Because mercadopago_sdk >=1.3.0 depends on test ^1.16.8 which depends on analyzer ^1.0.0, mercadopago_sdk >=1.3.0 requires analyzer ^1.0.0.

So, because audasiuz depends on both analyzer ^0.40.6 and mercadopago_sdk ^1.3.0, version solving failed. pub get failed (1; So, because audasiuz depends on both analyzer ^0.40.6 and mercadopago_sdk ^1.3.0, version solving failed.)

According MercadoPago documentation to generate a preference, you need a Public Key and Access Token and not a Client Id and Client Secret.

I tried to get preference sending using de constructor MP('public_key','access_token') but didn't work, so i suppose that the Client id is not the same as Public Key and Client Secret is not the same as Access Token.

Im trying to get users or pay method and I have this error:

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: NoSuchMethodError: The getter 'keys' was called on null. Receiver: null Tried calling: keys

If a try by the URL by web i receive the information.

The caller is:

mp.get("/v1/payment_methods", authenticate: true, params: {});

Thanks!

hello! I'm having some problems trying to implement the funcionality "getpreference" It lead's me to an error message.

the code is:

} }

it gives me the error message:

Because mercadopago_sdk 1.2.0 depends on http ^0.12.0 and no versions of mercadopago_sdk match >1.2.0 <2.0.0, mercadopago_sdk ^1.2.0 requires http ^0.12.0. So, because .... depends on both http ^0.13.0 and mercadopago_sdk ^1.2.0, version solving failed.

Add new changes

1. Using factory

   var mp = MP.fromAccessToken('MYACCESSTOKEN');
   var preference = {
           "items": [
               {
                   "title": "Test",
                   "quantity": 1,
                   "currency_id": "USD",
                   "unit_price": 10.4
               }
           ]
       };
   var result = await mp.createPreference(preference);```
   
   

2. Using method

   var mp = MP("CLIENT_ID", "CLIENT_SECRET");
   var preference = {
           "items": [
               {
                   "title": "Test",
                   "quantity": 1,
                   "currency_id": "USD",
                   "unit_price": 10.4
               }
           ]
       };
   // Change access token
   mp.setAccessToken('MYACCESSTOKEN');
   var result = await mp.createPreference(preference);```
   

I am developing a marketplace in Flutter using this package to access the MercadoPago API to build a Transparent Checkout. However, to add a card, I believe I need the createCardToken function. But it doesn't exist in the package, right? How should I implement the adding card feature?

Como ya lo han reportado, el "quemar" tanto el client id como el client secret y el access token es una brecha de seguridad gigante por lo que no es recomendado el uso de este plugin mientras no haya manera de cifrar esas credenciales.

Can you tell me if with this api i can create a pending payment to be released in X days? I need to meet two scenarios:

1. user makes a purchase, I hold this amount for 2 days, after two days I cancel and return it, like a guarantee.
2. user makes a purchase, I hold for 2 days, after the two days I effect the payment.

Any chance we could get a basic payment flow as an example? I've read the doc but I think I'm missing a lot of information.

I have created this so far, but then I'm not sure what's next on the list.

Future<void> startMP() async {
    MP mercadoPago = MP('6924219732628689', 'yd5kmBOBHhXE24GuOVK9iozt5D8vjyY2');

    String token = await mercadoPago.getAccessToken();

    var payer = {'email': '[email protected]'};

    var preference = {
      "items": [
        {
          "title": "Test01",
          "quantity": 1,
          "currency_id": "USD",
          "unit_price": 0.01,
          "payer": payer,
        }
      ],
    };

    var result = await mercadoPago.createPreference(preference);

    
  }

What's next? Thank you.
