Time range picker

I would like to build this google calendar’s timeslot-picker but unfortunately, there is unfortunately no similar online tutos or blogs explainging so. I have no single idea how to start it. Anyone can give me some hints which Flutter widgets I need to use to build it?
It also has two dots to make the timeslot longer or shorter..
I appreciate your help.

How to add our own gestures in android?

I am working on the gestures concept. I want know some thing about how to add our own gestures in android.For example if user drawn "O" symbol i want to make some events. Please share some tutorials and Snippet of the code.

There are quite a few results available with a relatively simple Google search. I would normally post a sarcastic comment or something. :-)
But this isn't quite an everyday subject if you would, so I have here a few links that should get you started. But you should work on your Google foo too. ;-)

I found the 5th link a little more promising. Of course, I haven't seen too much of it for that to be definite. But try them all anyway.

Check the link below which will guide on how to create our own gestures and use it.
1) Link 1
2) Link 2
3) Link 3
4) Link 4
Go throug some of the links you will surely get some idea about gestures.

Implement Calendar into Android App

Is there any way I can implement Androids Calendar app into an app I am making? I would like to have it so i can switch between Month view and week view just like in the calendar app. Do I have to code this all or does google provide something to help me do this?

As far as I know, you have to implement it yourself.
But don't forget Android is open-source, you can always look at the Calendar source code and reuse it.

Replicating the iOS time picker in Android

I'm trying to write an app that would use the timepicker in Android, but I really would like to implement the one from iOS.
I've had a couple of leads, but haven't struck anything that has worked for me.
My problem is that the time picker is for time but I want to use mine for three different number values that can be chosen (no am/pm) so it seems like Pickers are the way to go, except that they were introduced in API 11.
I've found this blog that seems to give you some code for it, but I wasn't able to get it to work.
I also found android-wheel, but I don't know how to get the source for it. Can anyone steer me in the right direction for it?
The iOS timepicker looks like this:
Android wheel looks like this:
But, I haven't been able to figure out how to get the code for it.

The code is in the google code project - https://code.google.com/p/android-wheel/source/browse/

Download the source code from below link for various wheel example:
http://android-wheel.googlecode.com/svn/trunk/
Make sure that you have the svn plugins for download.
Thanks.

Android - Show events by hour in calendarView?

I've been looking to make a calendar that will show events like the following picture below in android. Can this be done with CalendarView? What is the best way to go about this?
I hope this isn't a duplicate, i looked through stackoverflow for a similar answer but there was no good starting point for calendarViews. Thank you for looking.

Have you look around this library?
