Usage

import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import AnimatedTabBar, {TabsConfigsType} from 'curved-bottom-navigation-bar';
import {SafeAreaProvider} from 'react-native-safe-area-context';
const tabs: TabsConfigsType = {
    Home: {
        icon: ({ progress, focused }) => /* Icon Component */,
        renderTitle: ({ progress, title }) => /* Custom reanimated Component */
    },
    Profile: {
        icon: ({ progress, focused }) => /* Icon Component */,
        renderTitle: ({ progress, title }) => /* Custom reanimated Component */
    },
}

const Tab = createBottomTabNavigator();

export default function App() {
  return (
  <SafeAreaProvider>
    <NavigationContainer>
      <Tab.Navigator
        tabBar={props => (
          <AnimatedTabBar tabs={tabs} {...props} />
        )}
      >
        <Tab.Screen
          name="Home"
          component={HomeScreen}
        />
        <Tab.Screen
          name="Profile"
          component={ProfileScreen}
        />
      </Tab.Navigator>
    </NavigationContainer>
  </SafeAreaProvider>
  )
}

Animated Icon

In order to animate the tab icon color, you will need to use the provded prop color that will be provided to the icon.

This example below should explain it better:

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


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

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

export default AnimatedIcon;

Animated Title

Custom title value for tabbar

This example below should explain it better:

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


interface AnimatedTitleProps {
  progress: Animated.SharedValue<number>; // Reanimated - 0 is not Active, 1 is Active
  title:string;
}

const AnimatedTitle = ({ progress, title }: AnimatedTitleProps) => {
  return (
   /* DO SOME THING */
  );
};

export default AnimatedTitle;
