Is it possible to get the final width and height of the image after resize?

You can write your own function to do that

import {Image} from "react-native";

export async function getImageDimensions(imageUri) {
    return new Promise((resolve, reject) => {
            Image.getSize(imageUri, (width, height) => {
                resolve({width, height});
            }, error => reject(error));
        }
    );
}

Usage:

const imageDimensions = await getImageDimensions(pathToImage);

You can use this in combination of the image resize function to return both the path to the new image and its dimensions
