# card_app
## Intro
This is a small mobile application system that allows our admins to submit credit card numbers for validation.
## Requirements
Build a Flutter mobile application that can do the following:
- Allow the user to submit credit card details. Details should include:
Card Number, Card Type, CVV, Issuing Country
- The ability to infer Card Type from Credit Card number would be beneficial.
- Check the specified country to make sure it doesn’t exist in a list of banned countries.
- Make the list of banned countries configurable.
- If the card is valid – store it in local storage.
- Display all the credit cards that have been captured during the session.
- Don’t capture the same card twice.
- Please also add the ability to scan a credit card (examples attached), pre-populate the
card number, and infer the cart type.
- Authorization is not necessary for the purposes of this test.
## How to configure a list of banned countries?
A list of banned countries could be configured by adding a country with the type of cards that are banned, see the code below.
Note: on the list of banned countries we do a lock-up to see if the card type you're providing is not banned and if its banned we block you from saving the card.
```
class Configuration {
final List> bannedListOfCountry = [
{
"russia": ["visa", "master"],
},
{
"iran": ["visa", "master"],
},
{
"Sudan": ["visa", "master"],
},
{
"sudan": ["visa", "master"],
},
{
"syria": ["visa", "master"],
},
{
"north korea": ["visa", "master"],
},
];
}
```
