Estou usando a câmera react-native para captura de vídeo. Estou construindo algo como histórias do snapchat em que, no momento em que você captura um vídeo, ele o leva para a tela de visualização do vídeo, onde você pode editar. Ao pressionar o botão Iniciar enquanto a tela videoCapturing retorna o caminho do vídeo, mas ao pressionar o botão Parar, ele retorna um erro ao mesmo tempo em que o vídeo é armazenado no armazenamento do dispositivo. Eu publiquei tanto a tela de videocaptura quanto o erro que estou pressionando o botão de parada. Código anexado à tela do VideoCapture.
