This seems to be a great alternative to avoid null checks while retrieving values in mutable live data. But i m getting an issue where this can't be used in two-way data binding. I get the following error

The expression 'viewModelValue.getValue()' cannot be inverted, so it cannot be used in a two-way binding

Details: There is no inverse for method getValue, you must add an @InverseMethod annotation to the method to indicate which method should be used when using it in two-way binding expressions

If possible, could you please have a look on what can be done here.
