flutter_test version conflict: version solving failed

[CarloRamponi]

Hello,
I'm new in flutter and i wanted to use flutter_map to display some maps in my new application.
I started with flutter_map 0.0.1 and there were no problems but once I've updated flutter I had an error (#12) that was solved in version 0.0.3 so I changed the version in my pubspec.yaml from

flutter_map: "^0.0.1"

to

flutter_map: "^0.0.3"

But when I try to run

flutter packages get

I get this error:

Running "flutter packages get" in pedibus_app...
Because every version of flutter_test from sdk depends on quiver 0.29.0+1 and flutter_map >=0.0.2
  depends on quiver ^0.28.0, flutter_test from sdk is incompatible with flutter_map >=0.0.2.
So, because pedibus_app depends on both flutter_map ^0.0.3 and flutter_test any from sdk, version
  solving failed.
pub get failed (1)

I have found no solutions...

Here is my pubspec.yaml if you need it:

name: pedibus_app
description: App for the pedibus project.

dependencies:
  http: "^0.11.3+16"
  flutter_map: "^0.0.3"
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.0

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - resources/logo.png
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies, 
  # see https://flutter.io/custom-fonts/#from-packages

Thanks in advance.

Meanwhile there is no fix for this, I recommend you to change the HEAD of the Flutter repository to the release before the upgrade of quiver version.

The preovious release to the updagre of quiver version in flutter repository is b397406561f5e7a9c94e28f58d9e49fca0dd58b7.

Hope it helps you @CarloRamponi

You change the quiver version to 0.29 like this as a workaround or just add this to your pubspec.yml:

  flutter_map:
    git:
      url:
        https://github.com/quangIO/flutter_map/
      path:
        flutter_map
      ref:
        dev

You can also set quiver to ^0.29.0 as a dependency_override:

dependency_overrides:
  quiver: ^0.29.0

Thank you very much for your answers!
Problem solved

And how did you solve it? @CarloRamponi

[johnpryan]

The latest version of flutter_map doesn't depend on quiver anymore https://github.com/apptreesoftware/flutter_map/pull/32

[CarloRamponi]

I don't know if it's still needed because i'm not into it anymore...
I resolved it by adding this in my pubspec:

dependency_overrides:
    quiver: ^0.29.0

Like johnpryan suggested.

[johnpryan]

You shouldn't need dependency overrides, Upgrading to flutter_map version 0.0.10 will make the problem go away
