I wonder how react native works if component is hidden. For example in this code
{visible && <RkModalImg rkCardImg renderFooter={this._renderHeader} source={{ uri: PhotoURL }} />}
If visible variable is equal to false
does it send request to server ?
In general in javascript, if you do this:
const x = b && b.name // this means if b has value execute b.names otherwaise x will be null
in your case, the component will not get rendered which means it will not execute anything(component doesn't exist).
