I am trying to read the device filesystem using react-native-fs. The code works when i console.log the contents directly but result array is always empty. what am I doing wrong?

here is my function :

getFiles = async (dir, result) => {

let contents = await RNFS.readDir(dir);
if(contents.length > 0 ){
    for (let i = 0; i < contents.length; i++) {
        if ( contents[i].isFile() ) {
            result.push(contents[i])
        }
     else if (contents[i].isDirectory()) {
         const newPath = dir + '/' + content[i].name;
         await getFiles(newPath,result)
      }
     }
 }
}
