Usage

1-1. Default Header

import {
  createCollapsibleStack,
  // disableExpoTranslucentStatusBar,
} from 'react-navigation-collapsible';

/* Expo only: If you disabled Expo's default translucent statusBar, please call this function as well.
disableExpoTranslucentStatusBar();
*/

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        /* Wrap your Stack.Screen */
        {createCollapsibleStack(
          <Stack.Screen
            name="HomeScreen"
            component={MyScreen}
            options={{
              headerStyle: { backgroundColor: 'green' },
              title: 'Home',
            }}
          />,
          {
            collapsedColor: 'red' /* Optional */,
            useNativeDriver: true /* Optional, default: true */,
            key:
              'HomeScreen' /* Optional, a key for your Stack.Screen element */,
            elevation: 4 /* Optional */,
          }
        )}
      </Stack.Navigator>
    </NavigationContainer>
  );
}

import { Animated } from 'react-native';
import { useCollapsibleStack } from 'react-navigation-collapsible';

const MyScreen = ({ navigation, route }) => {
  const {
    onScroll /* Event handler */,
    onScrollWithListener /* Event handler creator */,
    containerPaddingTop /* number */,
    scrollIndicatorInsetTop /* number */,
    /* Animated.AnimatedInterpolation by scrolling */
    translateY /* 0.0 ~ -headerHeight */,
    progress /* 0.0 ~ 1.0 */,
    opacity /* 1.0 ~ 0.0 */,
  } = useCollapsibleStack();

  /* in case you want to use your listener
  const listener = ({nativeEvent}) => {
    console.log(nativeEvent);
  };
  const onScroll = onScrollWithListener(listener);
  */

  return (
    <Animated.FlatList
      onScroll={onScroll}
      contentContainerStyle={{ paddingTop: containerPaddingTop }}
      scrollIndicatorInsets={{ top: scrollIndicatorInsetTop }}
      /* rest of your stuff */
    />
  );
};

See /example/App.tsx and /example/src/DefaultHeaderScreen.tsx

1-2. Sticky Header

See /example/src/StickyHeaderScreen.tsx

---

2. Sub Header (e.g Search Bar)

import { createCollapsibleStackSub } from 'react-navigation-collapsible';
/* use 'createCollapsibleStackSub' instead of 'createCollapsibleStack' */

/* The rest are the same with the default header. */

import { Animated } from 'react-native';
import {
  useCollapsibleStack,
  CollapsibleStackSub,
} from 'react-navigation-collapsible';

const MySearchBar = () => (
  <View style={{ padding: 15, width: '100%', height: 60 }}>
    <TextInput placeholder="search here" />
  </View>
);

const MyScreen = ({ navigation, route }) => {
  const {
    onScroll /* Event handler */,
    containerPaddingTop /* number */,
    scrollIndicatorInsetTop /* number */,
  } = useCollapsibleStack();

  return (
    <>
      <Animated.FlatList
        onScroll={onScroll}
        contentContainerStyle={{ paddingTop: containerPaddingTop }}
        scrollIndicatorInsets={{ top: scrollIndicatorInsetTop }}
        /* rest of your stuff */
      />
      /* Wrap your component with `CollapsibleStackSub` */
      <CollapsibleStackSub>
        <MySearchBar />
      </CollapsibleStackSub>
    </>
  );
};

See /example/App.tsx and /example/src/SubHeaderScreen.tsx

3. Custom Header

function App() {
  return (
    <NavigationContainer
      /* Add headerMode="screen" to prevent the custom header from clashing with subsequent headers.
         If you don't do this, you will have to make sure the header is applied consistently.
         You can check the Custom Header implementation example to see a possible configuration for this */
      headerMode="screen"
    >
      <Stack.Navigator>
        /* Wrap your Stack.Screen */
        {createCollapsibleStack(
          <Stack.Screen
            name="HomeScreen"
            component={MyScreen}
            options={{
              title: 'Home',
            }}
          />,
          {
            /* Add a custom header to the createCollapsibleStack options the same way
               you would add it to the Stack.Screen options */
            header: ({ scene, previous, navigation }) => {
              const { options } = scene.descriptor;
              const title =
                options.headerTitle !== undefined
                  ? options.headerTitle
                  : options.title !== undefined
                  ? options.title
                  : scene.route.name;

              return (
                <MyHeader
                  title={title}
                  leftButton={
                    previous ? <MyBackButton onPress={navigation.goBack} /> : undefined
                  }
                  style={options.headerStyle}
                />
              );
            };
          }
        )}
      </Stack.Navigator>
    </NavigationContainer>
  );
}
