Because no versions of charts_flutter match >0.9.0 <0.10.0 and charts_flutter 0.9.0 depends on intl >=0.15.2 <0.17.0, charts_flutter ^0.9.0 requires intl >=0.15.2 <0.17.0.

Description

When I run flutter pub get, I got this.

Because no versions of charts_flutter match >0.9.0 <0.10.0 and charts_flutter 0.9.0 depends on intl >=0.15.2 <0.17.0, charts_flutter ^0.9.0 requires intl >=0.15.2 <0.17.0.
And because every version of flutter_localizations from sdk depends on intl 0.17.0-nullsafety.2, charts_flutter ^0.9.0 is incompatible with flutter_localizations from sdk.
So, because bee_bdapp depends on both flutter_localizations any from sdk and charts_flutter ^0.9.0, version solving failed.
pub get failed (1; So, because bee_bdapp depends on both flutter_localizations any from sdk and charts_flutter ^0.9.0, version solving failed.)

make the following changes to the app’s pubspec.yaml file:

dependency_overrides:
 intl: '>=0.15.2 <= 0.17.0-nullsafety.2'

[elansys-kc]

I get

Warning: You are using these overridden dependencies:
! intl 0.16.1

I still get a build failure

I found the following enabled the build to continue. I kept it as an override to show a warning during pub get.

dependency_overrides:
  intl: '>=0.17.0-nullsafety.2 <= 0.17.0-nullsafety.2'

I haven't tried this yet, but I think it is a hark way.
I think a better approach would be for Charts to release an update for its dependent versions.

[ghenry]

Please release an update :-)

[LAPPIT]

Get the same problem as well:

Because charts_flutter 0.9.0 depends on intl >=0.15.2 <0.17.0 and no versions of charts_flutter match >0.9.0 <0.10.0, charts_flutter ^0.9.0 requires intl >=0.15.2 <0.17.0.
So, because minsockerbit depends on both charts_flutter ^0.9.0 and intl ^0.17.0, version solving failed.
pub get failed (1; So, because minsockerbit depends on both charts_flutter ^0.9.0 and intl ^0.17.0, version solving failed.)

Please release an update! Really hope to be able to continue using the package ...

[hdavidmb]

Facing same issue. I tried downgrading intl to intl: ^0.16.0, but as my app also depends on flutter_localizations it needs intl: ^0.17.0 so I cannot run my app.
I also hope charts gets updated to continue using the package.
