What type of ViewGroup helps arrange the views in a flexible way?

ConstraintLayout is a powerful and flexible ViewGroup that allows developers to create complex layouts with a flat view hierarchy. Unlike other layout types, ConstraintLayout enables the arrangement of UI components in a way that is responsive to different screen sizes and orientations.

One of its key features is the ability to define constraints between views, which means that you can specify how each view is positioned relative to other views and the parent container. This capability allows for dynamic adjustments in the layout, making it easier to adapt to various resolutions and screen sizes without deeply nesting layouts.

Additionally, ConstraintLayout supports guidelines and barriers, which provide additional control over the layout's behavior. This flexibility and efficiency make it an excellent choice for modern Android development, as it simplifies complex UI arrangements while enhancing performance.
