I'm developing a flutter web application using https://pub.dev/packages/flutter_map, to load some shapes in geojson format. Everything is fine when the user zooms in or out, but when trying to pan the map (panning behavior), it doesn't seem to move until I zoom again.
Any helps?
Thanks.

I am searching for a way to implement this and So far I have reached nowhere. The Exact thing that I meant by animating a polyline is an uber-like animation. Things I have thought of is building each coordinate of routes using a loop and a timer. But it rather seems to be expensive, another thought is just to plot a simple curved line using canvas from one point to another (also hypothetical). In Android, it is achieved by using overlays, and flutter only supports tile overlays.
Hope you are fine.
I have trouble with the following:
Currently I try to expand the background of my app while using the pan gesture. To be more specific, the user should be able to “pan” to the right/left and the app “smoothly” displays the expanded or new background.
To visualise it look at the following example gif, please:
The background is a SKSpriteNode and I thought it is possible by using cameraNode or anchorPoint. But I don’t get it to work. After finding myself on Google page 23 I started to get desperate. Probably I’m using the wrong terms for the search.
I’m only able to show a new scene or the full “new” background. And that’s not what I want.
Thanks for any feedback!
i am using cordova-plugin-googlemaps(1.4.1) in ionic(3.4.0) and i am looking for a way to rotate the map with one finger.The plugin's documentation doesn't have any events for drag.
I found some custom code for android here How can I rotate on Google Maps API(android) with only 1 finger? but i am not very familiar with java, i'll still be missing IOS functionality and this means i have to modify base plugin(i think). So I need something for Ionic's google maps plugin.
Thanks!
As a console app, I'm creating maps with Bing Maps, with lat/lon and pushpins. Saving as a jpg. Everything is working great. NOW, however, I'd like to draw a polygon layered on said map[s]. It seems this might not be possible; I cannot find the answer. Dynamic via web page it seems is the only way; I need it to happen with a console app.
The custom polygon as well as custom polyline are not supported features on the REST service.
Since you're in a console application and as you're saving the image as JPG file, you can draw your own content onto the image using GDI or other technology to manipulate the image directly. Currently, there is no other way.
I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps.
Am I missing something here, but can this be done with a none standard map and having different zoom levels?
The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.
Georeferencing is how you "pin" your image to the world. It is a tricky process, but not too hard once you dig into it.
You've already found the TileMap example code - that is the first step.
Next, check out MapTiler.org. There you will find links and some binaries that you can use to process your image into georeferenced tiles.
If you don't know the lat/long coordinates for your image, you can use Google Earth to interactively overlay the image onto the map, and then copy the coordinates out.
Good luck!
