you can achieve that by changing how the page view should respond to user input using the physics property. and we have a NeverScrollableScrollPhysics for that purpose so just change physics to that like this :
TabBarView(
physics: NeverScrollableScrollPhysics(),
controller: tabcontroler,
children: <Widget>[
Container(color: Colors.red),
Container(color: Colors.green),
Container(color: Colors.blue),
],
),
