MainAxisAlignment in Flutter describes how child widgets should be laid out along the main axis within a parent Column or Row widget. It offers values like start, end, center, and spaceBetween, among others, to define the positioning and spacing of widgets.

- Column Widget: The
Columnserves as the parent container for our widgets.

- Spacer: This widget takes up all available space, pushing the widgets that come after it to the bottom.
- Column: It serves as the parent container for our widgets, including the
Aligning widgets at the bottom of a column in Flutter can be done in various ways. Each has its pros and cons.

Spacer is dynamic, and custom
Padding gives you the most control. Depending on your project’s needs, you can choose the best method for you.
