A Flutter package that allows you to generate card hashes to be used with pagar.me's payment platform.
Is this safe?
Well, that's something I wondered too when I was looking for a third party package to use to generate card hashes when facing the fact that generating the card_hash using pagarme.js library wasn't neat enough in Flutter.
I began looking into pagar.me's C# and PHP libraries and found out that what they do is basically the process documented here.
So I basically replicated that process.
I tried to keep the code as simple as possible so that people could see that there's no monkey business amidst the lines.
First, add pagarme_flutter_card_hash as a dependency in your pubspec.yaml file.
Then all you have to do is the following:
String pagarMeApiKey = "ek_test_yCRumKDVQgqFkjlQojnTSHgWw7UI5g"; PagarMeCard pagarMeCard = new PagarMeCard( cardHolderName: "John Snow", cardCvv: "235", cardNumber: "5448280000000007", cardExpirationDate: "0620"); PagarMeFlutterCardHash pagarMeFlutterCardHash = new PagarMeFlutterCardHash( pagarMeApiKey: pagarMeApiKey, pagarMeCard: pagarMeCard); String cardHash = await pagarMeFlutterCardHash.generateCardHash(); print(cardHash); //Outputs something like: 1842883_Ha6Q2D/xYkuKXpgbDwy3HnrJpO2oX3c...
P.S.: This package assumes that the card data you are using has already been validated.
