I'm new to Flutter. I want to create a flutter app that show data on the map in the form of cartogram. I just want to render map from geojson file. Is it possible to do that? If it is possible, let me know how to do. Thanks.

Please Help to create this design with slider.
You can use a package like audio_waveforms in flutter.

I haven't tested it. Although it looks like it can do the job.
I am making demo application for experience.
So, the problem is that I am adding list as described in images(Screenshots). But when I add another new list with image so, it automatically changes images at front page in the last and new list both. So, can you guys suggest, how we can get new image in list only once and last list stay the same as we added before.
The code is below.
Thanks in advance.
The problem is you are using the list to add images to the list. As the list is callByReference it will change the value inside the list when the value of the listOfImage is changed.
To fix the issue you can change the addition method to map like
allData.add(Model(listOfImage:List.from(list)));
hope it will work for you if not let me know.
I understand that Flutter routes works like a stack, so I want to know the previous route name which I came from.
I'm using a preview page to show a picture, but this picture can come from the camera or the gallery, I'd like to show a dialog only if it came from gallery.
I read I have to use an observer, but I think there is an easy way to do that.
Thanks in advance.
You can use getx pack to get previous Route
Get.previousRoute;
get current Route
Get.currentRoute;
Well, upon further investigation, there is no way to know the previous page.
I fixed this sending an argument previousPage with the route name value.
You can also use a NavigatorObserver.
i want to show my current location on custom map.The custom map is of my locality....so,please help me how can i use custom map in place of google map???
The main problem with offline maps is not the "map" but all the stuff you need to build to georeference your map.
Think only at a map zoom.
There are many good open source libraries/SDK to manage offline maps.
--EDIT--
It seems that the free code I found was removed.
As soon as I will find a new available one I will update this comment
Hope you all are fine and also in one of your best moods!!

Using the iPhone SDK 3.0 you can use the MKMapKit framework to embed a map in your application, and you can add custom annotations. Here's the MKMapView documentation.
