I am trying some react native code.
Added props for my component based on the instructions given in this blog.
End up in the error, Can't find variable: PropTypes Found the same question in github but it was closed without any answers
Couldn't get any clues.

Props are required in TypeScriptisRequired explicitly.
PropTypes are a good first line defense when it comes to debugging your apps. But before getting into detail about PropTypes, we have to understand the concept of props. Props are the read-only properties that are shared between components to give the unidirectional flow of React a dynamic touch.
Typescript and PropTypes serve different purposes. Typescript validates types at compile time, whereas PropTypes are checked at runtime. Typescript is useful when you are writing code: it will warn you if you pass an argument of the wrong type to your React components, give you autocomplete for function calls, etc.
In this example, we are using a class component, but the same functionality could also be applied to function components, or components created by React.memo or React.forwardRef . PropTypes exports a range of validators that can be used to make sure the data you receive is valid.
You need to do install prop-types with npm install --save prop-types or yarn add prop-types and then add this to your code:
import PropTypes from 'prop-types';
