MyContainer class

A customized Container widget that wraps the standard Container.

Provides convenient parameters for padding, margin, color, alignment, and common BoxDecoration properties like borderRadius, border, boxShadow, gradient, etc. Allows for full customization by passing a custom Decoration.

The color property is always applied as part of the decoration. If a decoration is provided and it is NOT a BoxDecoration, the exposed BoxDecoration properties (like color, border, etc.) will be ignored.
