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 have an appbar which is used in more than one screen. I have a navigation drawer in the home screen. As the appbar is used in multiple places, i created as a separate widget. But I am not able to access navigation drawer. So I included appbar code in all the screens I needed. Then it works fine. But it will be code duplicate. Is there any fix for this in Flutter?
Thanks.
If you have not done so yet , you can make a separate class for drawer
getAppDrawer(){
return Drawer(
//your code
);
}
and then you can call this in your others screen
drawer : getAppDrawer(),
you can also do this for the appbar
Take a look at the examples here
and here
I'm using Custom Tab navigator to manage persistent bottom navigation bar across all the screens.
Due this Tab navigator sits in one StatefulWidget to host the tabs in the app, So unable to pop to the other widget out of these tabs and hosted widget.
Ex : After successful login, There is one widget Dashboard and it hosts the bottom navigation and tabs using Navigator. Now i want to logout from one of the tab and should navigate to the login screen, which is not part of any tabs or hosted widget.
While trying to push to Login widget, Showing only the blank screen. Because no route within the Custom navigator.
Any solution for this without using any package for persistent bottom navigation.
I am trying to create a android tab bar like this image custom tab bar in flutter.
How can I make a tab bar like this?
There are so many examples for your questions you can check the links. Also appbar is a widget on the top of the screen and has buttons. You can create a buttons in the scaffold widget and put them top of the screen still same but easy to decorate and use.

Custom AppBar
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 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.
