Keyboard overrides the button at bottom of screen in iOS simulator only

Question

I have been trying to scroll my button above the keyboard when keyboard opens, I am using "react-native-keyboard-aware-scroll-view", it becomes handy when I align my button at top just below my text field, but I want my button to be aligned at bottom of screen (flex-end), in this case keyboard covers my button and button doesn't slide up. In Android simulator it is working fine but in iOS it is not. I have tried different things, giving extraScrollHeight also doest work one having one or two text fields and larger screen size. Please suggest something.

Here is my code.

<SafeAreaContainer>
            <KeyboardAwareScrollContainer
                showsVerticalScrollIndicator={false}
                contentContainerStyle={{ flex: 1 }}>
                <FormikContainer>
                    <Formik
                        initialValues={{ email: '' }}
                        onSubmit={values => onSubmitEmail(values)}>
                        {({ values, errors }) => (
                            <FormikInternal>

                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                  
                                />
                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                />
                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                />
                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                />
                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                />
                      
                                <Button bgColor="red">
                                    <Text fontSize={16} color={theme.color.white}>
                                        {LABELS.Continue}
                                    </Text>
                                </Button>
                              
                            </FormikInternal>
                        )
                        }
                    </Formik>
                </FormikContainer>
            </KeyboardAwareScrollContainer>
        </SafeAreaContainer>

Styled Components used

import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view';
import styled from 'styled-components/native';

export const SafeAreaStyled = styled(SafeAreaView)`
    flex: 1;
    background-color: ${({ backgroundColor, theme }) => backgroundColor || theme.color.white};
    padding-horizontal: ${({ paddingHorizontal }) => `${scale(paddingHorizontal)}px`};
    padding-vertical: ${({ paddingVertical }) => `${scale(paddingVertical)}px`};
`;

export const KeyboardAwareScrollContainer = styled(KeyboardAwareScrollView)`
    background-color: ${({ backgroundColor, theme }) => backgroundColor || theme.color.white};
`;
export const FormikContainer = styled.View`
    flex: 1;
    margin-top: ${scale(32)}px;
    background-color: ${({ theme }) => theme.color.white};
`;
export const FormikContainer = styled.View`
    flex: 1;
    margin-top: ${scale(32)}px;
    background-color: ${({ theme }) => theme.color.white};
`;

I am thinking of making keyboard opening listeners and giving button margin of keyboard height when keyboard is open but that's last solution, if any thing else, please suggest.

Answer 1

One can made it working on iOS using keyboard height. You can make a custom hook for getting keyboard height and give button margin from bottom according to keyboard height. It will work for iOS and for android above code works fine.

UseKeyboardHook

import { useEffect, useState } from 'react';
import { Keyboard } from 'react-native';

export const useKeyboard = () => {
    const [keyboardHeight, setKeyboardHeight] = useState(0);
useEffect(() => {
        const keyboardDidShowListener = Keyboard.addListener('keyboardDidShow', e => {
            setKeyboardHeight(e.endCoordinates.height);
        });
        const keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', () => {
            setKeyboardHeight(0);
        });
        return () => {
            keyboardDidHideListener.remove();
            keyboardDidShowListener.remove();
        };
    }, []);
    return keyboardHeight;
};

Component having keyboard aware scroll view

export const YourComponent = () => {
    
    const keyboardHeight = useKeyboard();
    return(
           <SafeAreaContainer>
            <KeyboardAwareScrollContainer
                showsVerticalScrollIndicator={false}
                contentContainerStyle={{ flex: 1 }}>
                <FormikContainer>
                    <Formik
                        initialValues={{ email: '' }}
                        onSubmit={values => onSubmitEmail(values)}>
                        {({ values, errors }) => (
                            <FormikInternal>

                                <TextInput
                                    style={styles.input}
                                    onChangeText={ (val) => {console.log(val);}}
                                    value={values.email}
                                  
                                />
                                <Button bgColor="red" marginBottom={Platform.OS === 'ios' ? keyboardHeight: 0}>
                                    <Text fontSize={16} color={theme.color.white}>
                                        {LABELS.Continue}
                                    </Text>
                                </Button>
                              
                            </FormikInternal>
                        )
                        }
                    </Formik>
                </FormikContainer>
            </KeyboardAwareScrollContainer>
        </SafeAreaContainer>)
    }
