padding property
Padding around the content of the sheet.
When expandable is true and useSafeArea is true, the sheet merges the relevant safe-area insets into this padding before passing it to the underlying ShadDialog. This lets the sheet background cover the notch / home-indicator while the content stays inset; widget inspectors that read the dialog's padding at runtime will see the merged value, not the raw value set here.
Implementation
final EdgeInsetsGeometry? padding;
