What is the easiest way to save a variable using shared preferences in kotlin?

Question

What is the easiest way to save and load this variable using shared preferences (kotlin)?

var score = 12.5

And yes the score variable is a double not int.

No it doesn't answer my question because it's not detailed and they are using java not kotlin, i want to get an answer on how you can do that using kotlin. — Adel gamer, Oct 30 '20 at 15:57

score -1 · Answer 1 · answered Oct 30 '20 at 16:45

-1

To put inside:

with(PreferenceManager.getDefaultSharedPreferences(this).edit()){
 putDouble("SCORE",score)
 apply()
}

To retrieve:

val score = PreferenceManager.getDefaultSharedPreferences(this).getDouble("SCORE",0.0)
