The name 'Key' is defined in the libraries 'package:encrypt/encrypt.dart' and 'package:flutter/src/foundation/key.dart'. about encrypt

[leocavalcante]

You have a naming conflict, two libraries are exporting a symbol named Key.
You can solve this by adding an alias like:

import 'package:encrypt/encrypt.dart' as encrypt;

Then using the aliased version for every symbol:

final key = encrypt.Key.fromUtf8()
final iv = encrypt.IV.fromUtf8()
final encrypted = encrypt.Encrypter()

You can also alternatively hide the Key, if it isn't in use, exported by Flutter, like:

import 'package:flutter/material.dart' hide Key;
