braintree_checkout_flutter #

A Flutter plugin that enables seamless PayPal, Venmo and Card payments using Braintree, with support for native mobile experiences and device data collection for fraud prevention.

⚠️ Note: This plugin currently supports Vault (tokenize only) transactions. You are responsible for capturing the payment server-side using the nonce returned. Full Checkout (automatic capture) is not supported at this time.

Features #

• Native PayPal payment flow
• Native Venmo payment flow
• Native Card payment flow
• Device data collection
• Venmo App availability check

Platform Support #

Installation #

Add the dependency in your pubspec.yaml:

  ),
);

if (result != null) {
  print('Venmo nonce: ${result.nonce}');
}

Card Vault Transaction #

final result = await checkout.tokenizeCard(
  CardRequest(
    token: 'your-client-token-or-tokenization-key',
