Is an error due to the new dart version 2.0.0-dev ?
Thanks

[toregua]

I think it may be related to the new dart version

In order to have flutter packages get working i need to change your environnement requirement with sdk: '>=1.9.0 <=2.0.0-dev.16.0' in the pubspec.yaml but package uri: "^0.11.1" that map_view use seem to be not compatible with the new dart 2.0.0-dev.16.0 because flutter packages get fail because of him

[Samaritan1011001]

Can you show your pubspec.yaml ? Also have you tried this in the previous dart version?

[matthewtsmith]

@johnpryan Can you look at this. I think we dealt with a similar problem in another plugin.

and if i uncomment # map_view: "^0.0.10" error arrives when i use "flutter packages get".

Before i run "flutter upgrade" everything was ok with previous dart version

[johnpryan]

I was able to reproduce your issue - I fixed it by running flutter upgrade on the dev channel:

flutter channel dev
flutter upgrade

I can now run flutter packages get on your pubspec:

flutter packages get
Running "flutter packages get" in foo_test...         1.0s

[toregua]

Thank @johnpryan for helping me but even when i switch to channel dev i have error when map_view: "^0.0.10" is uncomment.

Error appear when flutter packages upgrade is executed and i have a classic pub upgrade failed (1)

If i comment map_view in my pubspec.yaml file everything is ok on channel dev.

EDIT : It is ok with channel MASTER for me ;)
Thank you
