I have a tabview that I want to pass multiple widget to it depending on which screen the user navigated to. The first screen only contains two children while the other one contains four children. I have conditionally passed four Widgets to the other one but it only picked three meaning that my conditions are wrong and it’s also giving me this error. Controller’s length property (4) does not match the number of children (3) present in TabBarView’s children property.
From the attached image, you will see that I tapped on the Archdiocese text and it's returning me the national screen which supposed not to be so.
I really need help on how to navigate them all sequentially
The Paytype there is just an enum
