In flutter, how to set spacing between row items inside of a column?

Solution 1:

you can use also

Spacer(), or Spacer(flex: 1),

or use sized box determine your preferred height and width

SizedBox(height: // put here,),

and also sized box have other things like

   SizedBox.expand(),

either ways play with it

If the children of the Row are of fixed size then you can use MainAxisAlignment for Row in order to arrange them accordingly.

Else if you have widgets that are Flexible then you may need to add a SizedBox with the required width between two widgets.
