How to properly handle any exceptions while uploading in firebase storage in flutter

Question

Here's my function to upload the 2 files into firebase storage I am not sure if i am using proper exception handling and second of all where to put the await statement to give time for uploading itself.

void _uploadtocloud() async {
    //File? filesong,fileimage; initialized outside the function
    String songname = songName.text.toString();
    String thumbnail = '${songName.text}thumbnail';

    final Reference storageRef =
        FirebaseStorage.instance.ref().child('music/$songname');
    final UploadTask uploadTaskSong = storageRef.putFile(filesong!);
    final Reference storageRefimage =
        FirebaseStorage.instance.ref().child('image/$thumbnail');
    final UploadTask uploadTaskimage = storageRefimage.putFile(fileimage!);
    final TaskSnapshot snapshot1 = await uploadTaskSong;
    final TaskSnapshot snapshot2 = await uploadTaskimage;

    if (snapshot1.state == TaskState.success &&
        snapshot2.state == TaskState.success) {
      await Future.delayed(const Duration(seconds: 10));
//is this the right place to put await statement.
      setState(() {
        uploaded = true;
        songName.clear();
      });
    } else {
      setState(() {
        uploadfaliure = true;
      });
    }
  }
