Navigation in flutter – how to add stack, tab, and drawer navigators to your apps - Flutter Agency
If we design or develop apps, we have to focus on the type of navigation used. Of course, as a developer, it is a must to try Flutter as the best framework. Here, the flutter web app development takes full pledge guidance regarding adding stack, tab and drawer navigation to your apps professionally.
There are 3 types of navigation used in the common for all apps. Flutter is supportive in focusing on these types which is similar to how to do in the other apps. They are rather focused on navigation into the Flutter app. When building a Flutter app, you have to learn about the types of navigation used in design and development.
Types of navigation you must know
When you develop apps, you must notice the basic three types of navigation in detail. However, developers are keen on guiding the use of the navigation types accordingly.
Stack Navigation
Tab Navigation
Drawer Navigation
What is stack navigation?
Stack navigation in Flutter is nothing but adding or removing pages or screens by stacking new pages of existing ones. If the developer has to move to a new screen, the current screen might push into the navigation stack.
When you return to the top screen it pops off the stack immediately. So, this type of navigation is mainly useful for hierarchical and linear flows within app design and development.
What is tab navigation?
Of course, tabs are a staple in the design or development of mobile app navigation. Hence, it allows users to find out switches and enable them to focus on the current context. The flutter makes it easy to find tabbed navigation within built-in widgets such as TabBar, and TabBarView.
They are integrating into the beautiful and functional tab navigation experience. It is mainly perfect for organizing content into logical sections. You have to create a unique look and design for your app.
What is drawer navigation?
The drawer navigation is nothing but a pattern which includes a hamburger menu or side menu. It is a familiar navigation style which includes the design and development of mobile apps.
It consists of hidden panels which slide out with the screen or reveal the menu with dynamic navigation options. Hence, it consists of a space-saving technique which is visible and provides easy access.
How to build the tab navigation
Of course, flutter app design and development using drawer and tab navigations are found at the top. Developers have to press the button in the first tab and take them to the next page via the stack navigator.
Tab navigation in flutter
Creating a class named HomePage has to be embedded in the build method and returned with the default tab controller widget. It has to take part in defining the 3 tabs in the lengthy property. In the bottom appBar property, users have to define icons for each tab with the body property rendering all the tabs inside it.
Then, immediately paste the code and notice if some errors may be highlighted in the VS code editor.
Create a new folder named the tabs inside the lib/directory and create the files named tab1 to tab3 in the list
If you look at the code for three navigation types you will notice the same except for the first tab and the rest continue with an additional button to disclose secrets. Then, it has to press the navigation user with the secret route as well. It will work for any error and the route must be defined yet.
The errors may be seen in the tab. dart file which sets out the resolved condition. The app must be noticed with changes in the execution time. It is because of creating a tab layout and mapping it with the main. dart file as well.

In the section, don’t need to press the disclose secret button. If you press it, it shows an error and makes changes before executing the output. The navigation route should be on the press property with a button and the route is yet to be maintained secretly.
How to build the drawer navigation
The next target is to add the drawer navigation and create the files with navigation types.
drawer. dart: to show the Navigation Drawer
. dart: an option will be provided on the Drawer Navigator to navigate here
On the other hand, creating a drawer.dart file inside the library and directory has to bring touch with further results and done with tabs. Then, you have to copy the code into the drawer. dart file.
drawer. dart file
In this file, developers have to define the right class and name MyDrawer. It is helpful for them to build a method which renders the drawer widget with home and about options in the lists. Then, developers have to choose options which navigate with appropriate routes.
about. dart file
In this file, the developer has to create a class named “About” and return the scaffold widget which contains a drawer. It will define the right code before this file usage. The appBar and the body will show in the text about code again to make changes in the app design. It is because we could retrieve or link into the main. dart file.
secret. dart file
In this file, the developer has to create SecretPage and return with a text in the body. Of course, users have to identify the simple flutter widget and backlog in the above procedure. It is mainly set out defining routes now. Then, it makes sure to obtain the main. dart file and follow the importing method to the top of the file.
Update in main.dart file
By following the code, you have to check to define the MaterialApp to contain routes. It will assign key-value pairs and be able to map routes with a widget. Coders have to navigate with three routes and find key-value pairs.
/about – the route for the drawer navigator
/home – the route for the tab navigator
/secret – the route for the stack navigator
Merged tab and drawer view
By pressing the disclose secret button, you will be taken to the secret page which was created. The developer should be able to scroll with tabs smoothly and notice with an error-free execution. The back button is shown on the first screen and would help to assign navigation bars and styles of your app.
Conclusion
Finally, you will learn about the navigation in Flutter and how to add them in Flutter app design and development. Of course, the flutter web app development brings you more guidance to check and create the navigation in Flutter as well. Most apps must be developed using two or more navigation types.
