FEAT: Extension for Padding Class

[deepraj02]

Description

Added 3 types of Extension Method that deals with Padding for List<Widget> types (Row, Column)

paddingDirectional method provides fine-grained control over directional spacing, allowing you to customize padding for the top, bottom, left, and right sides individually.

paddingSymmetric method simplifies the process of achieving uniform spacing by applying consistent vertical and horizontal padding to each widget in the list.

paddingAll method streamlines layout adjustments by uniformly applying the same padding value to all sides of each widget, ensuring a cohesive and polished design.

Hey, I added some new extension methods also wrote tests for them @AbhishekDoshi26

@deepraj02 sorry for the delay, I was busy with the preps of Flutter Conf India.

I don't get the use-case of this extension. I mean, if I want to give padding to each element of my column/row, I will just give the padding to the column instead of giving to each element. As per your code that I understood, it is giving padding (only, symmetric and all) to the elements of List<Widget>.

Can you explain the use-case of the same?

@deepraj02 can you update me on this?
