certain tab bar views reset button with the tabbar maintained - flutter

There are four tabbars, and the ui is created when you attempt to reset the page ui in the tabbarview number 2. I want to create a tabbarview again while maintaining four tabbars.
Navigator.pushReplacement(context,
MaterialPageRoute(builder: (BuildContext context) =>tabbarview() ));
or
Tabview with an index of 2 on a tab bar with 4 pages was reset to its initial state with a button.
If you press the button, all the tab bars disappear...
Navigator. push Replacement (context,
Page RouteBuilder (
pageBuilder: (_, __, ___) => hintPage(),
위 button을 실행하면 TABBAR---> disappear

How to switch the screen smoothly?

I have three screens: 1, 2, and 3.
I want to switch from screen 2 to screen 3, but when I pop screen 2 and push screen 3, then it shows screen 1 for a while, then it shows screen 3, so is there any way to switch screens using pop after push or not?
this code not expectations
Navigator.push(
context,
MaterialPageRoute<Widget>(
builder: (context) => widget,
),
);
Navigator.pop(context);
Using pushReplacement insted of push
Navigator.pushReplacement(
context,
MaterialPageRoute<Widget>(
builder: (context) => widget,
),
);
Using pushReplacement insted of push
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => widget,
),
);
The behavior you're describing is likely because when you call Navigator.pop(context), it removes the current screen (screen 2) from the navigation stack, but the framework hasn't yet had a chance to build and display the new screen (screen 3) that you pushed. So, for a brief moment, the previous screen (screen 1) is visible.
One way to switch screens without that flicker is to use Navigator.pushReplacement instead of Navigator.push followed by Navigator.pop. Navigator.pushReplacement removes the current screen from the navigation stack and replaces it with the new screen, all in one step.
Example:
Navigator.pushReplacement(
context,
MaterialPageRoute<Widget>(
builder: (context) => widget3,
),
);
This will directly switch from screen 2 to screen 3.
It is generally not recommended to use both Navigator.push() and Navigator.pop() together in the same function call, as this can cause unexpected behavior. Instead, you can use Navigator.replace() to replace the current screen with a new one, or use Navigator.pushNamedAndRemoveUntil() to push a new screen and remove all the screens that come before it.

Flutter Drawer Navigation

I have a list of Screens in a custom drawer.
Screen 1,
Screen 2,
Screen 3
What is the proper way of navigating from Screen 1 to Screen 2 on push of a button. Currently, I am losing the hamburger (the drawer button) option when I push or push replace.
The code I have was not written by me and I do not have access to the person who wrote the code.
Any thoughts?
Just use the standard navigation:
TextButton(
onPressed: (){
Navigator.push(context, MaterialPageRoute(builder: (context) => Screen2()));
}
child:
//child goes here
)

Flutter 1.22.2 navigation pop transition duration not matching push

I have just recently upgraded to Flutter 1.22.2 and saw some differences even though Flutter release notes indicated that navigation system remains the same.
I have 2 pages and I use push method to transition from the 1st page to the 2nd page. I have added a Transition Duration from 1st to 2nd page (code below). Prior to this version, when I pop from 2nd page to 1st page, the delay is matching the 1st to 2nd page. After the update, the when I pop from 2nd page to 1st page, the animation is very fast.
Code:
Navigator.push(
context,
PageRouteBuilder(
transitionDuration: Duration(seconds: 1),
pageBuilder: (_, __, ___) => goto2ndPage(),
transitionsBuilder: (_, animation, __, child) => FadeTransition(
opacity: animation,
child: child,
),
),
);
For pop:
onPressed:
() => Navigator.of(context).pop(),
),
Can someone advice how I can delay the pop transition from 2nd page to 1st page?
add reverseTransitionDuration to your navigation push.

Use popUntil Navigator method with custom transition animation

I have 3 screens A -> B -> C. Screen B is pushed from screen A, screen C is pushed from B. My goal now is to call this method of navigator:
Navigator.popUntil(
context,
(route) => route.isFirst,
);
But apply custom animation like I was doing when pushing those screens. Example of animation I was using when pushing screen was this (where screen slides from the top):
Navigator.push(
context,
SlideInRoute(
page: ScreenB(),
direction: SlideInDirection.Top,
),
);
End result now is that I've made FlipRoute class that flips 2 screens, and I want flip to root.
