onShove method
Called when a two-pointer shove gesture occurs.
A shove occurs when two pointers move while keeping their spacing and relative angle within thresholds.
Parameters
pointersAngleDeg: Angle between pointers in degrees.initial: Midpoint at initial touch down.start: Midpoint at previous update.end: Midpoint at current update.
Implementation
@override
void onShove(
final double pointersAngleDeg,
final Point<int> initial,
final Point<int> start,
final Point<int> end,
) {
_shoveCallback?.call(pointersAngleDeg, initial, start, end);
}
