Estou criando um aplicativo móvel com o React Native e estou usando o React Navigation para criar um navegador dentro do meu aplicativo. A navegação de reação forneceu-me uma boa maneira de lidar com barras de guias aninhadas dentro de uma gaveta que também está dentro de um Stack Navigator.

O problema é que preciso especificar componentes para poder fornecê-los na barra de guias. Digamos que precisamos buscar algumas categorias em uma API e não sabemos quantas categorias estão dentro dos dados. Além disso, não consegui descobrir que, mesmo se eu tentar buscar dados no início, a configuração do navegador e do redux ocorrerá no início, o que significa que o aplicativo precisa conhecer os componentes desses navegadores de guias. Não consegui descobrir que, mesmo que eu tenha buscado os dados da API, como posso criar vários componentes e parar a configuração do aplicativo.

O código abaixo, apenas demonstra como eu implementei a barra de guias. Esse código funciona no index.js porque, como mencionei anteriormente, o aplicativo precisa conhecer os componentes dentro do Navegador.

const TabStack = TabNavigator({
    Food: { screen: FoodStack},
    Drink : { screen: DrinkStack },
    HealthCare : { screen: SnackProducts },
    Snacks: { screen: SnackStack },
},
    {
        tabBarComponent : props => <CustomTabItems props={props}/>,
        tabBarPosition: 'top',
        animationEnabled : true,
        initialRouteName : 'Food',
        swipeEnabled: true,
        tabBarOptions : {
 
            scrollEnabled : true
        }
})

obrigado
