is attempting to registerForActivityResult after being created. Fragments must call registerForActivityResult() before they are created (i.e. initialization, onAttach(), or onCreate())

fragment:1.3.0-alpha08 之后，需要在Fragment注册registerForActivityResult时，注册体需要写在onAttach() 或 onCreate()里

举个例子，AFragment需要跳转到BActivity，并且获取到BActivity的回调数据，需要这么写 

class AFragment : Fragment() {
    private lateinit var binding:FragmentABinding
    private lateinit var startActivitylaunch: ActivityResultLauncher<Intent>

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)        
        
        startActivitylaunch = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
            //获取到BActivity回传的数据
            val resultCode = it.resultCode
            val data = it.data
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        binding = FragmentABinding.inflate(inflater,container,false)
        return binding.root
    }
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        binding.btn1.setOnClickListener {
            //打开ActivityB
            startActivitylaunch.launch(Intent(requireContext(),BActivity::class.java))
        }
    }
}
