So, in the incrementCounter method (which is called when the button is pressed) add this line: Provider.of(context, listen: false).
On each button click we need to increment the counter value by 1. I am trying to use the Provider state management 'cause I'm trying to learn while I'm creating some apps. With this done, we can now use the provider pattern in Flutter to set and get the counter value. I'm trying to change the content of the body property of the Scaffold widget dynamically based on what the user clicked on the bottomNavigationBar. will contain another Navigator to fit your purpose.I'm new to flutter and in need of help with this project I'm working on. Page index 1,2 and 3 will be inside the root Navigator under material app. I only got this when, for example, I wrap the index of page 2 in materialApp. The body property is typically a such as a. You can try to use nested Navigator inside your scaffold. I am trying to go to the next page using Navigator.push and at the same time change only the body on the page. In Flutter, the body property of a Scaffold widget is used to specify the content that should be displayed in the main screen of the app. Using a Navigator for these kind of subpages inside a body is a bit more tricky than using different scaffolds. And the body at this moment is replaced with the old page with a smooth movement, I really like it and I want to do the same. To create a local project with this code sample, run: flutter create -samplematerial.Scaffold.1 mysample. The easiest way is this, but then you dont have any backbutton control cause you are not using a Navigator. In many applications, I see such an animation that the header fades out smoothly and at the same time a new one appears. I gave a picture of how I am currently navigating in the application, it may not be perfect, but I do not know better, any help would be appreciated. At the moment, I have no idea how to remove a fixed page. I understood this in such a way that the first deleted page was an index 2 page, which is wrapped in MaterialApp, and behind it is exactly the same fixed MaterialApp for the entire application. We are going to overview itâs parameters one by one. Have a look at its constructor and the properties it has. It provides APIs for showing drawers, snack bars and bottom sheets. The function argument to setState increments the counter variable. This method call tells Flutter that a state inside a widget has changed, and the widget has to be redrawn. It is useful to define a particular thing as its own widget instead of just as a method that returns a. You can define your own stateless and stateful widgets by extending StatelessWidget or StatefulWidget. The incrementCounter function calls setState when the button is pressed. If you want to just setState within the body of the scaffold, make the body a stateful widget and call setState within that widget. But when I decided to make the animation (it smoothly pushes the old page to the left and pushes the new page to the right), it turned out that she pushed the old page, but behind it was exactly the same motionless page, which was later blocked by the new one. A Scaffold Widget provides a framework which implements the basic material design visual layout structure of the flutter app. The button has an onPressed event set to it, similar to onclick event in HTML. I am trying to go to the next page using Navigator.push and at the same time change only the body on the page.
