Having the same problem after migration, pls help :D

@PrzemyslawPluszowy

@PrzemyslawPluszowy Can you provide us a runnable reproducible code sample in properly formatted text so that we can directly use it and verify at our end ? Providing code screenshot isn't much helpful.

another error after migration to flutter maps 2.6.1 in another project
when i'm back to .fromAssetImage all work fine

static Future<BitmapDescriptor> _createIcon(MapPinType type) async {
    return await BitmapDescriptor.asset(
      const ImageConfiguration(
        devicePixelRatio: 2.5,
        size: Size(28, 28),
      ),
      type.getPathIcon(),
    );
  }
}

enum MapPinType {
  accident,
  towing,
  delivery;

  String getPathIcon() {
    switch (this) {
      case MapPinType.accident:
        return Assets.images.iconMapCrashPng.path;
      case MapPinType.towing:
        return Assets.images.garageMapIcon.path;
      case MapPinType.delivery:
        return Assets.images.iconMapHome.path;
    }
  }
}

@PrzemyslawPluszowy

static generateCustomMarkersIconFromPath(String? path) async {

@PrzemyslawPluszowy How are you calling this method ? Can you provide us complete code (ex: main.dart) so that we can simply copy paste and verify this further ?

another error after migration to flutter maps 2.6.1 in another project

What version you were on earlier before upgrading to 2.6.1 ?
Also, this issue I was able to replicate with the help of another issue.

this is the same issue #149226 (comment)
Version 2.6.0, but I think the problem is with it when I upgraded Flutter to the newest version and ide show me deprecated

@jokerttu

This is an unintended effect of the way the federated change to add the new formats was rolled out. The new formats won't be supported until flutter/packages#6826 lands.

@jokerttu Could you do a new PR ASAP to remove the deprecation notice? We can re-add it after the implementation PRs have landed.

Same problem here, someone has any solution for this ?

The solution is not to use the new constructors until flutter/packages#6826 lands.

Ok, got it, thank you!!!

One thing I've noticed when using BitmapDescriptor.fromAssetImage() is that the marker sizing ends up being totally different on android Vs. iOS / chrome. So like everyone else has mentioned, using the other deprecated method return BitmapDescriptor.fromBytes(resizedData); Seems like the best solution currently.

It will be really awesome if BitmapDescriptor.asset() just works soon.

flutter/packages#6826 is now landed and new methods, BitmapDescriptor.asset() and BitmapDescriptor.bytes() are implemented for each platform, and can be used after using after plugin versions are updated to latest.
Latest version of google_maps_flutter 2.7.0 now also exposes new AssetMapBitmap and BytesMapBitmap classes.
See example to see how to use these new methods.
