Foundations of React Native
Using the Switch Component for Toggles
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?
Binary Selection :
Useful for scenarios where you need users to make a binary choice;
Commonly used for settings, preferences, or toggling certain features.
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 itsvalue
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.
