Usage Example

import React, { useMemo, useState } from 'react';
import { View } from 'react-native';
import { ReanimatedTabView, SceneMap } from 'react-native-reanimated-tab-view';

export const TabView = () => {
  const [index, setIndex] = useState(0);
  const renderScene = SceneMap({
    first: <View style={{ flex: 1, backgroundColor: 'blue' }} />,
    second: <View style={{ flex: 1, backgroundColor: 'yellow' }} />,
    third: <View style={{ flex: 1, backgroundColor: 'red' }} />,
  });

  const routes = useMemo(
    () => [
      { key: 'first', title: 'Posts' },
      { key: 'second', title: 'Reels' },
      { key: 'third', title: 'Tagged' },
    ],
    []
  );
  return (
    <SafeAreaView style={{ flex: 1 }}>
      <ReanimatedTabView
        navigationState={{ index, routes }}
        renderScene={renderScene}
