Kotlin equivalent for checking if not null

Question

Can below snippet be written in shorter form in Kotlin using ! or ? operators:

val acct: GoogleSignInAccount?  = result.signInAccount
if (acct != null && acct.displayName != null)
    MagicToast.showSuccess(this, "Account Name: " + acct.displayName)

you can just check the documentation for these kind of questions. It's all explained very well — Tim, Nov 05 '18 at 14:38

acct?.displayName?.let {
    MagicToast.showSuccess(this, "Account Name: $it")
}

Depending on your use case acct might be replaced with result.signInAccount.
