Stadia Maps is a popular tiered-payment (with free-tier) tile provider solution, especially for generic mapping applications. Setup with 'flutter_map' is relatively straightforward, but this page provides an example anyway.

Pre-made Styles

Stadia Maps offers a variety of map styles out of the box, that don't require customization.
For normal usage with raster tiles, use the Raster URL for the style you like, then follow the Normal (raster) instructions.
For more information about using the vector tiles, see Vector Usage.

Custom Styles

You can find details on Stadia Maps' support for custom styles at the bottom of the map styles documentation.

Usage

Normal (raster)

You should remove the 'api_key' (found at the end of the URL) from the URL for readability. Instead, pass it to additionalOptions.
FlutterMap(
options: MapOptions(
center: LatLng(51.5, -0.09),
zoom: 13.0,
),
nonRotatedChildren: [
AttributionWidget.defaultWidget(
source: 'Stadia Maps © OpenMapTiles © OpenStreetMap contributors',
onSourceTapped: () async {
// Requires 'url_launcher'
if (!await launchUrl(Uri.parse("https://stadiamaps.com/attribution"))) {
if (kDebugMode) print('Could not launch URL');
}
},
)
],
children: [
TileLayer(
urlTemplate: "https://tiles.stadiamaps.com/tiles/alidade_smooth_dark/{z}/{x}/{y}{r}.png?api_key={api_key}",
additionalOptions: {
"api_key": "<API-KEY>",
},
userAgentPackageName: 'com.example.app',
maxNativeZoom: 20,
),
],
);

Vector Usage

Stadia Maps' also provides vector tiles. For more information about using vector tiles, please see Using Vector Tiles.
However, please note that this method of integration is still experimental. Many of the Stadia Maps styles utilize advanced features of the Mapbox GL JSON style language which are not yet well-supported.
