Implementing custom bottom tab navigator flutter - flutter

I am trying to implement a custom bottom tab navigator by doing step by step from this source: https://medium.com/coding-with-flutter/flutter-bottomappbar-navigation-with-fab-8b962bb55013. It uses the combination of floating action bottom and BottomAppBar. The problem is.. if I click the floating action button to navigate user to a screen the bottom tab navigator will be lost. Is there a way to keep bottom tab navigator is still exist when user click the floating action button (where the button will navigate to a screen) or is there a way to make custom bottom tab navigator like this without floting action button:

you have to use nested navigation. here is a tutorial.

Flutter: Unable to go to login view from a persistent bottom nav bar based view

I have a persistent bottom nav bar based on this plugin.
The plugin allows building a page with few footer buttons and navigation etc. But, Once such a page has a logout button that must send the user back to Login view (outside of navbar) and I am stuck here. I've permuted with all the navigator operations available and am stuck here, unable to show a page without the bottom navbar appearing.
Any help is much appreciated! :)

Swift 4: Click button to next View Controller but the new page's animation is "cover vertically" instead of "shifting" to next page

I am newbie of Swift 4 and I am trying to simply click a button and go to next page.
So I add a button in the first page and another view controller. Then I drag the button to the next page to create the "transaction". However, the animation of the transaction to pop up the next page from bottom, as shown in the image below. What I expect is to shift horizontally from current page to next page. Where did I do wrong? How can I achieve this?
Select the first view controller and choose Editor > Embed In > Navigation Controller. Make sure your segue is Show (Push).

Add custom button in install4j

Is it possible to add a custom button (say, a retry one) on a configurable form, but have it placed on the bottom controls, next to the next and back buttons?
As of 6.x, it is not possible to customize the navigation bar or an arbitrary screen with the buttons at the bottom of the installer window.
If you write your own custom screen with the API, you can override hasDefaultButtons() and provide navigation controls yourself. To move to the next and previous screen, you would call context.getWizardContext().pressNextButton() or context.getWizardContext().pressNextButton(). To cancel, call context.getWizardContext()().pressCancelButton()

Won't add navigation item to navigation bar in xcode

I'm trying to create a back button on my navigation bar in x code. However when I drag it across from the objects library to the navigation bar in the storyboard it doesn't come up.
OK So this is crazy but...
Click on the navigation bar and in the attributes inspector, Just Type something in the field marked Back Button. Then in the scene hierarchy you'll see the button, though it won't yet appear on your navbar. In the hierarchy, drag the button onto the Navigation Item and viola it appears. Now to make second one, hold option and copy the first one. If you try to add one from the object browser, you'll lose the first one.
If done properly, the first will show up on the right and the second on the left.
Good luck.
This happens when the navigation is not set up correctly, as dbajkovic mentioned, if you do not have a navigationcontroller, it will not work. Your scoreboard should look like this:
You can not add the button to the left, only to the right.
#Jonathan Thompson: I came across your post and since I just learnt something new, I am going to add it as a response to your question.
There are two separate buttons - Back button and Bar Button. Back button has a reverse (right to left) pointing arrow and a Bar button is a regular rectangular button. The following describes how your could implement them in your program:
Back button:
On the root view controller, ctrl + click on button and drag it to the view controller you are trying to connect it to. When you are given an option to select from, choose Push, not modal. This will automatically add a back button on the next view controller. (Run the program to confirm it.)
Bar Button: (Credit: dbrajkovic)
For adding the bar button, click on navigation bar of the navigationViewController you are interested in. Under Attributes inspector, type some name in Back Button and hit enter to confirm. Open document outline and locate the viewController you were working on. On the left side of Navigation Item locate the disclosure triangle. Click on the Bar Button Item. Ctrl + click + drag the button to the navigation bar of that viewController. You can choose whether to place it on the left / right side.

NavigationBar Right Button Problem

I have a navigation bar in my app. The below pictures are in the order of navigation.
Problem I have is, on clicking the "Main" button , I am able to perform the action and goto the required screen , but the navigation bar does not look like the first on (with Menu as left button). Instead it look like 4th image. How to make it look like first image so that I can make the user to navigate to "Menu" screen by clicking menu button ?. Thanks for the help …!!!
If I'm understanding this correctly, you may have pushed the first view controller (The one from screenshot 1) when clicking on main which is why you see "lens" in the back button. That back button takes the title of the previous view controller in the stack. What you want to do is pop to the first view controller when they click on Main using either popToRootViewController or popToViewController:animated
