Thanks again, I want to use the WillPopScope as follows, I have a Textfield if the user press the back button at the bottom of an Android phone I want the keyboard to disappear and set the unfocus on the textfield, how would you say to do this, Pierre

In my case, onWillPop: is expected boolean, which is ok as per the video. But showDialog is returning Future<dynamic>, any suggestions
