is this the right method instead using bottom bar navigation - flutter

I am new to Flutter. As I understand Bottom Bar Navigation is used for quick navigation between the top-level views of an app. but in my situation, I want to use like this which only button PAY can be clicked.
so is it okay if Im not using BottomBar instead i use as container and place it at bottom?

ya ,The best way is that you can create a container and the button and place it child of bottomNavigationBar so the flutter is automaticaly align it in bottom side
bottomNavigationBar: Container(child: yourcodeHere),

How to achieve this kind of navigation in flutter?

I want you guys' insight on how this kind of navigation can be achieved in Flutter. How can we put navigation bar on the left side of the screen? How this can be done in a cleanest way?

I tried using out of box widgets in flutter. But, nothing seems to match the above navigation logic.
Edit: The navigation bar should stay constant.
So if you want your right-side content to change, based on what you click in the left pane. Check out this video https://youtu.be/eikOZzfc0l4 by the official Flutter channel. I don't remember the details for myself. 😅
Edited:
I would use a stack. At the top of the stack, you can have the navigation bar. At the bottom of the stack is the actual app UI. Upon clicking one of the nav items, the UI at the bottom of the stack changes.

BottomNavigatorBar vs Tabbar on Flutter

I know how can I use tabbar or bottomNavigatorBar. I can create bottom bar with both of them but my question is which one is the best usage to create bottom bar? I mean, which one should I use to create bottom bar?
It will be design based, how you prefer. I prefer using BottomNavigatorBar for <=5 destination. Else, use with Tabbar sometimes.
Let's check the Google material about bottom-navigation
Bottom navigation bars display three to five destinations at the bottom of a screen. Each destination is represented by an icon and an optional text label. When a bottom navigation icon is tapped, the user is taken to the top-level navigation destination associated with that icon.

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.

How to make an expanding navigation bar

I am trying to create an expanding navigation bar. You can see the sketch I've made below.
I just can't find any way to build a custom navigation bar like that.
Does anyone know how to build it + animate a transition? I want it to slide up and down after the arrow in the middle got pressed.
I think what your looking for is a DraggableScrollableSheet. Here is the documentation to it: https://api.flutter.dev/flutter/widgets/DraggableScrollableSheet-class.html

Make multiple scaffold with single Tabs bar

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.
