LiquidButton constructor Null safety

LiquidButton(
  1. {required String name,
  2. double fontSize = 19,
  3. double width = 88,
  4. double height = 36,
  5. required dynamic onPressed(
      ),
    1. Color? backgroundColor,
    2. Key? key}
    )

    The only required fields are name and onPressed

    Implementation

    LiquidButton(
        {required this.name,
        this.fontSize = 19,
        this.width = 88,
        this.height = 36,
        required this.onPressed,
        this.backgroundColor,
        this.key});
