I want to animate google map from one place to another. I use following code to do this;
final GoogleMapController controller = await _controller.future;
controller.animateCamera(CameraUpdate.newCameraPosition(_endPlace));
The animation works fine. But when I move to the new location the map take some time to load at the new location.
Is there a way to pre load the maps needed along the animation path?
Its not about exactly flutter, but one of technically possible way is to use TileProvider with local preloaded (or loaded in separate threads) tiles files like in this answer. Tiles you can get via URL like that:
http://mt1.google.com/vt/lyrs=m&x=91&y=53&z=7
More about tile coordinates you can find here.
Also read carefully General information and Google Maps Terms of Service especially:
b. copy the content (unless you are otherwise permitted to do so by the
Using Google Maps, Google Earth, and Street View permissions page or
applicable intellectual property law, including "fair use");
c. mass download or create bulk feeds of the content (or let anyone else
do so);
because Google don't allow that. May by OSMDroid is better for you.

for my next project I'm looking for maps, that contains only frontiers of countrys, lakes, hills ans rivers.
Can I get such kind of maps with the OpenStreet-API?
best regards
The "OpenStreetMap API" provides map data, not map images. So, for the imagery you want, you either need to find a source that renders the style you want, or render your own.
I don't know of any services that provide exactly the render that you're looking for. However, it should be very easy to render your own tiles that do this - if you install TileMill and follow through the tutorial, you will find it very easy to delete layers from the default style until no names are included in the style.
Note that if you're planning on running a web service, you'll also need to serve your special new map tiles to your users.
In Google Earth if I have multiple icons that appear in the same location and you click on it, it results in a spider. I would like to override this with a list instead that stays static until you close it.
How would I go about creating this functionality?
You would have to do your own custom clustering, since Earth doesn't expose to you any information about that spider cluster in the API. You'd want, perhaps, to look at the MarkerClusterer utility library for inspiration, but the code is Maps specific, not Earth.
I just want to build a drill down map like this - Drill Down Map
Here I want to show some data on tapping of each regions.I am out of clue. How can I ? What should I use ? From where to start ?
EDIT : In the link it's showing the country name on mouse over, instead of that I want to show some data/info of the country on touch. Please visit the map shown in the link,you'll get the whole idea.
Thanks !!
If you want total control on the map layout, and be able to check which country the users taps, there's no secret : you need to have boundaries of all countries you want to detect.
Here's the global approach I would use to reimplement something that looks like the map you linked to (I can you into more details if you want, but at first, here's the global approach) :
Get the data of the boundaries of the countries you need. This can be done using OpenStreetMap.org data.
[EDIT] I just came accross this website to download countries boundaries as files you can then use with tilemill : http://www.gadm.org/country
Use this data with tilemill (http://mapbox.com/tilemill/) : this tool is able to design maps using a language that looks like CSS but dedicated for maps. The results is great and the tool great as well. This tool also support shapes files, so if you can get the countries boundaries as shapefiles, you'll be able to use them with tilemill, and this will be easier than using .osm files from open street map). Have a look here http://mapbox.com/tilemill/data/ for the supported formats.
Then, with tilemill, export your map as an MBTile file (this file contains all tiles needed to get the map rendered at different zoom levels).
Use the route-me project to display the resulting MBTile file (in its latest version, route-me is able to do that, this feature has been implemented by the mapbox team to support their open format MBTile).
Guys from Mapbox have published a good tutorial "from data to maps" here : http://mapbox.com/demo/making_massredistrict/ this may help as well
Your best bet is to use CloudMade ( http://cloudmade.com/ ). They provide custom map builders program where you can build custom maps and can integrate those maps in your iOS app.
Depends what you are looking for. To implement the linked example it's enough with a giant image that you can split in tiles using CATiledLayer. You'll find examples if you google a little, PhotoScroller is one. If you want to display real maps you have to investigate the route me project.
I don't think that using images could be good option.Check this link - arcgis-iphone api. I am not so sure but you can get some idea from this.
Happy to help..
SO I am a totally new and do not know where to begin. I basically want to create a view that shows the users current location and directs them to my set location (park, concert, business, etc.). It seems fairly simple but there is so much smoke and mirrors online that I do not know where to start or how to finish. Would it be easier to call to google maps or use the mapview in the SDK?
And the bigger question is how do you do this? I mean I can create simple views and load webviews but I can not figure this out.
Use MKMapView .. its fairly straightforward to set up -- you can get the current location from CLLocationManager and pass its coordinates to the map view.

Have a look at this website http://www.martip.net/blog/localized-current-location-string-for-iphone-apps
it will help you with the current location thing.
Directions are part of the Maps application and are not available in the MapKit API. To give your users Google Maps directions, you need to use the Maps URL scheme, as documented in the Apple URL Scheme Reference. Specifically, you need to include the saddr and daddr parameters in the URL, which specify the start and destination addresses for a directions search, respectively. I believe you can pass latitude/longitude coordinate pairs (comma-separated) for those parameters, but you’ll have to experiment a bit to find the correct formatting and order.
By "direct" do you mean actually show a path for how to get there? That there is no API for. You can place a pin anywhere on a map to show people where something is, but they have to figure out how to get there themselves.
The term you are looking for to add points to a map is adding Annotations to an MKMapView.

how to download cloudmade map tiles? i have to download tiles with different zoom levels? how save these tiles to database for later loading? any sample code available? any help is appreciated..
There are different options available to you.
First, you can use the Javascript "Web Maps API". This is useful if you are wanting to show the maps on a website. It will download the required tiles and display them appropriately, and give you the interface to pan and zoom the map. See their pages at http://developers.cloudmade.com/projects/show/web-maps-api
Second option is if you want to access the map tiles directly. They call it their HTTP Maps API. You will need to make the calcuations of which tiles to download, how to arrange them etc for your own application. Have a look at http://developers.cloudmade.com/projects/show/tiles
Finally, although you don't mention it in your question, I see the question is tagged with "iphone" and other related things. Perhaps you want to look at their iPhone SDK, which is similar to the Web Maps API. See http://www.developers.cloudmade.com/wiki/iphone-sdk/Examples for examples on how to use it.
