Customizing Tab Navigation in React using TypeScript Parameters

Currently, my project involves developing projects using Typescript in conjunction with the React Native library. One specific task I am working on is creating a Custom Tab Bar and the necessary parameters include state, descriptors, and navigation. When defining the type for this particular scenario, what specifics should I consider?

import { View, Text, TouchableOpacity } from 'react-native';

function MyTabBar({ state, descriptors, navigation }) {
  const focusedOptions = descriptors[state.routes[state.index].key].options;

  if (focusedOptions.tabBarVisible === false) {
    return null;
  }

  return (
    <View style={{ flexDirection: 'row' }}>
      {state.routes.map((route, index) => {
        const { options } = descriptors[route.key];
        const label =
          options.tabBarLabel !== undefined
            ? options.tabBarLabel
            : options.title !== undefined
            ? options.title
            : route.name;
........

Answer №1

  • Top Tab Navigator = "MaterialTopTabBarProps"
  • Bottom Tab Bar = "BottomTabBarProps"
import { BottomTabBarProps } from '@navigation/bottom-tabs';  

import { MaterialTopTabBarProps } from '@navigation/material-top-tabs';

Answer №2

TabBarProps interface details:
state: TabNavigationState<ParamListBase>;
descriptors: BottomTabDescriptorMap;
navigation: NavigationHelpers<ParamListBase, BottomTabNavigationEventMap>;

MyTabBar component function with passed props:
const MyTabBar = ({ state, descriptors, navigation }: TabBarProps) => {
...
