When you want to use the comparison slider with local images, simply add these lines:
import ComparisonSlider from "react-native-comparison-slider";
<ComparisonSlider
imageWidth={667}
imageHeight={400}
initialPosition={50}
leftImage={require("./img/left.jpeg")}
rightImage={require("./img/right.jpeg")}
/>
These code will use the left.jpeg image as the left image and the right.jpeg as the right image. The slider will be half between the image (50). The imageWidth and imageHeight are the size you want your comparison slider to be.
When you want to use the comparison slider with remote images, simply add these lines:
import ComparisonSlider from "react-native-comparison-slider";
<ComparisonSlider
initialPosition={50}
leftImageURI="https://..."
rightImageURI="https://..."
/>
These code will use the leftImageURI as the left image and the rightImageURI as the right image.
The slider will be half between the image (50).
