Jetpack Compose.
The modern Android UI toolkit has revolutionized the way developers create user interfaces.
One of its integral features is the scaffold, which is a powerful tool that simplifies the structuring
of compose user interfaces.
In this video, we'll delve into the scaffold, exploring its components, implementation, and advanced
customization options.
Scaffold acts as a functional and foundational structure for compose user interfaces, providing a layout
that includes essential components like the top app bar, the bottom app bar, and the floating action
button fab.
Its primary purpose is to streamline the development process by offering a standardized layout that
can be easily customized.
Let's explore these components.
Scaffold consists of key components, each serving a distinct purpose.
The top app bar positioned at the top of the UI.
It often contains application, title, navigation, actions, and other relevant items.
The bottom app bar placed at the bottom.
It typically houses navigation icons and other contextual actions.
The Fab Floating Action button A floating circular button for primary user actions, such as adding
a new item or navigating to a critical section of the app scaffold, plays a crucial role in organizing
the UI structure.
It ensures consistency across different screens of the app, making navigation and user interaction
more intuitive by providing a predefined layout, scaffold simplifies the process of creating visually
cohesive and user friendly interfaces.
Now let's jump into Android Studio and start building our scaffold layout.
The current state of our application is this no top app bar, no bottom app bar, or fab.
We're going to use the scaffold in order to add these components.
So the scaffold provides a layout that includes essential components like top app bar, bottom app bar,
and fab.
Inside the Setcontent, I'll start defining a new scaffold.
If we go to the scaffold, we can see the modifier top app bar or top bar, bottom bar.
Snack bar.
Host.
Floating action button.
Floating action button, position container, color content, color content, window inset and content.
We are interested in the top bar, bottom bar, and the floating action button.
Let's start customizing the top bar.
So here inside the scaffold I'm going to specify the top bar.
The top bar is another top app bar.
And here I'll set the title, for example.
Another text top app bar.
The second component is the bottom bar.
So the bottom bar equals to another bottom app bar.
Later in the next videos we're going to deep dive into that top app bar bottom app bar and the fab.
But for now, just for illustrating the usage of the scaffold, we're going to use them like this.
So here the color I'll use the bottom app bar container color equals to.
And the last component is the floating action button.
Here I'll specify another floating action button.
So the floating action button a floating circular button for primary user actions such as adding new
item or navigating to a crucial and critical section of the app.
The button app placed at the button and it typically Houses, navigation icons and other contextual
actions.
The top app bar positions or positioned at the top of the UI.
It often contains app title, navigation, actions and other relevant items.
Now let's run our application.
After specifying the the inside the scaffold, for example my column.
And here we go.
This is our application.
You can see the scaffold that contains my column.
And my column contains three texts.
We can see the top app bar, the top app bar, the title, top app bar title here.
And we can see the bottom bar.
The container color is red and the floating action button which is here.
So congratulations.
This is the scaffold.
The power of implementing scaffold in our applications In the next videos, we're going to deep dive
into the top app bar, the bottom app bar and the floating action button.
