ExpandedGap class
A custom version of the Flexible widget that represents an expanded space within a flex_gap layout.
ExpandedGap is a convenience widget to simplify the addition of an expanded space in a flex_gap layout.
It inherits from the Flexible widget with a FlexFit.tight configuration and a flex value of 1.
This results in the child (or an empty Offstage widget by default) expanding to fill available space.
Advantages of using ExpandedGap:
- Simplicity: Provides a concise way to create an expanded space within a flex_gap layout.
- Configurability: Inherits the flexibility of the Flexible widget, allowing for customization of fit and flex parameters.
- flex_gap Integration: Seamlessly integrates with the flex_gap layout for a consistent spacing solution.
