No TabController for TabBar. When creating a TabBar, you must either provide an explicit TabController using the "controller" property, or you must ensure that there is a DefaultTabController above the TabBar.
Thanks for the video! Do you know how to create 2 tabbars in Scaffold()? I try to make one in the AppBar and one in the BottomAppBar but fail. I've searched the StackOverflow but it seems no answer 😢
@@FlutterCool your welcome, Do you know the slack app ? It has a custom textfield which is slidable, when we slide up on that textfield it expand till app bar, so we can write multi lines Please make a video on it. Also add text format options like slack app has.
