[Solved] Error: Too few positional arguments: 1 required, 0 given

You don’t need to specify the parameter label for BottomTabBtn. Instead of:

BottomTabBtn(imagePath: "assets/images/tab_home.png"),

Use:

BottomTabBtn("assets/images/tab_home.png"),

If you really want to use parameter label, then change your constructor declaration to:

BottomTabBtn({this.imagePath});
