Dart 2.17 has warning when using code snipplet

Question

I just update dart sdk to 2.17 and when I use snipplet (in VScode) to auto generate code for Stateless/Stateful it auto import these two package.

But it tell me warning Don't import implementation files from another package. Is this normal?

Answer 1

Why are you importing implementation files from Flutter? If you have Flutter setup right you do not need to import anything like this.

Answer 2

You're importing files from a package's src directory. That is not normal. You're directly importing a package's internal, private files.

The analysis warning tells you the name of the warning (implementation_imports), and your IDE should allow you to click on it to get more details:

Instead use:

import 'package:flutter/foundation.dart';
import 'package:flutter/widgets.dart';
