tokenization key or client token here>',


Create a PayPal request object:

final request = BraintreePayPalRequest(amount: '13.37');

Or, for the Vault flow:

final request = BraintreePayPalRequest(
  billingAgreementDescription: 'I hereby agree that flutter_braintree is great.',

Then launch the PayPal request:

BraintreePaymentMethodNonce result = await Braintree.requestPaypalNonce(
   '<Insert your tokenization key or client token here>',
if (result != null) {
  print('Nonce: ${result.nonce}');
} else {
  print('PayPal flow was canceled.');

Braintree's native drop-in #

Create a drop-in request object:

final request = BraintreeDropInRequest(
  clientToken: '<Insert your client token here>',
  collectDeviceData: true,
  googlePaymentRequest: BraintreeGooglePaymentRequest(
    totalPrice: '4.20',
    currencyCode: 'USD',
    billingAddressRequired: false,
  paypalRequest: BraintreePayPalRequest(
    amount: '4.20',
    displayName: 'Example company',

Then launch the drop-in:

BraintreeDropInResult result = await BraintreeDropIn.start(request);

Access the payment nonce:

if (result != null) {
  print('Nonce: ${result.paymentMethodNonce.nonce}');
} else {
  print('Selection was canceled.');

To increase the chances of success with 3DS2 challenge is possible to add additional information about the user as mentioned in the guide to Migrate to 3D Secure 2.

var request = BraintreeDropInRequest(
  clientToken: '<Insert your client token here>',
  collectDeviceData: true,
  requestThreeDSecureVerification: true,
  email: "test@email.com",
  amount: "0,01",
  billingAddress: BraintreeBillingAddress(
    givenName: "Jill",
    surname: "Doe",
    phoneNumber: "5551234567",
    streetAddress: "555 Smith St",
    extendedAddress: "#2",
    locality: "Chicago",
    region: "IL",
    postalCode: "12345",
    countryCodeAlpha2: "US",
  cardEnabled: true,
