fixedSize property Null safety

MaterialStateProperty<Size?>? fixedSize

The button's size.

This size is still constrained by the style's minimumSize and maximumSize. Fixed size dimensions whose value is double.infinity are ignored.

To specify buttons with a fixed width and the default height use fixedSize: Size.fromWidth(320). Similarly, to specify a fixed height and the default width use fixedSize: Size.fromHeight(100).


final MaterialStateProperty<Size?>? fixedSize;
