Commencez par le reproducteur secure-text-entry-flicker lié et exécutez-le avec yarn ios sur un simulateur ou un appareil iOS. Vérifiez le scintillement lorsque secureTextEntry utilise une police personnalisée et qu’un caractère est saisi puis supprimé, en comparant les nouveaux et anciens renderers ; le travail est terminé lorsque le texte ne scintille plus dans les deux cas.
