Flutter: New variable from function

Question

I have a variable which gets a value from a function. The function generates a random string from a list. However when I call the variable it has the value from the first time it was called. How do I get the variable to call the function every time so it has a new value each time it is called?

My code is:

player1gen(List players) {
  //players[Random().nextInt(players.length)];
  return players[Random().nextInt(players.length)].toString();
}

String player1 = player1gen(players);

Can you share mode details like where you declared that function and from where you are calling that one ? — Hardik Mehta

You can do

String get player1 => player1gen(players);

@Entrebear While this does what you want, I would advise against it. It is unusual for a getter (which to callers looks like a normal variable access) to return different values. It would be much more readable for player1 to be a function.

@jamesdlin yeah, I agree
