I'm trying to make a page design like this:

But I'm having difficulties on implementing the tab bar. When the user click on 'Detail', then the detail view is showed under the tab bar and so on. Is there any widget to use?

try CupertinoSlidingSegmentedControl:

child: CupertinoSlidingSegmentedControl(
                    children: {
                      0: Text("FLIGHTS"),
                      1: Text("TRAINS"),
                      2: Text("HOTELS")
                    },
                  onValueChanged: (value)
                  {
                    selectedValue = value;
                    setState(() {

                    });
                  },
                  groupValue: selectedValue,
                ),
