IntrinsicWidth

It adjusts to its content inside (Width).

The IntrinsicWidth widget in Flutter is similar to the IntrinsicHeight widget, but instead of adjusting to the height of your content, it adjusts to the width of the content. This can be useful in cases where you want to ensure that a widget has the same width as its content, and changes dynamically if the content changes size.
