Flutter does not copy assets into iOS 14 simulator?

Question

Not sure what I am doing wrong. I specify my assets in pubspec.yml like so

assets:
  - assets/markers/station.png
  - assets/markers/other/
  - assets/markers/files/

and try loading it as a marker image with flutter map:

child: FlutterMap(
              options: MapOptions(
                center: const LatLng(32.8150, -117.2734), // Set initial map center
                zoom: 12.0, // Set initial zoom level
                maxZoom: 16
              ),
              children: [
                TileLayer(
                urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png'),      
                MarkerLayer(
                  markers: [
                    Marker(
                      point: const LatLng(32.8150, -117.2734),
                      builder: (ctx) => Image.asset('assets/markers/station.png'),
                      rotate: false,
                    ),
                  ],
                  rotate: false,
                )
              ],

            ),

but on iOS all I see is a red box at the location where the marker image should be. Using this path 'markers/station.png' works with the Chrome debugger. So the file exists at least for the web debugging.

More, I browsed to the app bundle in the simulator and the Documents folder is empty. Per documentation I understand this is where my markers should end up

path/to/app/bundle/Documents/assets/...

but Documents is empty. I see no errors during app build regarding path conflicts. Also, I did

$ flutter clean
$ flutter pub get

to rebuild the app bundle but still no assets copied? Can anyone please suggest what to do? Thank you!

Here's the code. You've mistakenly wrote marker instead of markers.

        Marker(
          point: const LatLng(32.8150, -117.2734),
          builder: (ctx) => Image.asset("assets/markers/station.png"),
          rotate: false,
        ),

Answer 2

My issue was that i had the asset directive outside of the flutter directive so assets were never copied.

Found it in another post. Needs to be

flutter:
  - assets:
    - assets/markers/station.png
