Why do I get an UninitializedPropertyAccessException? Android Kotlin

So I'm trying to send a text data from text entered in edit text through another activity with intent. I'm trying to send the text data from HomeActivity to SearchResultActivity. However, when I clicked the button that calls the startActivity(intent), my application forced closed and I get this exception:

I'm quite confused what I did wrong here. This is my code for the home activity. I have already initialized the binding in the onCreate function but why is it still saying that its uninitialized?

 override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val activityHomeBinding = ActivityHomeBinding.inflate(layoutInflater)
    setContentView(activityHomeBinding.root)
    activityHomeBinding.btnSearch.setOnClickListener(this)
}

    override fun onClick(v: View?) {
    when (v?.id){
        R.id.btn_search -> {
            val searchText = activityHomeBinding.editTextSearch.text.toString().trim()
            if (searchText == null){
                activityHomeBinding.editTextSearch.error = "Field cannot be empty"
            } else {
                val intent = Intent(this@HomeActivity, SearchResultActivity::class.java)
                intent.putExtra(SearchResultActivity.EXTRA_SEARCH,searchText)
                startActivity(intent)
            }
        }
    }

And this is the code inside my SearchResultActivity:

private lateinit var searchResultActivity: ActivitySearchResultBinding

companion object {
    const val EXTRA_SEARCH = "extra_search"
}

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    searchResultActivity = ActivitySearchResultBinding.inflate(layoutInflater)
    setContentView(searchResultActivity.root)

    searchResultActivity.testIntent.text = intent.getStringExtra(EXTRA_SEARCH)
}

The error message points that on line 39 of your HomeActivity class, you're pointing at an uninitialized property. This is because you have defined 2 activityHomeBindings with different scopes

class HomeActivity : AppCompatActivity(), View.OnClickListener {
    
    ...

    lateinit var activityHomeBinding: ActivityHomeBinding <-- 1st one, globally scoped

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val activityHomeBinding = ActivityHomeBinding.inflate(layoutInflater) <-- 2nd one, function-scoped (to onCreate)
        setContentView(activityHomeBinding.root)
        activityHomeBinding.btnSearch.setOnClickListener(this)
    }

    override fun onClick(v: View?) {
        when (v?.id){
            R.id.btn_search -> {
                val searchText = activityHomeBinding.editTextSearch.text.toString().trim() <-- this points at 1st one, (i.e. globally scoped)
                if (searchText == null){
                    activityHomeBinding.editTextSearch.error = "Field cannot be empty"
                } 

                ...
            }
        }
    }
}

The solution is to simply remove val from the line where you're inflating the binding. This way, instead of creating a new variable, you're assigning the inflated binding to globally scoped lateinit var activityHomeBinding which then can be used by your onClick callback.

So make the change from

override fun onCreate(savedInstanceState: Bundle?) {
    ...
    val activityHomeBinding = ActivityHomeBinding.inflate(layoutInflater)
    ...
}

to

override fun onCreate(savedInstanceState: Bundle?) {
    ...
    activityHomeBinding = ActivityHomeBinding.inflate(layoutInflater)
    ...
}
