ToastrHelper class

Helper class with convenient methods for showing different types of toastrs.

Zero setup required. Just call static methods from anywhere:

Toastr.success('Operation completed!');
Toastr.error('Something went wrong!');
Toastr.loading('Please wait...');
Toastr.promise(myFuture, loading: 'Loading...', success: 'Done!', error: 'Failed');

All methods return a String toast ID that can be used with dismiss or update.
