Flavors allow building an app for different environments like development and production by configuring variables like API endpoints differently for each flavor. To use flavors, create separate "dev" and "prod" build schemes, duplicate the debug, release, and profile configurations for the dev scheme, and assign the correct configurations to each scheme so the development version points to dev APIs and the production version uses production APIs.

1. How to add flavors
support? - Flutter

2. Why do you need flavors?
Flavors are typically used to build your app for different environments
such as dev and prod.
For eg.
- your development version of the app might want to point to an API
host at dev.api.myapp.com
- and your production version of the app might want to point to
api.myapp.com.
Instead of hardcoding these values into variables and building an app
for every environment manually, the right approach is to use flavors,
and supply these values as build time configurations.

5. Custom Schemes
You need to create two schemes for
two different environments: dev &
prod. Follow the directions below:
● Create Scheme: dev -> Create debug, release and profile configuration for this new
scheme (Project Runner -> Configuration-> Duplicate debug, release and profile
configs for dev scheme)
● Rename existing Runner default scheme to prod.
● Manage scheme -> Assign correct configuration to its corresponding scheme.
