MissingPluginException(No implementation Found for method getDabasesPath on channel com.tekartik.sqf-CodePudding

Hello guys I made simple application use sqflite when I want to insert database it says in console MissingPluginException(No implementation Found for method getDabasesPath on channel com.tekartik.sqflite)

this is code main.dart

import 'dart:async';
import 'package:ass/sqlflite.dart';
import 'package:flutter/material.dart';

void main() async {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Home(),
      title: 'Sqlflite',
    );
  }
}

class Home extends StatefulWidget {
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  SqlDb sqlDb = SqlDb();
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Container(
        child: Column(
          children: <Widget>[
            Center(
              child: MaterialButton(
                color: Theme.of(context).primaryColor,
                child: Text(
                  'InsertData  ',
                  style: TextStyle(color: Colors.white),
                ),
                onPressed: () async {
                  int response = await sqlDb.insertData(
                      "INSERT into 'notes' ('note') VALUES ('note one')");
                  print(response);
                },
              ),
            ),
            Center(
              child: MaterialButton(
                color: Theme.of(context).primaryColor,
                child: Text(
                  'ReadData  ',
                  style: TextStyle(color: Colors.white),
                ),
                onPressed: () async {
                  List<Map> response =
                      await sqlDb.readData("SELECT * FROM notes");
                  print(response);
                },
              ),
            ),
          ],
        ),
      ),
    );
  }
}

and sqlflite.dart

import 'dart:async';
import 'package:sqflite/sqflite.dart';
import 'package:path/path.dart';

class SqlDb {
  static Database? _db;
  Future<Database?> get db async {
    if (_db == null) {
      _db = await initialDb();
      return db;
    } else {
      return _db;
    }
  }

  initialDb() async {
    var databasepath = await getDatabasesPath();
    String path = await join(databasepath, 'wael.db');
    Database mydb = await openDatabase(path,
        onCreate: _onCreate, version: 3, onUpgrade: _onUpgrade);
    return mydb;
  }

  _onUpgrade(Database db, int oldversion, int newversion) async {
    print("upgrade on =============");
  }

  _onCreate(Database db, int version) async {
    await db.execute('''
CREATE TABLE "notes"(
  "id" INTEGER  NOT NULL PRIMARY KEY AUTOINCREMENT ,
  "note" TEXT NOT NULL
)

''');
    print("create DB");
  }

  readData(String sql) async {
    Database? mydb = await db;
    List<Map> response = await mydb!.rawQuery(sql);
    return response;
  }

  insertData(String sql) async {
    Database? mydb = await db;
    int response = await mydb!.rawInsert(sql);
    return response;
  }

  updateData(String sql) async {
    Database? mydb = await db;
    int response = await mydb!.rawUpdate(sql);
    return response;
  }

  deleteData(String sql) async {
    Database? mydb = await db;
    int response = await mydb!.rawDelete(sql);
    return response;
  }
}

it doesn't make any errors in analyzer but when the emulator appears and click on insertdata button it says in console MissingPluginException(No implementation Found for method getDabasesPath on channel com.tekartik.sqflite)
