import {SafeAreaProvider} from 'react-native-safe-area-context';
const tabs: TabsConfigsType = {
    Home: {
        icon: ({ progress }) => /* ICON COMPONENT */

    <NavigationContainer>
      <Tab.Navigator
        tabBar={props => (
          <AnimatedTabBar tabs={tabs} {...props} />
        )}
      >
        <Tab.Screen
          name="Home"
          component={HomeScreen}
        />
        <Tab.Screen
          name="Profile"

        />

import React from 'react';
import {createAppContainer} from 'react-navigation';
import {createBottomTabNavigator} from 'react-navigation-tabs';
import {createStackNavigator} from 'react-navigation-stack';
import {SafeAreaProvider} from 'react-native-safe-area-context';
import AnimatedTabBar, {TabsConfigsType} from 'curved-bottom-navigation-bar';

const tabs: TabsConfigsType = {
    Home: {
        icon: ({ progress }) => /* ICON COMPONENT */

const TabNavigator = createBottomTabNavigator(
  {
    Home: HomeScreen,
    Profile: ProfileScreen,
  },
  {
    tabBarComponent: props => <AnimatedTabBar tabs={tabs} {...props} />,
  },
);

const AppContainer = createAppContainer(TabNavigator);

export default () => (
  <SafeAreaProvider>
    <AppContainer />
  </SafeAreaProvider>
);

import React from 'react';
import Animated from 'react-native-reanimated';


interface AnimatedIconProps {
  progress: Animated.Node<number>; // Reanimated - 0 is not Active, 1 is Active
}

const AnimatedIcon = ({ progress }: AnimatedIconProps) => {
  return (
   /* DO SOME THING */
  );
};

export default AnimatedIcon;
