React Native save base64 image to Album

Question

Third Party API return a \"QR code image\" in base64 encode,
I need save that image to User\'s Album.

• CamerRoll - not support saving base64 image to album <

Answer 1

Remove data:image/png;base64, in your base64 string

var Base64Code = base64Image.split("data:image/png;base64,"); //base64Image is my image base64 string

const dirs = RNFetchBlob.fs.dirs;

var path = dirs.DCIMDir + "/image.png";

RNFetchBlob.fs.writeFile(path, Base64Code[1], 'base64')
.then((res) => {console.log("File : ", res)});

And then I solved my problem.
