A drawer is an invisible side screen which generally contain menu items and occupies around half of the screen when displayed.
Here is how the code for basic MaterialApp shall look like. The DWidget here is the widget which will contain drawers. It should be noted that drawers are part of Scaffold along with appBar and body. Once we add drawer to the Scaffold, it generates a three line menu item on the top left corner of the application bar, which on clicking displays the drawer screen.
Here is how the basic code shall look like. This will create an app with a bare minimum drawer as displayed below. As you might have noticed that drawer, takes child: and not children:which means at any point of time we can have only one widget inside drawer. To have more than one widget, we need to use widgets which are capable of holding multiple child widgets like Column. Here is how the drawer code will look with Column.
This will display three lines of text in the drawer. Now we know what drawers are and how it can be created. In flutter, we can create a similar header using DrawerHeader widget which takes a child and allows us to decorate the header.

Here is how the code with DrawerHeader shall look like. And here is how the existing drawer changes. This happens because within the drawer childwe only have DrawerHeader and nothing else. To move the drawer header on top of the drawer, we need to use the widgets which can contain multiple widgets e.
Here is how we can use the ListView inside the Drawer. And here is how the resulting app shall look like. Now, this is what we were looking for. This also resembles the apps like GMail and Twitter drawer header. Now, we can decorate the header the way we want and have as many items and links as possible. Since we want some actions to be performed when someone selects or taps one the items of the drawer, we need to use widgets which can handle onTap method, or alternatively we need to create a container around widgets to handle gestures.
However, using widgets with in-built onTap handler is preferred over here because of its ease of use. One such widget which we can use inside the ListView is ListTile.
Here is how the complete drawer code shall look like. And here is how the actions will look like on the app. This can be achieved by unloading the drawer before we load a new page by calling Navigator.
Here is how the onTap code shall be changed. And the resultant screen will not keep the drawers on the original Page. We generally create common actions on drawers which which should be made available across the whole application. This can be done by making sure that the drawers are available to each Scaffold or all the pages.
This effectively means that we can have drawer code in a separate stateless widget as.This is a flutter navigation drawer tutorial with a full example.
We start by discussing what navigation drawer is, when to use then look at a full example with fragments containing gridviews.
A NavigationDrawer is a widget that allows us render navigation items in a sidebar with an optional user account profile. It usually has a header where we can display user account details like name, email, profile avatar et. When a single navigation drawer item is clicked you navigate to a page or what we are calling fragments in this case. Use navigation drawer when you have more items than can fit comfortably in a tabbar or bottomnavigation.
Or if you find navigation drawer more intuitive to use of course. We will explore an example where we will render a navigation drawer with header containing user name, email as well as avatar.
Flutter 1: Navigation Drawer & Routes
We will show a user image as avatar. We will also show a navigation drawer background image. Then when the user clicks a single navigation drawer item we will open an associated fragment or page.
That fragment will contain gridviews with some data. Download the source code here.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'm trying to do what I think is a very simple Flutter app, but I can't figure out what's going wrong with my code. I have a Flutter app with a Drawer widget. Since the main page of the app MyHomePage extends from StatefulWidget the only thing that I do to load a new view is to call the setState method to assign the new value of my "control variable" viewNamethen I expect that Flutter executes the Widget build BuildContext context method of MyHomePage but with the new value of viewName this time.
All of the above works as expected, the problem with this is that in the body field of the Scaffold I have a TabBarView widget, since I want to show to the user a view with two tabs Tab 1 and Tab 2 per each view A, B and C.
What I want to demonstrate here is that when you tap an option of the Drawer Load the B view for example the Tab 2 changes as a expected it's value, but the Tab 1 that contains a stateful widget not changes it's value when you tap any other option of the Drawer.
Note: I must use the same StatefulTab widget for the 3 views in order to reuse the code, since the only value which changes for the 3 views is the viewName variable. How can I tell Flutter that takes the new value for the stateful wdiget of the Tab 1? I think I found your problem. This can't really work, because for the StatefulTab the state doesn't change only because the state of the HomePage changes. I came to that conclusion by inserting print statements in the two build methods.
