In the documentation, it mentions:
You can include multiple remote URLs in this prop, along with their respective width and height values, and potentially other scale/URI arguments.
Could someone explain how to specify more than one URI for the image component in react-native? The documentation does not provide an example for this scenario. Additionally, how can the height and width arguments be passed along with the URI as described in this documentation.
To locate the answer, examine the react-native source code found within
/node_modules/react-native/Libraries/ImageImageSourcePropType and ImageProps.
As per the specifications outlined in ImageSourcePropType, a URI object should adhere to the following structure (allowing for any defined properties as long as the data type matches the expected format):
const ImageURISourcePropType = PropTypes.shape({
uri: PropTypes.string,
bundle: PropTypes.string,
method: PropTypes.string,
headers: PropTypes.objectOf(PropTypes.string),
body: PropTypes.string,
cache: PropTypes.oneOf([
'default',
'reload',
'force-cache',
'only-if-cached',
]),
width: PropTypes.number,
height: PropTypes.number,
scale: PropTypes.number,
});
According to ImageProps, the source attribute can accept an object conforming to the shape of ImageSourcePropType, an array containing such objects, or a number (pertaining to local assets where require('imgs/image1.png') yields a unique identifier for that asset). Here is the relevant code snippet:
const ImageSourcePropType = PropTypes.oneOfType([
ImageURISourcePropType,
// Opaque type returned by require('./image.jpg')
PropTypes.number,
// Multiple sources
PropTypes.arrayOf(ImageURISourcePropType),
]);
Hence, the source property can accept either a single object conforming to ImageURISourcePropType or an array of such objects.
To effectively pass multiple remote images while specifying their respective widths, the process would resemble the following example:
<Image
source={[
{
uri: 'https://image.location.com',
width: 500,
height: 500
},
{
uri: 'https://image2.location.com',
width: 600,
height: 600
},
{
uri: 'https://image3.location.com',
width: 700,
height: 700
},
]}
