Allow changing tabBarLabel or title during runtime

[SumitR9910]

Currently it is not possible to change the tabBarLabel or title during runtime, changing the title on runtime throws this error:

Implementation of this functionality will enable performing tasks like changing the language of the tab bar label based on the set app language.

Thanks, I think this should be considered as a bug. I will create an issue for this.

Hey @SumitR9910, FYI support for this has been added in 0.8.1
