Answer 1

Adding a to the root of my app seemed to interfere with the that was already there (which already uses PortalProvider under the hood). Only every other bottom sheet I opened would become visible.

I got mine working simply by wrapping my react-navigation modal screen's contents in a :

 function AppStack() {
            return (
                <NativeStack.Navigator>
                    {/* ... */}
                    <NativeStack.Group screenOptions={{ presentation: 'modal' }}>
                        <NativeStack.Screen 
                            name="MyScreenThatNeedsToBeAbleToOpenABottomSheetModal" 
                            component={MyScreenThatNeedsToBeAbleToOpenABottomSheetModal} 
                        />
                    </NativeStack.Group>
                </NativeStack.Navigator>
            )
        }
    
function 
import React from 'react';
import { View, Button } from 'react-native';
import { BottomSheetModalProvider, BottomSheetModal } from '@gorhom/bottom-sheet';
import { NativeStackScreenProps } from '@react-navigation/native-stack';

type RootStackParamList = {
  MyScreenThatNeedsToBeAbleToOpenABottomSheetModal: undefined;
};

type Props = NativeStackScreenProps<RootStackParamList, 'MyScreenThatNeedsToBeAbleToOpenABottomSheetModal'>;

const MyScreenThatNeedsToBeAbleToOpenABottomSheetModal: React.FC<Props> = ({ navigation }) => {
  const bottomSheetModalRef = useRef<BottomSheetModal>(null);

  const handleOpenBottomSheetModal = () => {
    bottomSheetModalRef.current?.present();
  };

  return (
    <BottomSheetModalProvider>
      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
        <Button title="Open Bottom Sheet Modal" onPress={handleOpenBottomSheetModal} />
      </View>
      <BottomSheetModal
        ref={bottomSheetModalRef}
        index={0}
        snapPoints={[300, 200, 0]} // Define your desired snap points here
      >
        {/* Content of your bottom sheet modal */}
        <View style={{ backgroundColor: 'white', padding: 16 }}>
          {/* Your bottom sheet modal content here */}
        </View>
      </BottomSheetModal>
    </BottomSheetModalProvider>
  );
};

export default MyScreenThatNeedsToBeAbleToOpenABottomSheetModal;

Answer 2

The modal's height should now match the value you entered in the styles' height attribute.modalCard object.

import { StyleSheet } from 'react-native';

const styles = StyleSheet.create({
  modalCard: {
    height: 400, // Set the desired height here
    borderRadius: 10,
    backgroundColor: 'white',
  },
});

export default function OthersScreen({ navigation }) {
  return (
    <View className={'ml-4 p-3 mr-4 mt-1'}>
      <Text className={'text-3xl font-bold'}>Other Location</Text>
      <Text className={'text-sm mt-4 mb-1'}>Latitude: 19.67</Text>
      <Text className={'text-sm mb-1'}>Longitude: 100.34</Text>
      <Text className={'text-sm mb-1'}>Timestamp: 2022-08-21 12:30 PM</Text>
      <Text className={'text-sm mt-4 font-bold'}>Remarks</Text>
      <TextInput
        className={'mt-1 border rounded-lg p-7'}
        placeholder="Please enter reamarks here"
        placeholderTextColor="#000"
      />
      <View className={'mt-4 items-center flex-row space-x-5 '}>
        <TouchableOpacity
          className={'p-3 w-40 items-center justify-center border rounded-lg'}
          onPress={() => navigation.goBack()}
        >
          <Text className={'text-sm'}>Cancel</Text>
        </TouchableOpacity>
        <TouchableOpacity
          className={
            'bg-gray-400 p-3 w-40 items-center justify-center rounded-lg'
          }
        >
          <Text className={'text-sm text-white'}>Check-In</Text>
        </TouchableOpacity>
      </View>
    </View>
  );
}

<Stack.Screen
  name="Other Location"
  component={Others}
  options={{
    headerShown: false,
    cardStyle: styles.modalCard,
  }}
/>
