// utils/Const.kt

const val DEFAULT_TIME_MILLIS = 3000L // for default timer in ms

const val DEFAULT_PAGER_SIZE = 3 // for viewpager ui const

DEFAULT_TIME

even refer to?

to use in everywhere when I try to construct an object time with default value

DEFAULT_TIME_MILLIS

, is this overkill?

That suggests every default time is the same
