Avoid `print` calls in production code. (Documentation)

It is because of the flutter_lints package which is implicitly added to new projects created after Flutter 2.3.0.

You can use any of the following solutions.

1. To remove the warning in that single line:

   // ignore: avoid_print
   print('Hello World');
   

2. To remove the warning in that file

   // ignore_for_file: avoid_print
   print('Hello World');
   

3. To remove the warning from the whole project.

   Open analysis_options.yaml file and add this linter rule:

   include: package:flutter_lints/flutter.yaml
   
   linter:
     rules:
       avoid_print: false
   

Why not debugPrint or log?

Although you can also use debugPrint, or log (from dart:developer), but there are a few reasons why I don’t like them.

1. They both work only in Flutter apps (not Dart apps)
2. You’ll have to manually import a library for them to work (importing is such a pain unless imports on fly is implemented in IDE)
3. They accept only a String as an argument, unlike print which accepts an Object? (everything)
