    Example usage of all the component can be seen using this file

    Required Props

    SNO Prop Type Default Required description
    1. inputFields Array Nope Yes Click here
    2. onButtonClick Async function Nope Yes Passed function receives index of the element in array, key associated with it and the complete payload, This is triggered after user have clicked on the Next button, and before the iteration happens, you can throw errors here to prevent from incrementing to the text state

    This is how error handling is done behind the scene: if (error.message) setErrorData({status: true, message: error.message})

    Optional Props

    Important Props are highlighted.

    4. backgroundViewColor string 'white' No background for the view of your form

    Note

    1. for stylesheet object type props. you need to pass props like this

    })
    

    and then pass styles.someStyle in props

    1. For stylesheet object, Default None does not mean that element won't have any styles; the props provided by the user would override the default styling.
