In this article, we will see how to create buttons in react-native, their syntax, and different types of buttons available in react native. Creating a Button in react native is very simple. First, we have to import the button component from React Native.

const Test = () => {
            // Define Button property
export default Test

On Click of this button, its state is changed and after another click, it regains its original state. This state change function is achieved by click event of the button. To create a toggle we need to set isToggle property to true.
