@Shawn may I know what is the correct or best way of doing it?

What does TextUtils.isEmpty(email) do? Is it the same as string.isEmpty()?
If yes, then you can write

buttonRegister.isEnabled = email.isNotEmpty() && password.isNotEmpty() && confirmPassword.isNotEmpty()

[gildor]

I suppose TextUtils.isEmpty is from Android android.text.TextUtils, so it’s like isNullOrEmpty(), but for non-null variables in Kotlin it can be replaced with isNotEmpty()

[Ayden]

@Pavlo Liapota TextUtils is a package in Android.

[gildor]

so instead you can use isEmpty(), isNotEmpty() or isNullOrEmpty(), depending on your use case and types

[digitalsanctum]

how about: buttonRegister.isEnabled = listOf(email, password, confirmPassword).none { it.isNullOrEmpty() } ?

@digitalsanctum that’s real fancy. I like that.
