Which widget should be used to arrange children horizontally in Flutter?
Risposta
Row is the fundamental widget for arranging children horizontally along the main axis. It respects its parent's constraints and distributes space according to mainAxisAlignment and crossAxisAlignment properties. For vertical layouts, Column is the equivalent.

Which Row or Column property controls the distribution of children along the main axis?
Risposta
mainAxisAlignment controls how children are positioned along the main axis (horizontal for Row, vertical for Column). Options include start, center, end, spaceBetween, spaceAround, and spaceEvenly. crossAxisAlignment controls positioning on the perpendicular axis.

Expanded forces its child to fill all available space (fit: FlexFit.tight), while Flexible allows the child to take the space it needs up to the maximum available (fit: FlexFit.loose by default). Expanded is actually a Flexible with fit: FlexFit.tight.
