how to flutter convert maps to String

hello i get data in sqlite code :

getuserIDPW(String email) async{
    final db = await database;
    var res = await db.query("person",columns: ['email', 'password'] ,where: "email = ?", whereArgs: [email]);
    return res.isNotEmpty? res : Null;
  }

code :

var useridpw = await DBHelper().getuserIDPW(_email);
        print(useridpw);

That's how I got the result of [{email: kmail, password: 123123}]

But i want String like this : var tmpEmail = 'kmail';

How to get String in map ?

I'd be grateful if someone would help me.

You can use like below code if you want to get specific String :-

Future<String> getuserIDPW(String email) async{
      final db = await database;
      var res = await db.query("person",columns: ['email', 'password'] ,where: "email = ?", whereArgs: [email]);
      return res.isNotEmpty? res[0][yourKey like 'email' OR 'password'] : Null;
    }

u can get you email by doing this :

first u have a list so u should map it 

var email ; 
useridpw.map((e) {
email = e['email'];
}).toList()
