Quick Start

import { MotionifyProvider } from "react-native-motionify";

export default function App() {
  return (
    <MotionifyProvider threshold={8} supportIdle={false}>
      <YourApp />
    </MotionifyProvider>
  );
}

import { ScrollView, Text, View } from "react-native";
import { useMotionify } from "react-native-motionify";

function Screen() {
  const { onScroll, direction } = useMotionify();
  return (
    <ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      <Text>Direction: {direction}</Text>
      <View style={{ height: 2000 }} />
    </ScrollView>
  );
}

import { MotionifyBottomTab } from "react-native-motionify";

function AppShell() {
  return (
    <>
      <Screen />
      <MotionifyBottomTab hideOn="down" translateRange={{ from: 0, to: 80 }}>
        <TabBar />
      </MotionifyBottomTab>
    </>
  );
}

Important: wire onScroll in every scrollable screen

Any screen that participates in motionify behavior must attach the onScroll from useMotionify() to its ScrollView/FlatList/SectionList and set scrollEventThrottle={16}.

// ScrollView example
const { onScroll } = useMotionify();

<ScrollView onScroll={onScroll} scrollEventThrottle={16} />;

// FlatList example
const { onScroll } = useMotionify();

<FlatList
  data={items}
  keyExtractor={(it) => it.id}
  renderItem={renderItem}
  onScroll={onScroll}
  scrollEventThrottle={16}
/>;

// FlashList (shopify/flash-list) example
import { FlashList } from "@shopify/flash-list";
const { onScroll } = useMotionify();

<FlashList
  data={items}
  renderItem={renderItem}
  estimatedItemSize={72}
  onScroll={onScroll}
  scrollEventThrottle={16}
/>;

// LegendList example
import { LegendList } from "legendapp-ui";
const { onScroll } = useMotionify();

<LegendList
  data={items}
  renderItem={renderItem}
  onScroll={onScroll}
  scrollEventThrottle={16}
/>;

Normal Screen (no bottom tab)

Use this when you only need views to react to scroll (e.g., headers, FABs, content blocks).

import { ScrollView } from "react-native";
import {
  MotionifyProvider,
  useMotionify,
  MotionifyView,
} from "react-native-motionify";

function Screen() {
  const { onScroll } = useMotionify();
  return (
    <ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      {/* content */}
      <MotionifyView
        animatedY
        hideOn="down"
        translateRange={{ from: 0, to: 60 }}
      >
        <FAB />
      </MotionifyView>
    </ScrollView>
  );
}

export default function App() {
  return (
    <MotionifyProvider>
      <Screen />
    </MotionifyProvider>
  );
}

Note: Attach onScroll only once per scrollable container. Child motionify components consume context automatically.

Bottom Tab Behavior

Use this when you want a bottom tab to hide/show with scroll.

import {
  MotionifyProvider,
  MotionifyBottomTab,
  useMotionify,
} from "react-native-motionify";

function Screen() {
  const { onScroll } = useMotionify();
  return (
    <ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      {/* content */}
    </ScrollView>
  );
}

function AppShell() {
  return (
    <>
      <Screen />
      <MotionifyBottomTab hideOn="down" translateRange={{ from: 0, to: 80 }}>
        <TabBar />
      </MotionifyBottomTab>
    </>
  );
}

export default function App() {
  return (
    <MotionifyProvider>
      <AppShell />
    </MotionifyProvider>
  );
}

Notes:

Ensure each screen that should control the tab wires onScroll.
Use exclude and currentId on MotionifyBottomTab to keep the tab visible on specific routes.
Use tabBar.show() when navigating programmatically to ensure tab bar is visible.

API (Essential)

Provider

<MotionifyProvider threshold={8} supportIdle={false}>

threshold: number — pixels to switch direction
supportIdle: boolean — emit idle after inactivity

Hook

useMotionify(config?)

Returns:

scrollY: SharedValue
direction: 'up' | 'down' | 'idle'
directionShared: SharedValue<'up' | 'down' | 'idle'>
isScrolling: boolean
onScroll: Scroll handler for ScrollView/FlatList
setThreshold(threshold)
setSupportIdle(enabled)
tabBar: Tab bar visibility controls (see below)

Optional config: { threshold?: number; supportIdle?: boolean }

Tab Bar Controls

Use tabBar object from useMotionify() to programmatically control tab bar visibility:

const { tabBar } = useMotionify();

// Show tab bar programmatically
tabBar.show();

// Hide tab bar programmatically
tabBar.hide();

// Reset to default scroll-based behavior
tabBar.reset();

Use case: When navigating between tabs programmatically (e.g., from a CTA button), the tab bar may remain hidden. Call tabBar.show() to ensure it appears:

function HomeScreen() {
  const { onScroll, tabBar } = useMotionify();
  const navigation = useNavigation();

  const goToRewards = () => {
    // Show tab bar before navigating
    tabBar.show();
    navigation.navigate('Rewards');
  };

  return (
    <ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      {/* content */}
      <Button title="Go to Rewards" onPress={goToRewards} />
    </ScrollView>
  );
}

Components

<MotionifyView>
- Quick direction-based animations
- Props: animatedY?, fadeScale?, customEffects?, hideOn='down'|'up', translateRange={from,to}, animationDuration, supportIdle, easing

- Props: interpolations, value?, customAnimatedStyle?
<MotionifyBottomTab>
- Hide/show on scroll
- Props: hideOn, translateRange, animationDuration, supportIdle, exclude?, currentId?
<MotionifyBottomTabWithInterpolation>
- Smooth, range-based translation
- Props: inputRange, outputRange, extrapolate, scrollValue?

