spacing property Null safety

double spacing
final, inherited

Spacing between the columns. The value ranges from 0 to 1. 1 represents 100% and 0 represents 0% of the available space.

Spacing also affects the width of the column. For example, setting 20% spacing and 100% width renders the column with 80% of total width.

Defaults to 0
