You can try this, it will hide the navigation bar, when your field is submitted.
TextFormField(
onFieldSubmitted: (string){
SystemChrome.setEnabledSystemUIOverlays([]);
},
);

How to hide system navigation bar in flutter? I have tried hiding it with
SystemChrome.setEnabledSystemUIMode(SystemUiMode.manual,
overlays: [SystemUiOverlay.top]);
But when ever a touch happens on the app, the system navigation popups first. I need to only display the statusbar. How can I turnoff the system navigation bar ?
Use setEnabledSystemUIMode and provide SystemUiMode.manual as shown below:
SystemChrome.setEnabledSystemUIMode(SystemUiMode.manual, overlays: [ SystemUiOverlay.top ]);

Please try the below code. I wish it will solve your problem.
SystemChannels.textInput.invokeMethod('TextInput.hide');
You are doing it in the wrong way, try this simple method to hide the soft keyboard.You should wrap your whole screen in the GestureDetector method and onTap method write this code.
FocusScope.of(context).requestFocus(new FocusNode());
I'm trying to make a turn by turn navigation app with flutter but I have a problem. I am using the Mapbox navigation package and I want the navigation screen to remain in the screen where I called it, not to open another screen. How can this be achieved?
if you are trying to navigate based on markers, you can do that using the ontap method inside the marker function.
onTap: (){
Navigator.push(context, MaterialPageRoute(builder: (context)=>Page()),);
}
you can do the navigation replacing the Page to which ever widget you want.
I want to pop my bottom modal sheet when my keyboard is hidden. But currently when I press back button keyboard gets hidden but bottom modal sheet remains opened.
I tried using package flutter_keyboard_visibility to detect if the keyboard is hidden and tried to pop the bottom navigation bar. But now when do that and press outside barrier to dismiss, there are two calls to Navigator.pop(context) method. One after hiding the keyboard and another built-in pop by the bottom modal sheet.
Can anyone help me find out how to achieve this?
Thanks.
I would do it the following way:
a) Return WillPopScope inside the Widget build method
b) As a callback for WillPopScope I will Navigator.pop(context)
You can also try the keyboard_visiblity plugin. This will provide you a callback easily.
Did you try using setState(() {}); ?
it will also helps for updating the state of screen
I have a Screen which contains two tab bars. Out of which one Tab bar view has button inside it. I want to load a new screen in the same tab view on button click.
In the image attached you can see a button.
On clicking Go to Details button I want to load details Page in the the same tab bar view.
Full example on DartPad
TabBarView(children: [
Navigator(
onGenerateRoute: (settings) => MaterialPageRoute(
builder: (context) => YourContent(),
),
)
])
You can use setState((){}) to reveal data on screen but you cannot navigate to other screen only inside one tabbar view.
You can use Navigate.pushNamed() to navigate to other screen.
