How to check the state of a Dirty Form in React?

Question

React

Imagine there is a Form.js component

// Form.js
<form>
  <input type="text" value="" />
</form>

And the main App.js component in which our forms are imported.

// App.js
<Form />

What are the ways to check this form for change?
Some kind of global method is needed. For example, it is possible that we will have a Save button on the page, which we need to disable if the form is not touched.

// Footer.js
<button onClick={save}>Save</button>.

In general, in what ways on the bare React check the form for Dirty (change).
Yes, coding in React with Angular's thoughts is not an option ...
Here, on Angular, there was a form.$dirty method that returns true or false. But here's the trouble with React)
