How about this one.

From this your code,

Padding(
  padding: EdgeInsets.only(right: 10),
  child: IconButton(
    icon: Icon(Icons.play_circle_fill_outlined, size: 45),
    onPressed: () {},
    color: light_mode ? Color(0xFFEA80FC) : Color(0xFF6D6D6D),
  ),
),

to this one.

SizedBox(
  width: 36,
  height: 36,
  child: FloatingActionButton(
    onPressed: () {},
    backgroundColor:
        light_mode ? Color(0xFFEA80FC) : Color(0xFF6D6D6D),
    child: Icon(Icons.play_arrow),
  ),
),
