I have a tab bar in my flutter app. Tab bar view has two screens with two different forms. How ever Im editing a form on 1st tab screen and when I change to the 2nd tabscreen , text field on previous screen is selected. how can i disable keyboard on swipe for tabscreen.
tabController = TabController(length: 2, vsync: this);
tabController?.addListener(() {
if(tabController!.indexIsChanging){
FocusScope.of(Get.context!).unfocus();
}
});
I have tried the above code. But i cant dispose the keyboard on swipe
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());

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 ]);
I have a TabController in flutter which has 4 TabItems. How to push screens inside on any particular tab item with back navigation? instead of opening a new screen which covers the full screen and hides the Tab bar.
Finally after some research, i have achieved this with Cupertino Widgets. Using CupertinoTabScaffold and CupertinoTabBar this can be done.
I implemented tab bar in my application
and then I want tabbar screens to be change when the specific moments occur
but buttons should not be used (for instance, bottom navigation bar buttons)
if you have three tab buttons and assume current screen is first(index 0),
how to accomplish to go to page third?(index 2)
thanks
If you have a TabController even if you don't have a TabBar(but you have a TabBarView with that controller attached) then just use the method animateTo() with the index you want to move and a duration for the animation (if you want a different duration). tabController.animateTo(2)
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

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