Curves have no effect using leftToRight transition type?

[mattf80]

Running flutter 2.0.1

Steps to reproduce:

1. Create new Flutter project
2. Copy and paste example from the docs into main.dart
3. Add a curve to one of the transitions:

    ElevatedButton(
              child: Text('Left To Right Transition Second Page'),
              onPressed: () {
                Navigator.push(
                  context,
                  PageTransition(
                    type: PageTransitionType.leftToRight,
                    curve: Curves.easeInCubic,
                    duration: Duration(milliseconds: 500),
                    child: SecondPage(),
                  ),
                );
              },
            ),

Expected behaviour: Page transition adapts to the curve provided

Actual behaviour: No curve or effect at all is applied, the page just slides in

I thought I was missing something (and I probably am!) but given that this is a direct clone of the docs example, was wondering if I can ask for a little help? Thanks,

Exploring the examples a bit more, it seems like the curves don't take effect if using PageTransitionType.leftToRight but they do if using PageTransitionType.leftToRightJoined - is that right?

You can use both of them

It seems like this issue isn't resolved. Using PageTransitionType.leftToRight or PageTransitionType.rightToLeft causes the curve property to be ignored. Setting it to PageTransitionType.leftToRightJoined or PageTransitionType.rightToLeftJoined fixes this and the curve is once again respected.
