Gesturedetector: onLongPressStart Details flutter

I'm trying to record a video when a button is pressed long (in flutter)

This is my code:

GestureDetector(
                    onLongPressStart: () {print("START VIDEO");}
                    onLongPressEnd: () {print("END VIDEO");}
                    onTap: () {print("take photo");},
                    child: Container(
                      width: 40,
                      height: 40,
                      color: Colors.red,
                      child: Text("BUTTON"),
                    ),
                  ),

But it gives an error:

... can't be assigned to the parameter type 'void Function(LongPressEndDetails)'.

What is LongPressEndDetails?

onLongPressStart requires you to pass LongPressStartDetails , so

Instead of 

onLongPressStart: () {...}

use 

onLongPressStart: (LongPressStartDetails details) {...}

or simply

onLongPressStart: (details) {...}

Tried this and it's working...

onLongPress: () {
        print('start recording');
    },
    onLongPressUp: () {
        print('stop recording');
    },
