Enum PanEvent 

pub enum PanEvent {
    Start {
        local: Point,
    },
    Update {
        local: Point,
        delta: Point,
    },
    End {
        velocity: Point,
    },
}

One moment of a drag on a GestureDetector, as the shell reports it through Widget::on_pan.

Variants

Start

The drag began: the pointer went down at local (in the detector’s own coordinates) and has since moved far enough to be a drag rather than a tap.

Fields

local: Point

Where the pointer went down.

Update

The pointer moved by delta and is now at local. Along a PanAxis that is not free, the other component of delta is zero.

Fields

local: Point

Where the pointer is now, in the detector’s own coordinates.

delta: Point

How far it moved since the last update, in logical pixels.

End

The pointer lifted, moving at velocity (logical pixels per second).

Fields

velocity: Point

The release velocity, masked to the axis like the updates.
