How to get file size after click image.

[NaitikDartexon]

async function takePicture(){
let mime = require('mime-types')
if( camera ) {
const options = {quality: 0.5,width:1000,height:1000};
const data = await camera.takePictureAsync(options);
let filename = data.uri.substring(data.uri.lastIndexOf('/') + 1, data.uri.length)
console.log("data ====>",filename)
}
}
}

I got the Filename now but what is the option for fileSize, how can i get the filesize any idea?
