How can I get random items from a list and then remove them in flutter

How can I get random items from a String List and then remove them in flutter,

Also I need to copy the list to reset the system

I would like to know too if its possible to call a variable with the String value from other variable

for example:

String house = 'x';

var listx = ['leo', 'pepe', 'juan', 'pedrito', 'jorgito'];

result = $list$house;

                                                                    thanks!