Presets & Utils

DEFAULTS: threshold, durations, idle timeout, throttle
TRANSLATION_PRESETS: common ranges (e.g., BOTTOM_TAB, FAB_*, HEADER)
INTERPOLATION_PRESETS: fade/scale/parallax/rotate/sticky presets
Helpers: createInterpolation, createFadeInterpolation, createScaleInterpolation, createParallaxInterpolation, createRotationInterpolation, clamp, lerp, mapRange

Examples

Hide Bottom Tab on Scroll

<MotionifyProvider>
  <Screen />
  <MotionifyBottomTab hideOn="down" translateRange={{ from: 0, to: 80 }}>
    <TabBar />
  </MotionifyBottomTab>
</MotionifyProvider>

Programmatically Show/Hide Tab Bar

When user scrolls down, the tab bar hides. If you navigate to another tab programmatically (e.g., via CTA button), the tab bar may remain hidden. Use tabBar.show() to fix this:

import { useNavigation } from '@react-navigation/native';
import { useMotionify } from 'react-native-motionify';

function HomeScreen() {
  const { onScroll, tabBar } = useMotionify();
  const navigation = useNavigation();

  const goToRewards = () => {
    // Ensure tab bar is visible before navigating
    tabBar.show();
    navigation.navigate('Rewards');
  };

  return (
    <ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      <Text>Home Content</Text>
      
      {/* CTA Button that navigates to another tab */}
      <Button title="View Rewards" onPress={goToRewards} />
    </ScrollView>
  );
}

// In your tab navigator, the tab bar stays hidden until show() is called
function AppShell() {
  return (
    <MotionifyProvider>
      <Tab.Navigator tabBar={(props) => (
        <MotionifyBottomTab 
          hideOn="down" 
          translateRange={{ from: 0, to: 80 }}
        >
          <TabBar {...props} />
        </MotionifyBottomTab>
      )}>
        <Tab.Screen name="Home" component={HomeScreen} />
        <Tab.Screen name="Rewards" component={RewardsScreen} />
      </Tab.Navigator>
    </MotionifyProvider>
  );
}

Parallax Header

<MotionifyViewWithInterpolation
  interpolations={{
    translateY: {
      inputRange: [0, 200],
      outputRange: [0, -100],
      extrapolate: "extend",
    },
    opacity: { inputRange: [0, 150, 200], outputRange: [1, 0.5, 0] },
  }}
>
  <Image source={headerImage} />
</MotionifyViewWithInterpolation>

Fade on Scroll

const { onScroll } = useMotionify({ threshold: 20 });

<MotionifyView fadeScale hideOn="down" animationDuration={400}>
  <FAB />
</MotionifyView>;

Custom: build your own animations (no Motionify components)

You can skip MotionifyView/MotionifyBottomTab and drive your own Animated.* components using values from the hook.

import Animated, {
  useAnimatedStyle,
  interpolate,
  Extrapolation,
} from "react-native-reanimated";
import { useMotionify } from "react-native-motionify";

function CustomScreen() {
  const { onScroll, scrollY, directionShared } = useMotionify();

  const animatedHeaderStyle = useAnimatedStyle(() => {
    const translateY = interpolate(
      scrollY.value,
      [0, 200],
      [0, -100],
      Extrapolation.CLAMP
    );
    const opacity = directionShared.value === "down" ? 0.7 : 1;
    return { transform: [{ translateY }], opacity };
  });

  return (
    <Animated.ScrollView onScroll={onScroll} scrollEventThrottle={16}>
      <Animated.View style={animatedHeaderStyle}>
        <Header />
      </Animated.View>
      <Content />
    </Animated.ScrollView>
  );
}

Notes:

Use scrollY and/or directionShared to derive your own animations.
Works with Animated.ScrollView, Animated.FlatList, or any Animated.View.
Keep worklets light; precompute heavy values outside.

Usage recap

Wrap your app with MotionifyProvider once.
In each scrollable screen, call useMotionify() and wire onScroll + scrollEventThrottle={16}.
Choose either:
- Normal screens: use MotionifyView for direction-based effects.
- Bottom tabs: use MotionifyBottomTab (optionally with exclude/currentId).
- Fully custom: use scrollY/directionShared with Reanimated styles.

Performance

Use scrollEventThrottle={16}
Keep worklets light; precompute heavy values
Prefer interpolation for smoother motion
Use LegendList, FlashList or FlatList for long content
