You can handle the storage exception and display a custom error message when a particular file is absent in the Firebase Storage.
Here's an example of how you can achieve this:
import 'package:firebase_storage/firebase_storage.dart';
import 'package:flutter/services.dart';
try {
// your code to upload/download the file
} on PlatformException catch (e) {
// handle the storage exception
if (e.code == 'storage/object-not-found') {
// show custom error message when file is absent
print('File not found');
} else {
// handle other storage exceptions
print('Error: ${e.message}');
}
} catch (e) {
// handle other exceptions
print('Error: $e');
}
In the above code, we're catching the PlatformException
thrown by Firebase Storage. If the exception code is storage/object-not-found
, we can assume that the file is absent, and we can display a custom error message. For other storage exceptions, we can print the error message.
if (e.code == 'storage/object-not-found') {
// show custom error message when file is absent
Navigator.of(context).push(
MaterialPageRoute(
builder: (context) => FileNotFoundErrorScreen(),
),
);
}
In the above code, we're navigating to a different screen when the file is absent, instead of showing a custom error message. You can customize this logic as per your requirement.
I hope this helps! Let me know if you have any further questions.
