Resizing the height based on screen size width

[shawnmclean]

Hey there! Great project!

I'm trying to get a sort of image gallery carousel that has a max height and will reduce the height based on the height of the image inside.

Is there a way to accomplish this with stylings or do I need to recompute the height property for the <Carousel>?
Can it do a sort of fit to content?

Hey @shawnmclean! I'm here to help you with any bugs, questions, or contributions you have for the project. Let's tackle this issue together!

To create an image gallery carousel that adjusts its height based on the height of the images inside, you can dynamically recompute the height property for the <Carousel> component. Here is an example of how you can achieve this using React Native and the react-native-reanimated-carousel library:

import React, { useState, useEffect } from 'react';
import { View, Image, Dimensions } from 'react-native';
import Carousel from 'react-native-reanimated-carousel';

const screen = Dimensions.get('window');

const ImageCarousel = ({ images }) => {
    const [carouselHeight, setCarouselHeight] = useState(0);

    useEffect(() => {
        if (images.length > 0) {
            Image.getSize(images[0], (width, height) => {
                setCarouselHeight(height);
            });
        }
    }, [images]);

    return (
        <Carousel
            style={{ width: screen.width, height: carouselHeight }}
            width={screen.width}
            data={images}
            renderItem={({ item }) => (
                <View style={{ flex: 1 }}>
                    <Image
                        source={{ uri: item }}
                        style={{ width: screen.width, height: carouselHeight }}
                        resizeMode="contain"
                    />
                </View>
            )}
        />
    );
};

export default ImageCarousel;

In this example:

1. The useEffect hook is used to get the dimensions of the first image in the images array.
2. The setCarouselHeight function sets the height of the carousel based on the height of the first image.
3. The Carousel component's style and renderItem properties are updated to use the dynamically computed height.

This ensures that the carousel's height adjusts based on the height of the images inside ^[1].
