Expand description
A force description of a Touch
input.

Fields
force: f64
The force of the touch, where a value of 1.0 represents the force of an average touch (predetermined by the system, not user-specific).
The force reported by Apple Pencil is measured along the axis of the
pencil. If you want a force perpendicular to the device, you need to
calculate this value using the altitude_angle
value.
max_possible_force: f64
The maximum possible force for a touch.
The value of this field is sufficiently high to provide a wide
dynamic range for values of the force
field.
On iOS, the force is calibrated so that the same number corresponds to roughly the same amount of pressure on the screen regardless of the device.
Normalized(f64)
If the platform reports the force as normalized, we have no way of knowing how much pressure 1.0 corresponds to – we know it’s the maximum amount of force, but as to how much force, you might either have to press really hard, or not hard at all, depending on the device.
