The lazy is a very handy feature in Kotlin. We don't initialize any object unless we require it. This is quite an optimized approach. A typical case can be binding on a view with an object when required. We initialized a toolbar in HomeActivity to demonstrate the lazy property. There can be many other use cases using it:
val toolbar by lazy { find<Toolbar>(R.id.toolbar) }
A lazy delegated property can only be used with val. Whatever you define inside the block that will get executed only once.
Use it carefully, initializing a heavy object when it is required can affect application response. Do not execute functions doing too much inside the lazy block.
