this is my code when using leaflet it works and when using mapbox it give me blank page

[ibrierley]

Bit confused, haven't you just commented out the URL for the tiles & subdomain and included an interactive webpage that wouldn't work (I can't tell properly from where I am), but you would need to include a tile serving URL ?
What happens if you use the original URL and subdomain ?

[cetorres]

@Muhammad-saafan you have to use the correct URL on the urlTemplate like this:

layers: [
new TileLayerOptions(
urlTemplate: "https://api.mapbox.com/v4/{id}/{z}/{x}/{y}@2x.png?access_token={accessToken}",
additionalOptions: {
    'accessToken': '<your-key>',
    'id': 'mapbox.streets'
})]

[stafyniaksacha]

layers: [
  new TileLayerOptions(
    urlTemplate: "https://api.mapbox.com/styles/v1/{id}/tiles/512/{z}/{x}/{y}@2x?access_token={accessToken}",
    additionalOptions: {
      'accessToken': 'pk.eyJ1IjoibXVoYW1tYWQ5NCIsImEiOiJjanF3N3o2ZzUwb2R1NDJudzJnY3VkMXcxIn0.jo3ONUsCTUYRv7YAZrehlQ',
      'id': 'mapbox.mapbox-streets-v8',
    },
  ),

this will work well, i took time to find good uri which work with leaflet too
notice that i removed < & > from your token, it will work now

[johnpryan]

@stafyniaksacha thanks for helping out. @Muhammad-saafan did this fix your issue? It sounds like we need to add a better explanation for additionalOptions?

[thanooshan]

Same issue, any solutions?

[johnpryan]

@thanooshan is your url template correct?

[thanooshan]

layers: [ new TileLayerOptions( urlTemplate: "https://api.mapbox.com/styles/v1/thanooshan/{somekey}/wmts?access_token="{accessToken}", additionalOptions: { 'accessToken': '{accessToken}', 'id': 'mapbox.mapbox-streets-v8', }, ) ]

@johnpryan This is my layers code. Am I missing something?

[thanooshan]

@johnpryan @stafyniaksacha Map is working.

We have to use CARTO url. Previously I used WMTS url.

[ollyde]

For anyone else stuck I found a url that works

Here an example:

Replace my username acidhue and the key after it with your own.

https://api.mapbox.com/styles/v1/acidhue/cjvb13pgd12t01flpd97ub8dx/tiles/256/{z}/{x}/{y}@2x?access_token=$mapboxKey

[johnpryan]

thanks @OllyDixon!

[cosmotek]

Fixed by getting a url from Mapbox studio > Share button > Third party tab > CARTO option in dropdown with the following code:

          Container(
            width: 500,
            height: 500,
            child: FlutterMap(
              options: MapOptions(
                center: LatLng(51.5, -0.09),
                zoom: 13.0,
              ),
              layers: [
                TileLayerOptions(
                  urlTemplate: "https://api.mapbox.com/styles/v1/<username>/ck15ozlow33tj1cph5cpt2y79/tiles/256/{z}/{x}/{y}@2x?access_token=<token>",
                ),
                MarkerLayerOptions(
                  markers: [
                    Marker(
                      width: 80.0,
                      height: 80.0,
                      point: LatLng(51.5, -0.09),
                      builder: (ctx) =>
                      Container(
                        child: FlutterLogo(),
                      ),
                    ),
                  ],
                ),
              ],
            ),
          ),

There are a few parts here that I would really love to see reflected in the docs for this plugin. First off, I had to figure out to use a container to size things, secondly, the URL and how to get it...
