Column Layout

Arrangements and Alignments 

To set positions of items within a column, we can use verticalArrangement and horizontalAlignment arguments. Similarly, to set positions within a Row, we have the horizontalArrangement and verticalAlignment arguments.

Vertical Arrangements.

There are 6 vertical arrangements.

• Center
• Top
• Bottom
• SpcaeEvenly
• SpaceAround
• SpaceBetween

Horizontal Alignments

There are 3 horizontal alignments.

• CenterHorizontally
• Start
• End

Vertical Arrangement and Horizontal Alignment.

we are going to use both arrangement and alignment together.
