This is a Jetpack Compose full-screen dialog design. It shows a “Congratulations! you have won a medal” message with an image.
The dialog is made with composables like Surface, Column, Icon, Text, and Button. The Surface needs a child which is the Column. I put everything inside the Column. Its children are arranged at the center both vertically and horizontally. There is a 20.dp gap between the children.
The Jetpack Compose full-screen dialog composable takes two parameters – primaryColor and context. The primaryColor is applied to the icon and the button. The context is useful for displaying the toast message. You can adjust the values according to your requirements.
The dialog’s state is managed by the variable called dialogOpen. Initially, it is false which means the dialog is closed. When you tap on the “OPEN DIALOG” button, its value becomes true and the full-screen dialog will show up. The Dialog composable is placed in an if condition. To make the dialog full screen, you need to use the usePlatformDefaultWidth parameter from the DialogProperties Class. Set it to false, and the dialog occupies the whole screen.
Before downloading the source code, make sure that you are using the latest version of the Android Studio. Jetpack Compose doesn’t work in the older versions.
