Not able to get Date of Birth of the sample form to stick

[yokiran]

I'm on 1.4.0 on Android. Once I select the Date of Birth, it displays momentarily until the keyboard comes up and then the date vanishes. Similar issue with the Appointment Time. Also getting the render issue below when the keyboard is active and Date or Time widget is displayed.

I/flutter (19904): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
I/flutter (19904): The following message was thrown during layout:
I/flutter (19904): A RenderFlex overflowed by 46 pixels on the right.
I/flutter (19904):
I/flutter (19904): The overflowing RenderFlex has an orientation of Axis.horizontal.
I/flutter (19904): The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
I/flutter (19904): black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
I/flutter (19904): Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
I/flutter (19904): RenderFlex to fit within the available space instead of being sized to their natural size.
I/flutter (19904): This is considered an error condition because it indicates that there is content that cannot be
I/flutter (19904): seen. If the content is legitimately bigger than the available space, consider clipping it with a
I/flutter (19904): ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
I/flutter (19904): like a ListView.
