Answer 1

You can try using a local notification with react-native-push-notification
Here's how you can do it:
first of all, import the library
import PushNotification from 'react-native-push-notification'
and then, the function itself:
RNFetchBlob.fs.writeFile(path, Base64Code[1], 'base64')
.then(res => {
console.log(res);
if (res > 0) {
PushNotification.localNotification({
id: '69',
ticker: "Download sucess!",
autoCancel: true,
vibrate: true,
vibration: 300,
ongoing: false,
priority: "high",
visibility: "private",
importance: "high",
title: "My app name",
message: "Your file has now ben saved!"
});
} else {
PushNotification.localNotification({
id: '69',
ticker: "Download error!",
autoCancel: true,
vibrate: true,
vibration: 300,
ongoing: false,
priority: "high",
visibility: "private",
importance: "high",
title: "My app name",
message: "Errors ocurred while saving the file!"
});
}
});

RNFetchBlob.fs
.writeFile(pathToWrite, data, 'utf8')
.then(() => {
RNFetchBlob.android.addCompleteDownload({
title: 'data.pdf',
description: 'Download complete',
mime: 'application/pdf',
path: pathToWrite,
showNotification: true,
});
console.log(`wrote file ${pathToWrite}`);
})
.catch((error) => console.error(error));
