I have an application in Flutter,and I’m trying to convert my Password to MD5 on the login screen, I found some other methods but none served me.
I’m trying to use final md5 = new MD5._() to convert final String password;, but without success.
Would there be some other way to encrypt the String using the package Crypto flutter?

You can use the lib Crypto. It has support for hash algorithms:
Just add in your pubspec.yaml:
crypto: ^2.0.6
Import the packages:
import 'dart:convert';
import 'package:crypto/crypto.dart';
And now the code:
String textToMd5 (String text) {
return md5.convert(utf8.encode(text)).toString();
}
The md5.convert receives an int list, so we need to encode the string first with the utf8.encode.
In the lib link you find examples with other hashs.
Thank you very much Julio, it worked correctly so. I just called the textToMd5 in my Map toMap() {
 var map = new Map<String, dynamic>();
 map["password"] = textToMd5(password);
 return map;
 }
Show! Just a hint, don’t use the 'new' reserved word for creating the objects, from Dart 2 it has become optional, and it is now a 'default' of the community not to use it. Facilitates reading of code.
Great, thanks for the tip, I’ll put in practice from now on.
