side property Null safety
final
The color and width of the checkbox's border.
This property can be a MaterialStateBorderSide that can specify different border color and widths depending on the checkbox's state.
Resolves in the following states:
- MaterialState.pressed.
- MaterialState.selected.
- MaterialState.hovered.
- MaterialState.focused.
- MaterialState.disabled.
If this property is not a MaterialStateBorderSide and it is non-null, then it is only rendered when the checkbox's value is false. The difference in interpretation is for backwards compatibility.
If specified, overrides the default value of Checkbox.side.
