Je construis donc un formulaire dans React en utilisant formik. J'ai créé un composant TextInput qui contient un champ de saisie avec quelques modifications. Lorsque j'utilise changeHandler, il devrait mettre à jour la valeur que j'ai saisie, mais ce n'est pas le cas. Je me demande si je devrais apporter des modifications au composant textInput.

Par exemple
Pensez-y de cette façon,
