Wrong horizontal child position with extended FAB

[deakjahn]

If we have a label wider than the activeLabel, the position of the children will be wrong. They appear correctly aligned to the right of the FAB when the label doesn't change, but when is switches to the shorter active label, the children will retain their position relative to the left, meaning that they will be shifted out of the screen on the right. Just try:

SpeedDial(
  icon: Icons.add,
  activeIcon: Icons.close,
  label: Text('a text longer than the next one'),
  activeLabel: Text('short'),
