global_focal_point: Offset = field(
    metadata={"data_field": "gfp"}
)

local_focal_point: Offset = field(
    metadata={"data_field": "lfp"}
)

The initial focal point of the pointers in contact with the screen, in local coordinates.

pointer_count class-attribute instance-attribute

pointer_count: int = field(metadata={'data_field': 'pc'})

The number of pointers being tracked by the gesture recognizer.

Typically this is the number of fingers being used to pan the control using the gesture recognizer.
