I am trying to develop an app with both a bottom navigation bar and a side navigation bar. The page with the bottom navigation bar works fine when used as a main page. However, when I try to link it with my side navigation bar, I get the following error:
Undefined name 'navigationShell'
How can I resolve this? This is the only error that I am facing.
I tried to create a getter to navigationShell and equate it to null. Also tried creating a local variable, mixing and field in the similar manner but experienced errors in all of them as well when I compiled and ran my app.
