Bottom sheet recipe

Depending on bottom sheet implementation in your project, you should use either AvoidSoftInput module or AvoidSoftInputView component.

If your bottom sheet implementation uses React Native Modal component, you should use AvoidSoftInputView component (check Modal recipe). Otherwise use AvoidSoftInput module like in the example below.

This example assumes the bottom sheet is implemented with React Native Bottom Sheet

packages/app/src/screens/BottomSheetExample.tsx

import { BottomSheetModal, BottomSheetView } from '@gorhom/bottom-sheet';
import { useFocusEffect } from '@react-navigation/native';
import * as React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { AvoidSoftInput } from 'react-native-avoid-softinput';
import { SafeAreaView } from 'react-native-safe-area-context';

import Button from '../components/Button';
import SingleInput from '../components/SingleInput';
import { styles as commonStyles } from '../consts/styles';

const Backdrop: React.FC = () => <View style={styles.backdrop} />;

export const BottomSheetExample: React.FC = () => {
  const bottomSheetModalRef = React.useRef<BottomSheetModal>(null);

  function dismissBottomSheet() {
    bottomSheetModalRef.current?.dismiss();
  }

  function presentBottomSheet() {
    bottomSheetModalRef.current?.present();
  }

  const onFocusEffect = React.useCallback(() => {
    AvoidSoftInput.setShouldMimicIOSBehavior(true);
    AvoidSoftInput.setEnabled(true);
    AvoidSoftInput.setAvoidOffset(70);

    return () => {
      AvoidSoftInput.setAvoidOffset(0);
      AvoidSoftInput.setEnabled(false);
      AvoidSoftInput.setShouldMimicIOSBehavior(false);
    };
  }, []);

  useFocusEffect(onFocusEffect);

  return <SafeAreaView edges={[ 'left', 'right' ]} style={commonStyles.screenContainer}>
    <Button
      onPress={presentBottomSheet}
      title="Open bottom sheet"
    />
    <BottomSheetModal
      ref={bottomSheetModalRef}
      backdropComponent={Backdrop}
      enableDismissOnClose
      enableDynamicSizing
      enablePanDownToClose
      index={0}
    >
      <BottomSheetView style={styles.bottomSheet}>
        <SafeAreaView edges={[ 'bottom', 'left', 'right' ]} style={styles.bottomSheet}>
          <Text style={styles.header}>Header</Text>
          <SingleInput style={styles.input} />
          <View style={styles.submitButtonContainer}>
            <Button
              onPress={dismissBottomSheet}
              title="Submit"
            />
          </View>
        </SafeAreaView>
      </BottomSheetView>
    </BottomSheetModal>
  </SafeAreaView>;
};

const styles = StyleSheet.create({
  backdrop: {
    ...StyleSheet.absoluteFillObject,
    backgroundColor: 'rgba(0,0,0,0.5)',
  },
  bottomSheet: {
    alignItems: 'center',
    alignSelf: 'stretch',
    backgroundColor: 'white',
  },
  header: {
    color: 'black',
    fontSize: 28,
    fontWeight: 'bold',
    paddingBottom: 40,
    paddingTop: 30,
  },
  input: {
    marginHorizontal: 50,

  submitButtonContainer: {
