A simple code snippet to upload any file type to firebase storage

firebase_file_uploader.dart

```dart
import 'package:mime/mime.dart'; //add mime to pubspec.yaml
import 'package:uuid/uuid.dart'; //add uuid to pubspec.yaml
import 'package:firebase_storage/firebase_storage.dart'; //add firebase storage to pubspec.yaml
import 'package:path/path.dart'; //add path to pubspec.yaml

final firebaseStorage = FirebaseStorage.instance;

Future uploadFile({required File file}) async {
  const uuid = Uuid();

  final String fileName = basename(file.path);
  
  final List<String> mimes = lookupMimeType(fileName)!.split('/');

  final String newFileName = '${uuid.v4()}.${mimes.last}'; //filename with extension
  
  final UploadTask uploadTask = firebaseStorage.ref().child('reports').child(newFileName).putFile(file);
  
  final TaskSnapshot downloadUri = await Future.value(uploadTask);
  
  final String downloadUrl = (await downloadUri.ref.getDownloadURL());
  return downloadUrl;
}
