React Evergreen is a popular front-end library with a set of React components for building beautiful products as this library is flexible, sensible defaults, and User friendly. Switch Component allows the user to toggle the state of a single setting on or off. We can use the following approach in ReactJS to use the Evergreen Switch Component.

Switch Props:

• id: It is used to denote the id attribute of the radio.
• name: It is used to define the name attribute of the radio.
• value: It is used to denote the value attribute of the radio.
• height: It is used to define the height of the switch.
• checked: The switch is checked when this is set to true.
• onChange: It is a function that is called when the state changes.
• disabled: The switch is disabled when this is set to true.
• isInvalid: The switch is invalid when this is set to true.
• appearance: It is used for the appearance of the checkbox.
• hasCheckIcon: The switch has a check icon when this is set to true.
• defaultChecked: The switch is true by default when this is set to true.
