Braintree plugin for Flutter

Braintree for Flutter

A Flutter plugin that wraps the native Braintree Drop-In UI SDKs. Currently only supports Android.

Installation

Add braintree to your pubspec.yaml file:

dependencies:
  ...
  braintree: ^0.1.2

Android

As of version 0.1.0, you must migrate to AndroidX.
In /app/build.gradle, set your minSdkVersion to at least 21.

PayPal / Venmo

In order for your drop-in to support PayPal or Venmo 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.BraintreeBrowserSwitchActivity"
    android:launchMode="singleTask">
    <intent-filter>
        <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" />
    </intent-filter>
</activity>

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:

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

Usage

Import the plugin:

import 'package:braintree/braintree.dart';

Create a drop-in request object:

var 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.');
}

See BraintreeDropInRequest and BraintreeDropInResult for more documentation.
