After upgrading flutter to 1.12 and the cached_network_image to ^2.0.0-rc.1, flutter packages get returns version solving failed.

Running "flutter pub get" in gestor-mobile...                   
Because flutter_map 0.7.3 depends on cached_network_image ^1.1.0 and no versions of flutter_map match >0.7.3 <0.8.0, flutter_map ^0.7.3 requires cached_network_image ^1.1.0.

So, because gestor depends on both cached_network_image ^2.0.0-rc.1 and flutter_map ^0.7.3, version solving failed.
pub get failed (1; So, because gestor depends on both cached_network_image ^2.0.0-rc.1 and flutter_map ^0.7.3, version solving failed.)
exit code 1

Same issue. I had this before and handled with it somehow, don't remember.

I have same issue and for now this changes in 'pubspec.yaml' file work for me:

flutter_map: 
   git:
     url: git://github.com/okaxaki/flutter_map.git
     ref: fix/support-flutter-1.10

and

flutter_map_marker_cluster:
   git:
      url: git://github.com/emidiao/flutter_map_marker_cluster.git
      ref: e1b4ad9c6d300649acd448a9ba9069d865845686

This should be fixed in 0.8.0. See #480 for details.
