showPlatformTimePicker function

Future<TimeOfDay?> showPlatformTimePicker({ required BuildContext context, required TimeOfDay initialTime, Widget builder(BuildContext, Widget?)?, bool useRootNavigator = true, TimePickerEntryMode initialEntryMode = TimePickerEntryMode.dial, String? cancelText, String? confirmText, String? helpText, RouteSettings? routeSettings, })

Shows a platform specific time picker with the given initialTime.

On iOS and macOS a CupertinoDatePicker is used. The builder, initialEntryMode, helpText, useRootNavigator and rootSettings parameters are ignored there. On other platforms the Material showTimePicker method is called with the given parameters.
