Theory

The Switch component in React Native is used to toggle between two states - typically representing an "on/off" or "true/false" selection. It provides users with a visual indicator of the current state and allows them to change it with a simple tap.

Why Do We Need It?

1. Binary Selection:

   • Useful for scenarios where you need users to make a binary choice;

   • Commonly used for settings, preferences, or toggling certain features.

2. User-Friendly:

   • Provides a simple and intuitive interface for toggling between states;

   • Offers a visual cue of the current state, enhancing user experience.

How to Work with Switch

• The Switch component is controlled through its value prop, which determines whether it is in the "on" or "off" state;

• We can use the onValueChange prop to specify a callback function that will be called when the user toggles the switch.
