Flutter example show error 500

[alexlovar]

hello, i trying to implement dapi in my app, but the sample is outdated, the base url is incorrect: connect.dapi.co returns 500

i tried with https://connect.dapi.co/v3/connection,

String generateConnectInitializationUrl(){
    var baseUrl = "connect.dapi.co";
    var config = {
      "appKey":.....
    "environment": "sandbox",
      "redirectUri": "https://google.com",
      "countries": ['MX'],
      "isMobile" : "true",
      "isWebview": "true"
    };

    return Uri.https(baseUrl, '/v3/connection', config).toString();

i get the server error 500

can you help me to connect my flutter app?

thanks
