+Initialization of BottomNavigationView
+
+```
+ private lateinit var bottomNavigationView: BottomNavigationView
+
+ bottomNavigationView = findViewById(R.id.bottomView)
+```
+
+#### Add tab item in BottomNavigationView
+When you want to show only icon and title:
+
First icon will be for unselected state and second icon will be used for selected state
+
+```
+ bottomNavigationView.addChild(R.drawable.ic_chat_icon,R.drawable.ic_chat_icon, getString(R.string.title_chats))
+ bottomNavigationView.addChild(R.drawable.ic_contacts_icon,R.drawable.ic_contacts_icon, getString(R.string.title_contacts))
+ bottomNavigationView.addChild(R.drawable.ic_man_user_icon,R.drawable.ic_man_user_icon, getString(R.string.title_account))
+```
+When you want to show only icon:
+
Add only icon and rest should be null
+````
+ bottomNavigationView.addChild(R.drawable.ic_chat_icon, null, null)
+ bottomNavigationView.addChild(R.drawable.ic_contacts_icon, null, null)
+ bottomNavigationView.addChild(R.drawable.ic_man_user_icon, null, null)
+````
+When you want to show only name:
+
Add only name and rest should be null
+````
+ bottomNavigationView.addChild(null, null, getString(R.string.title_chats))
+ bottomNavigationView.addChild(null, null, getString(R.string.title_contacts))
+ bottomNavigationView.addChild(null, null, getString(R.string.title_account))
+````
+When you pass null for second icon and add first icon as well title
+then icon will remain same after click
+````
+ bottomNavigationView.addChild(R.drawable.ic_chat_icon, null, getString(R.string.title_chats))
+````
+#### Add Listener
+````
+ bottomNavigationView.initItemListener(this)
+
+ override fun bottomNavigationViewItemClickListener(position: Int) {
+ if (position == 0) textTitle.text = getString(R.string.title_chats)
+ if (position == 1) textTitle.text = getString(R.string.title_contacts)
+ if (position == 2) textTitle.text = getString(R.string.title_account)
+ // Toast.makeText(applicationContext, "" + position, Toast.LENGTH_SHORT).show()
+ }
+````
+
+##### Change Font of tab item
+
+````
+ bottomNavigationView.updateFont("fonts/roboto_medium.ttf")
+````
+##### Add Badge in tab
+Index: example pass 0 for first item and count is for badge quantity
+````
+ bottomNavigationView.setBadge(index, count)
+````
+
+###### Limitations
+if you add more item(more then 5,6), some icon or text can be have size/cut/invisible issues
