Need help for unfocus keyboard with BackButtonListener()

[md-rifatkhan]

I'm using BackButtonListener for removing focus of the keyboard, but the problem is on first backbutton press hide the keyboard and doesn't trigger onBackButtonPressed(), on second backbutton press trigger it and then unfocus,

My target is to directly unfocus keyboard on single back button press, how to do it?

  Widget _buildTitleField(BuildContext context) {
    return BackButtonListener(
      onBackButtonPressed: () async {
        print("Back button pressed");
        FocusScope.of(context).unfocus();
        return true;
      },
      child: TextField(
        controller: controller.titleController,
 
        cursorColor: Colors.blue,
        style: const TextStyle(fontSize: 20),
        onTapOutside: (pointer) {
          FocusScope.of(context).unfocus();
        },
        onChanged: (text) {
         
        },
      ),
    );
  }
