I want to randomise the return of an image in a folder but I have the error 'Invalid call'
my function:
returnGif = () => {
min = Math.ceil(1);
max = Math.floor(53);
const gifNumber = Math.floor(Math.random() * (max - min +1)) + min;
var gifFont = require('../config/Images/Gifs/' + gifNumber + '_2.png');
if (gifFont) {
if (Math.random()>0.5) gifFont = require('../config/Images/Gifs/' + gifNumber + '_2.png');
else gifFont = require('../config/Images/Gifs/' + gifNumber + '.png');
}
else gifFont = require('../config/Images/Gifs/' + gifNumber + '.png');
return gifFont;
}
In react native ,Dynamic paths in require are not currently supported.
you need to import all images and then use case for randomization
for example
function getavatarImage(avatar) {
switch (avatar) {
case "spiderman":
return require('./spiderman.png');
case "batman":
return require('./batman.png');
case "hulk":
return require('./hulk.png');
default:
return require('./no-image.png');
}
}
