Answer 1

This is not really an error, it's just an info message. This message comes from the flutter_lints package that tells you the recommended best practices.

You can learn more about const in Dart from here .

If you want to disable linting then go to the analysis_options.yaml file (present inside the root directory of your Flutter project) and comment out the line:

include: package:flutter_lints/flutter.yaml

But keep in mind this is not recommended.

Answer 2

To prefer const with constant constructors

Go to analaysis_options.yaml file in your Flutter project folder, then under rules title type Prefer_const_constructors: false Prefer_const_literals_to_create_immutables: false Then save it Tip: Type it not copy it
