Description
When downloading a file from firebase storage, if the file does not exist then when writeToFile() is called then the catch in the below example is not invoked.
However, the catch is correctly invoked when calling other functions, like getMetadata().
Code for writeToFile():
final directory = await getApplicationDocumentsDirectory();
final File file = File(directory.path);
final StorageReference ref = _firebaseStorage.ref().child("Does_not_exist");
try {
final StorageFileDownloadTask downloadTask = ref.writeToFile(file);
await downloadTask.future;
} catch (error) {
print("Error! - " + error.toString());
}Exception that is apparently 'Unhandled':
