I want to create a calendar interface with Flutter, but I can't figure out a way to make a ListView.builder that is infinite and can scroll both up (to previous dates) and down (to forward dates).
You can see it in the Google calendar app where you start it and you can scroll up and down through the calendar, with the starting point being the current date.
There is a ready-to-use package that provides that functionality
https://pub.dartlang.org/packages/infinite_listview
If you want to build your own the source is available.

I am attempting to create a androidx.constraintlayout.helper.widget.Carousel in Xamarin.Android. I have looked at the following:
https://developer.android.com/develop/ui/views/animations/motionlayout/carousel
However, this was not extremely useful because it is not in C# or for Xamarin.Android. I was also somewhat unsure what to do for the adapter, since Carousel.Adapter doesn't seem to exist, and Carousel.IAdapter requires implementing multiple methods other than the ones mentioned. I would like to be able to see a complete example or tutorial for Xamarin.Android. I have never used MotionLayout or Carousel, although I have used RecyclerView many times (Carousel.Adapter looked similar to RecyclerView.Adapter, just with different names). Does anybody know of any good examples or tutorials for Carousel in Xamarin.Android?
According to your description, you can use ViewPager to achieve this function in Xamarin android. ViewPager is a layout manager that lets you implement gestural navigation. Gestural navigation allows the user to swipe left and right to step through pages of data.
For more information, you can check document: Xamarin.Android ViewPager.
And in Xamarin.Forms, you can use Xamarin.Forms CarouselView to achieve this function.
I need a screen to show the time slots for selected date as below. All the data shown here will be taken from database using API calls. I want an similar UI in Angular 7 or later by which I can implement this functionality.
I need help in getting the UI part implemented using Angular for dates to be show in horizontal scroller.
I'm currently in a project which requires a sort of timetable. The requirement is a horizontal (scrollable if needed) week view. Something similar like the iOS calendar when holding the device in landscape position.
I managed to find a couple of Cocoacontrols/-pods, but none of them seem to be working properly or display an actual week calendar. The MSCollectionViewCalendarLayout is similar to what i need but it is unable to compile and it took more time to fix than i'd like to.
Any of you got some quick tips to speed up my project?
I am using Picker for displaying the items,I want to select multiple rows in picker, is there any way to achieve this in Xamarin Forms shared code or through rendering? any suggestion or idea would be much appreciated.
Thanks.
I don't would use Picker for multilselection.
You can do this with a ListView (100% XF-Code).
I have posted some code some time ago in the XF-forum:
http://forums.xamarin.com/discussion/17885/multiselect-listviews
If you have to show the "Multiselect-ListView" from a ScrollView, you may also be interested to use the PopUp-Control (XLabs):
https://forums.xamarin.com/discussion/33587/how-to-use-a-listview-in-a-scrollview-with-xlabs-popup-control#latest
And finally, if you want to install the XLabs-NuGet, a further posting to XLabs may help you (search for "How to install, setup and use XLabs" in the XF-forum).
As i don't have more than 10 rep-points here, I am not able to post more then two links :-)
Hope this helps...
No there isn't.
The Picker Class, has SelectedIndex property, but no SelectedItems collection. Also, the native control under the hood on iOS doesn't support selecting multiple rows and I don't think the Android or Windows one do either.
You could create use a Custom Renderer if there was a native control you wanted to use. But, it would probably be easier to use a ListView control and add some events and style it to look and behave like you want.
i have a calenderUi.
