[BUG] Map is shown only when I move it

[PollyGlot]

What is the bug?

I have already read a few of the issuses (ex. #1563 & #23) but anything could fix my problem.

I've got this problem with the latest version of the package 7.0.2. I have my markers shown but tiles are loaded only when I move the map. Even with the fix proposed here it doesn't work.

Here is my flutter doctor :

flutter doctor --verbose
[!] Flutter (Channel [user-branch], 3.22.3, on macOS 14.5 23F79 darwin-arm64, locale fr-FR)
    ! Flutter version 3.22.3 on channel [user-branch] at /Users/pollyglot/dev/flutter
      Currently on an unknown channel. Run `flutter channel` to switch to an official channel.
      If that doesn't fix the issue, reinstall Flutter by following instructions at
      https://flutter.dev/docs/get-started/install.
    ! Upstream repository unknown source is not a standard remote.
      Set environment variable "FLUTTER_GIT_URL" to unknown source to dismiss this error.

How can we reproduce it?

I have my markers shown but tiles are loaded only when I move the map.

Here is what I have :

FlutterMap(
        mapController: mapController,
        options: MapOptions(
          // France as focus by default
          initialCenter: const LatLng(46.71109, 1.7191036),
          interactionOptions: const InteractionOptions(
            flags: InteractiveFlag.all & ~InteractiveFlag.rotate,
          ),
          onMapReady: () => mapController
            ..fitCamera(
              CameraFit.bounds(
                bounds: LatLngBounds.fromPoints([
                  if (proposal?.params?.receiver.location?.coordinates != null)
                    LatLng(
                      proposal!.params!.receiver.location!.coordinates[1],
                      proposal!.params!.receiver.location!.coordinates[0],
                    ),
                  if (proposal?.params?.sender.location?.coordinates != null)
                    LatLng(
                      proposal!.params!.sender.location!.coordinates[1],
                      proposal!.params!.sender.location!.coordinates[0],
                    ),
                ]),
                padding: const EdgeInsets.all(36),
              ),
            )
            // Fix proposed in the thread
            ..move(
              mapController.camera.center,
              mapController.camera.zoom + 0.0001,

Reading this PR (#1691) I have replaced onMapReady parameter with initialCameraFit.

Even if it fixes my problem I would like to have a bit of explication here if you mind ! Thank you !
