Have you used Flavors in your projects?

In Flutter, Flavors are used to create different configurations of an application, such as for development, testing, and production. This allows having different settings, such as API URLs, icon keys, and other parameters, without changing the main code.

Example of using Flavors:

1. Create different main files, for example, main_dev.dart and main_prod.dart.
2. Specify the appropriate settings in each file.
3. Configure the build in flutter build with the desired flavor.

This helps manage multiple versions of an application from a single codebase.
