Problem to solve

With Row and Column classes children Components could be placed and layouted correctly without overlapping and without having to care about repeating size and position calculations.
In my games i often have Components (Sprites, buttons, etc.) which have to be placed either in rows or columns, where it's always quite an effort to calculate their positions and sizes.
The goal of the suggested two classes would be to make these calculations transparent for the developer.

Proposal

Flutter-like Row and Column classes with alignment options for both axes (i.e. mainAxisAlignment and crossAxisAlignment).
Some ideas:

• the new classes could extend PositionComponent themselves
• children can possibly be all PositionComponent extending classes (since getting their size is important)
• adding a child dynamically to a Row or Column would need to re-layout the component
• another new class for adding gaps would make sense too (like SizedBox) - ok this can be accomplished by just adding a PositionComponent with a size defined
