Android studio request permissions code is wrong pls hlp

Question

I am working with the Kotlin language in android studio. I am requesting permission to access the gallery and I am writing this when I use the "if-else" structure to query the permission and there is a dash above the requestPermissions statement. how do we solve this.

activity?.let {
        if (ContextCompat.checkSelfPermission(requireActivity().applicationContext,Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {
            requestPermissions(arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE), 1)

The new approach to request permissions is to use launchers. You have to create the launchers before setContent().

At the very top before onCreate, create a launcher property:

val storagePermissionLauncher = registerForActivityResult(ActivityResultContracts.startActivityForResult())
{ result->
  if(result.RESULT_CODE == RESULT_OK) {
    //permission granted
    doSomething()
  }
}

When you have to do something that requires a permission. You have to check if you have the permission:

if(ContextCompat.checkSelfPermission(context, android.Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED){
  //you have the permission
  doSomething()
}else{
//You don't have the permission, ask for it.
  storagePermissionLauncher.launch(android.Manifest.permission.READ_EXTERNAL_STORAGE) 
}
