Create dictionary out of txt file. One alphabet letter per row. Key is letter and value should be iteration of the loop

Question

i got a problem.. I have a txt file that looks like this:

a
b
c
d

One letter per row, there is not two values per row, so nothing to split..

This code works, if I add a second value in my alphabetFile.
dict = {}
with open("alphabet.txt") as alphabetFile:
    for line in alphabetFile:
        (key, val) = line.split()
        dict[int(key)] = val

print(dict)

But I should only have 1 value per row... Im thinking the iteration should be the second value.. but im stuck and tired.. any ideas?

Answer 1

void someFunction(List<User> users) {
  // do something
}

And calling the function:

someFunction(users) ;

EDIT: Okay, it is specifically about a Card.

Well, depends ... if you want to somehow put all user information on one card ... But I assume you want to create a bunch of cards, one for each user?

There is a number of ways to reach that. This is one of the easiest:

for (var user in users)
  Card(
    child: Text('Name: ${user.name}'),
  ),

Answer 2

Type Inference let you send any type of data in functin Create method like this:

void card(var users) {
  // Do whatever you want to do with list 
}

and you can call this card method where you want like this:

card(user)

and you will be done.
