+Can be used for logging different details. All methods are static thus no instance of Console is required. Console.info() method will print info in blue color font, Console.success() method will print log in green color font, Console.warning() method will print log in yellow color font, and Console.danger() method will print log in red color font.

+### How to create a new environment:
+
+Go to `lib/env.dart`, find `envConfigs` variable and add configuration for the environment you want to create. example: for `testing` environment add `'testing'` key and value. And in commands pass your environment name
+```
+// for example if environment name is testing then
