init_in_widget.dart

class _MyAppState extends State<MyApp> {

  Database _database;

  @override
  void initState() {
    super.initState();

    asyncInitState();
  }

  void asyncInitState() async {
    var databasesPath = await getDatabasesPath();
    var path = join(databasesPath, 'example.db');

    setState(() {
      this._database = await openDatabase(path, version: 1, onCreate: (db, version) async {
        await db.execute('''CREATE TABLE MyTable (
              id INTEGER PRIMARY KEY, 
              name TEXT)''');
      });
    });
  }
  
  @override

      home: this._database == null ?
