So many times using findViewById

sythetic depricate ho gai to ek ek karke sabke liye find view by id ka use karna padraha hai yaha pr 9 buttons the sabki id lena padegi iske liye koi aur alternative nahi hai kya

@harshitsoni you can still use synthetic by adding
apply plugin: 'kotlin-android-extensions'
at the top of build.gradle (app)

incase you don’t want to use synthetic as it is deprecated. I suggest using ViewBinding or Databinding.
this requires adding a bit of code in every fragment or activity.

To use ViewBinding you can have a look at its setup instructions if you face any issues do let me know
