Containers

In Flutter, a container widget is a rectangular box that can be used to contain other widgets. It allows you to customize its appearances, such as setting its background color, border, padding, and margin.

The container widget is very versatile and can be used for various purposes, such as creating buttons, images, text boxes, and more. It also allows you to add child widgets inside it, which makes it easy to create complex layouts.
