How can I solve these errors

Question

import 'dart:html';

import 'package:flutter/material.dart';


class SearchScreen extends StatefulWidget {
  const SearchScreen({Key? key}) : super(key: key);

  @override
  _SearchScreenState createState() => _SearchScreenState();
}

class _SearchScreenState extends State<SearchScreen> {
  TextEditingController userCurrentLocationTextEditingContrpller = TextEditingController();
  TextEditingController photoShootLocationTextEditingControler = TextEditingController();

  @override
  Widget build(BuildContext context) {

    
    String placeAddress = Provider.of<AppData>(context).userCurrentLocation.placeName ?? "";
    userCurrentLocationTextEditingContrpller.text = placeAddress;
}

But I get these errors:

Error: 'AppData' isn't a type.
    String placeAddress = Provider.of<AppData>(context).userCurrentLocation.placeName ?? "";

Error: The getter 'Provider' isn't defined for the class '_SearchScreenState'.

Try correcting the name to the name of an existing getter, or defining a getter or field named 'Provider'.
    String placeAddress = Provider.of<AppData>(context).userCurrentLocation.placeName ?? "";

Seems like you forgot to add imports to the file. For Provider try adding something like

import 'package:provider/provider.dart';

Than you should also import your AppData in the file. I can't really guess what this import will look like, but your IDE might suggest it to you. For example in VScode if you click on the AppData - a lightbulb will appear and upon clicking it, it will suggest to import a package with AppData you are looking for
