how to load WMTS map

In answer to your question, WMTS is the default one like used in the README.

If you're asking about WMS, you can check out the examples in the examples folder.

like this, I can not load it: http://t0.tianditu.gov.cn/img_w/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=img&STYLE=default&TILEMATRIXSET=w&FORMAT=tiles&TILEMATRIX={z}&TILEROW={x}&TILECOL={y}&tk=您的密钥

When I visit that URL, I get this response:

{"msg":"非法Key","resolve":"请到API控制台重新申请Key","code":1}

Looks like you need an API key?

I mean, does it support this format

child: FlutterMap( options: MapOptions( center: LatLng(30.547645, 104.069887), zoom: 1.0, crs: Epsg4326(), plugins: [ MePolylinePlugin(), ], onTap: _collectPoint, ), layers: [ TileLayerOptions( urlTemplate: 'http://t0.tianditu.gov.cn/img_w/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=img&STYLE=default&TILEMATRIXSET=w&FORMAT=tiles&TILEMATRIX={z}&TILEROW={x}&TILECOL={y}&tk=3ef974146950ea15a27a2eface83e2ca', subdomains: ['0', '1', '2', '3', '4', '5', '6', '7'], tileProvider: NonCachingNetworkTileProvider(), ), MePolylineLayerOptions(paintModel: paintModel), ], ),

I'm not sure, but I think it should be supported.

Do you get any errors when you use it?

type 'Null' is not a subtype of type 'List' in type cast

Can you post the full stack trace?

I find this https://github.com/alexandre-melard/leaflet.TileLayer.WMTS Add WMTS layering for leaflet. but it's for leaflet not flutter_map

[ibrierley]

it works for me if I try and grab a tile direct, eg http://t0.tianditu.gov.cn/img_w/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=img&STYLE=default&TILEMATRIXSET=w&FORMAT=tiles&TILEMATRIX=4&TILEROW=2&TILECOL=2&tk=3ef974146950ea15a27a2eface83e2ca

[JaffaKetchup]

Well I'm not sure about the null error because I can't see that line of code, but 403 Forbidden is from the server, so you'll need to somehow solve that to get the tile.

But, like @ibrierley, I can also get the tile direct.

I also had the same problem, because the type of tk is browser，but Flutter's request does not carry the characteristics of the browser, so we can solve it by using a server-side tk。

我也遇到了同样的问题，因为使用的 tk 类型是浏览器的，但是 Flutter 的请求并不会携带浏览器的特征，所以我们用服务端类型的 tk 就可以解决。

This remains an issue for me, using WMTS has some benefits over WMS for visualization purposes as the tiled WMTS is generally faster and acts as a tile cache in front of the WMS service.

Hi @pablojimpas. Can you clarify your issue, as I think this was resolved for @zjyhll?

Hi @pablojimpas. Can you clarify your issue, as I think this was resolved for @zjyhll?

I was expecting to use something like WMSTileLayerOptions but for WMTS that instead of using the GetMap request would use the GetTile request, but I realized now that the author of this issue was using a regular TileLayerOptions and that works well as far as I understand.

The only inconvenience it's that it isn't very discoverable that this package supports WMTS and that the urlTemplate can become really long because of having to pass all the WMTS options directly in the string.
