And the body of the app is blank currently. The green color in the appbar is provided the be backgroundColor property, the menu icon is provided by the leading property, the text ‘GeeksforGeeks’ is provided by the title property and at the right corner the action parameter is holding note icon and a Si zedBox (to provide gap from the debug banner). Then inside the Scaffold widget, we have AppBar widget which is occupying the appBar parameter. In the home parameter of the MaterialApp class, we have a Scaffold widget that basically provides the whole screen of the device to render app widgets. After initializing the app we have the MaterialApp class which is going to hold the entire widget tree for the application. It customizes all the typography belonging to that category.Įxplanation: In the main.dart file the first thing that we did is we imported the material design library which is going let us use material design widget which in this case are MaterialApp, Scaffold, and Appbar. So changing attributes like typeface style, size, and spacing causes a ripple effect. For example, the text on a button belongs to the button category, which is shared by the buttons in a dialog box and tab labels. Each component’s typography fits into a category. Type is one of the subsystems that allows you to theme Material components, customizing them to create something unique. Working out a good type scale for your app keeps typography consistent and significant to users, while providing enough stylistic options to create a compelling appearances and character. The Material type scale is a mixture of 13 reusable styles that each have an intended application and meaning, all the way from big headline styles to body text captions and buttons.

On colors are useful because they can help ensure that content appearing in various contexts throughout your app remains consistent and readable. For example, the on background color for the below app is black, because the text that appears on the background is black, as well as other elements like icons.
