The lines to separate the action buttons are blurry.

In cupertiono/dialog.dart the dividerThickness is callculated this way:

dividerThickness: _kDividerThickness / MediaQuery.of(context).devicePixelRatio

But do we need the devicePixelRatio to do so? When I just use dividerThickness: _kDividerThickness the lines are perfect.

On the left side, you can see the divider with dividerThickness: _kDividerThickness / MediaQuery.of(context).devicePixelRatio.
On the right side, you can see the divider with dividerThickness: _kDividerThickness.
