State Update on Unmounted Component

[dustinlacewell]

When using React Router, when ink-text-input become unmounted it throws the following error:

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.
    in TextInput (created by Test)
    in ink-box (created by Box)
    in Box (created by Test)
    in Test (created by Start)

    in Box (created by Start)
    in ink-box (created by Box)
    in Box (created by Fullscreen)

Tried reproducing it with this, but didn't see that error:

const React = require('react')
const {Box, Text, render} = require('ink')
const TextInput = require('.').default

const Example = () => {
	const [show, setShow] = React.useState(true)
	const [value, setValue] = React.useState('')

	const submit = React.useCallback(() => {
		setShow(false)
	}, [])

	return <Box>
		{show && <TextInput value={value} onChange={setValue} onSubmit={submit}/>}
		{!show && <Text>Got the input</Text>}
	</Box>
}

render(<Example/>)
