flutter clear textfield

Comment

//Initialize a controller inside your State class
TextEditingController _controller = TextEditingController();

//Set the _controller on you TextField
TextField(
  controller: _controller,
  //Rest of your code
)

//Clear the controller after pushing the new page
onPressed: () {
   Navigator.push(context, new MaterialPageRoute(
     builder: (context) => SearchPage(searchText: this.search.text)
   )).then((value) {
      //This makes sure the textfield is cleared after page is pushed.
      _controller.clear();
   });
}

error textfield getting clear flutter

Comment

The issue is that you are persisting objects inside a StatelessWidget.

Opening the keyboard tends to rebuild the whole screen (which is fine). But in
my case rebuilding cause your TextEditingController to be GCed because i 
stored them inside a StatelessWidget
