Set width and height for Cupertino Picker

Cupertino Picker in flutter takes 100% width.

How do we give it custom styling? Height, Width, Borders?

I tried putting it inside a container with width and all, didn't work.Instead there was a weird soft edged background when I gave container a color.

Answering my own question for the time being,

I got a workaround by making the following tree:

• Row

  • Sized box(width:20)

  • Expanded

    • Cupertino Picker

  • Sized Box(width: 20)

I tried multiple workarounds but none worked

A better approach is highly appreciated!
