With the help of this library , handling fragment will be Piece of cake for you. This library helps you to keeps history of previous tabs so that when the current tab's stack is exhausted the system back button will navigate to the previously selected tab. If you want to switch between fragments with botttomnavigation view, without losing fragments state and along with if you want to maintain backstack of fragments. Then this library is for you.

<dependency>
   <groupId>com.github.GitEliteNovice</groupId>
    <artifactId>BackStack_BottomNavigation</artifactId>
    <version>v1.01</version>
</dependency>

For implementation

Make instance of Library like this

 fragmentStackNew= com.aryan.bottomnavlibrary.FragmentStackNew.Builder()
                     .bottomMaxCount(3)                      // bottom tabs you have 
                     .conatiner_id(R.id.frag_container)     // container id when you want add fragments	  	         
		 .lastFragmentToStay(HomeFragment::class.java).   // last fragment to reach when all fragment removed from backstack
                     .build(this)            

 fragmentStackNew.updateFrag(HomeFragment::class.java,null).       // add fragment to show 

If you want to send extra data to fragment, you can do something like this

 bundle= Bundle()
 bundle.putString("Name","Aryan")
 bundle.putInt("Age",27)
   	    
 fragmentStackNew.updateFrag(HomeFragment::class.java,bundle).    // send extra data to fragment

If you want to handle state even when the activity kills by andoid os

 override fun onSaveInstanceState(outState: Bundle) {
     var outStatenew=  fragmentStackNew.setOutstatebundle(outState).    // add oustate bundle to library instance
      super.onSaveInstanceState(outStatenew)
   }

Inside onCreate method, do something like this

if (savedInstanceState==null){

 fragmentStackNew= com.aryan.bottomnavlibrary.FragmentStackNew.Builder()
                       .bottomMaxCount(3)
                       .conatiner_id(R.id.frag_container).
                        lastFragmentToStay(HomeFragment::class.java)
                         .build(this)

       bundle.putString("Name","Aryan")
       bundle.putInt("Age",27)
  
   fragmentStackNew.updateFrag(HomeFragment::class.java,bundle)
  
   }
else
  {

fragmentStackNew= com.aryan.bottomnavlibrary.FragmentStackNew.Builder()
    .bottomMaxCount(3)
    .conatiner_id(R.id.frag_container).
    lastFragmentToStay(HomeFragment::class.java)
    .build(this)
         
fragmentStackNew.savedInstanceState(savedInstanceState)

   }
