Is there any update on this?

[coffenbacher]

Did anyone figure out a workaround on this?

Edit, here's what I ended up doing, maybe not the slickest thing ever but it works for me:

const example = () => {
  const [wrapperWidth, setWrapperWidth] = useState(0)
  return (
    <View
      style={{ display: 'flex', flexDirection: 'row' }}
      onLayout={event => setWrapperWidth(event.nativeEvent.layout.width)}
    >
      <AutoHeightImage
        width={wrapperWidth}
        source={{ uri: 'https://i.imgur.com/example.png' }}
      />
    </View>
  )
}

@coffenbacher good workaround man... it's still a little strange that react-native don't do it for free... I know they say that they don't add this functionality by default when talking of images taken from the web ({{uri:...}} but this decision should be left to the programmer...
Sorry for the outburst :)

I enhanced @coffenbacher 's solution a little, so you can also use it also as a ImageBackground.

import React, { useState, ReactNode } from "react";
import { ViewProps, View, LayoutChangeEvent, StyleSheet } from "react-native";
import AutoHeightImage, {
    AutoHeightImageProps,
} from "react-native-auto-height-image";

interface WrappedAutoHeightImageProps
    extends Omit<AutoHeightImageProps, "width"> {
    children?: ReactNode;
    containerProps?: ViewProps;
}

/**
 * Uses wrapper to set dynamic width of a AutoHeightImage
 * @see https://github.com/vivaxy/react-native-auto-height-image/issues/9
 */
export const WrappedAutoHeightImage = ({
    children,
    containerProps,
    ...rest
}: WrappedAutoHeightImageProps) => {
    const [wrapperWidth, setWrapperWidth] = useState(0);
    const [imageHeight, setImageHeight] = useState(0);

    const onWrapperLayout = (event: LayoutChangeEvent) =>
        setWrapperWidth(event.nativeEvent.layout.width);

    const onImageLayout = (event: LayoutChangeEvent) =>
        setImageHeight(event.nativeEvent.layout.height);

    return (
        <View
            onLayout={onWrapperLayout}
            {...containerProps}
            style={[
                {
                    alignItems: "center",
                    display: "flex",
                    flexDirection: "row",
                    height: imageHeight,
                    justifyContent: "center",
                    width: "100%",
                },
                containerProps?.style,
            ]}

        >
            <AutoHeightImage
                onLayout={onImageLayout}
                onError={(error) => console.log("error", error)}
                width={wrapperWidth}
                style={[StyleSheet.absoluteFill]}
                {...rest}
            />

            {imageHeight ? children : undefined}
        </View>
    );
};

Usage:

  <WrappedAutoHeightImage
                        source={{
                            uri:
                                "https://cdn.pixabay.com/photo/2018/09/24/03/05/cat-3699032_960_720.jpg",
                        }}
                    >
                        <Text>Cats are small lions, prove me wrong</Text>
   </WrappedAutoHeightImage>

You can still use this component just as an image, if you don't provide children.