The build method of the HomePage acts according to your desired behaviour as you already saw in the header of the scaffoldbut the build method of the StatefulTab kept its state. Further investigating and various print statements in various places led me to the conclusion, that the constructor of the StatefulTabState is not called after one of the drawer buttons is clicked.
Here is a working example of your StatefulTab:. Don't hesitate to comment, if you have any questions. For implement TabBar and drawer flutter provide us following widget. TabController 2. TabBar 3. I found a simple demo of TabBar and drawer.

I will check the tutorial that you mention, since in effect, I have not followed it yet and it seems very didactic. Thank you very much!This article explains how to navigate using drawer in Android and iOS using Flutter as the framework and Dart as the language.
In this post, we will learn how to navigate from one page to another using drawer menu options. As we all know, the app is just a widget in Flutter or a description of the UI portrayed. Each class which we create by extending StatelessWidget class gives us the ability to describe the part of our UI by building a constellation of another widget that describes our User Interface more loosely coupled.
So, the example which I will be implementing here is going to have one drawer to the top left of the screen on the app bar, which will have some menus. These menus will open UI respectively on user click. See if Doctor command runs without issue. You will see the 'Flutter: New Project' command suggested in search, Like Below: It will ask you to give the name for your project.
Make sure you have your Emulator setup done. Start your emulator. Now, we must make changes in our Main. Dart code file. Find this file in the project which we have just created. Second is Text for the menu and third is Action for an event onTab.
Inside this CustomListTile class, we have implemented our menu. We have a rectangular area which responds to our touch on the UI element. So, Splash is the grayed animated background which gets enable when we touch our UI Element, especially it happens with buttons.
Now, we will add our two views: ProfileView and NotificationView. Add these views in our main. Both classes are using the same Drawer which we have assigned using InkwellDrawer function to drawer object.
InkWell is our class which we have used earlier for implementing our drawer. It is good to have drawer object to be the same drawer to make drawer available in all views. For Clipper, we have one more class for customizing our clipper which we are doing in ClippingClass. You can remove that to have nothing on your home page or you can keep that.Scaffold in Flutter is a very useful and highly flexible class. In Flutter, Scaffold implements the basic material design layout structure.
The developer can implement a wide range of widgets using Scaffold as the Parent Widget. In this tutorial, we will see how to create a Scaffold and also see some of the most useful Constructors. Scaffold, like the name suggests, creates a visual scaffold for material design widget.
The most commonly used Widget, Scaffold can complete the entire App building with its flexible properties and attributes. In order to implement a Scaffold in Flutter, there is some additional information required to be known. The rest of the article explains everything in depth with examples. Before we jump on to create a scaffold widget, we will understand how the Scaffold creates a visually better Material design standard layout in a matter of seconds. See the below image for better understanding of what the Scaffold Widget offers.
As an Android developer, we use activities for single screen representation which consists of many views like toolbar, menus, drawer, bottom navigation bar, snack bar, float action button etc. All of this can be flexibly added using a Scaffold. Flutter Consists of a lot of Widgets Flutter is all about widgets onlyScaffold, in particular, handles the following Widgets in it. That is, it is capable of packing all the widgets into it. They are. To know more about Widgets that Scaffold has to offer, we will see some of the important properties of the Scaffold class.
This is a sample Background Color attribute like any other widget. An example of that is given below. The primary content of the scaffold.
We can create any widget to be held here. A sample is provided in the application example in the next section. A bottom navigation bar to display at the bottom of the scaffold.Another option is to try pptp vpn
BottomNavigationBar is used to provide a Navigation-like bar in the bottom of the App.We are parsing JSON document that performs an expensive computation in the background. Add this package to the dependencies section of our pubspec. If we run the fetchPosts function on a slower phone, the App may freeze for a moment when it parses and converts the JSON.
This function runs parsePosts in a background isolate and return the result. In order to display fetched data on screen, we can use the FutureBuilder widget with two parameters: — The Future to work with. In our case, the return of fetchPosts function.Mobile legend offline 3v3
