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.

In Flutter, I need to pop the route stack until I get to a modal bottom sheet, but I can't figure out how to do that using Navigator.popUntil .
The scenario is this: I have a settings screen (lets call it SettingsScreen) which you can reach in a number of different ways from the main HomeScreen, resulting in a different stack of routes in the navigator. So for example the stack could be:
HomeScreen -> ScreenA -> SettingsScreen
or
HomeScreen -> ScreenA -> ScreenB -> SettingsScreen
Now I need a way to pop until I get to the HomeScreen. Normally I would achieve this using:
Navigator.popUntil(
context,
(Route<dynamic> route) => route.settings.name == "HomeScreen"
);
But here's the catch: sometimes there will be a modal bottom sheet open in the HomeScreen, and I need that to remain open. Since a modal bottom sheet is a route on the stack, if the sheet is open, the stack might be for example:
HomeScreen -> _ModalBottomSheetRoute<dynamic> -> ScreenA -> ScreenB -> SettingsScreen
So popping until I hit the HomeScreen causes the modal bottom sheet to pop, which closes it. So, I need to pop until I get to the HomeScreen OR until I get to _ModalBottomSheetRoute<dynamic>.
Unfortunately the bottom sheet route has no name or arguments in it's settings, and the runtime type of _ModalBottomSheetRoute<dynamic> is private so I can't even use that as a test. So how do I change the logic in Navigator.popUntil to stop when it gets to the modal bottom sheet? Or is there another way of doing this?
how about passing route settings to showModalBottomSheet(... routeSettings: RouteSettings(name: 'MyModalBottomSheet'))? You could then test for the name given in popupUntil....
I use the bottom navigation bar. Various pages remain stacks through push on A_Page, one of the bottom navigation items.
If you press the button on the top page, I want to clear all stacked pages, leaving only A_Page, the first page of the bottom navigation item. I think using Navigator.pop several times is a bad code.
How do I clear a pushed page except the first bottom navigation item page?
Navigator.popUntil(context, (route) => route.isFirst);
You can use named routes
Navigator.of(context).pushNamedAndRemoveUntil(
'/first_screen',
(Route<dynamic> route) => false,
);
I have an app with bottom navbar. I can navigate between pages through the navbar. My problem is when i go to another page (not a button for this page on navbar) navbar disappears. I used that code below when click button and go to another page. But as i said navbar dissappears. I want navbar always stay.
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => ProgrammingScreen()));
I tried PageView widget but i could'nt navigate pages from buttons. How can i solve this problem?
One option is to all those screens be in the page view widget.
But another thing you can do is put the exact same bottom nav bar in the new pushed screen and if the user selects an option. You can use Navigator.pop() and then navigate to the pageView with the selected option
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 am building a flutter app where the user requirement is to build 3 tabs with each tab having custom AppBar which implies to have multiple Scaffolds in each view.
So I have main.dart, screen.dart, account.dart and post.dart
3 tabs => Screen, Account and Post
Screen View => Appbar with just name
Account View => Appbar with Hamburger Icon
Post View => Appbar with Plus icon
According to flutter we can have Appbar and Bottom Navigation Bar (Tabs Bar) inside Scaffold Widget. So to have multiple Scaffolds, I would have to make 3 seperate bottom navigation bar or is there any other way to achieve this functionality?
Also, if we need to make 3 different Bottom Navigation Bar per Scaffold, then how to navigate between them since my first view will be called from main.dart
Thanks for helping and taking out your time to answer the question.
