I treated it differently. Following a tutorial, I separated the checkbox with a function and where it renders only the status. It was like this:
this.setState({
checked: !this.state.checked
})
alert('agora está ' + !this.state.checked)
} ```
<View style={styles.bottomContainer}>
<Text style={[styles.bottomContainerText, { color: themes[theme].auxiliaryText }]}>
<CheckBox
value={this.state.checked}
onValueChange={() => this.checkBoxTest()}
/>
{'Li e concordo com os Termos de uso*'}
</Text>
<Text style={[styles.bottomContainerTextBold, { color: themes[theme].auxiliaryText }]}>
{'* Concordo que os dados pessoais fornecidos acima serão utilizados para envio de conteúdo informativo, analítico e publicitário e para contato por parceiros DVinvest, nos termos da Lei Geral de Proteção de Dados.'}
</Text>
</View>
Agora ele retorna um alert com o status. True = marcado e false = desmarcado. Preciso tratar ele para: quando for true eu tenho a mensagem OK e false eu mando um alert pra ele marcar.
Code does not have a minimal example, did not understand the part of the error or warning message (which in my view is much better, error is always problematic) and which is your doubt?

I have a box to be marked by the user which by default comes as true (already checked). I need when he clears this box, that he has an error message that this box necessarily needs to be messed up for him to follow.

in a few code would be:
{!this.state.checked && 'Mensagem de problema'}This shows a warning message!– novic
