Should I use type inference?

Very simple question here.

Should I do this?


val re1 = txtRe1.text.toString().toIntOrNull() ?: 0

Or this?


val re1: Int = txtRe1.text.toString().toIntOrNull() ?: 0

Or for example:


val spinner: Spinner = findViewById(R.id.spinner)

or


val spinner = findViewById(R.id.spinner)

Thanks.
