should not update until flutter sdk master branch is on this version too.
(Flutter sok has a fixed version of 0.15.8 atm)

[Pavel-Hrdy]

Please merge, Flutter SDK now uses this updated version.

[Gerrel]

Yes Flutter sdk is now updated for 0.16.0, but not all libraries are updated so I propose a broader pubspec constraint like '>=0.15.8 <=0.16.0' if possible.

We are facing the same issue in our project, please update as soon as you can on 0.16.0, if it is possible? @fadhly-permata

Any updates on this getting merged?

[marcosnataqs]

Why not merged yet? @fadhly-permata help us!

[m-sadegh-sh]

At this time it's impossible to use this package with latest version of Flutter. Is there any workaround to overcome this issue?

[10ndavis]

@fadhly-permata Can we please get this reviewed, or have another developer given access to help approve PR's? This is a very simple change but is blocking us from using your plugin.

If you are using the newest version of intl package you can override this packages intl dependency in your pubspec.yaml file.

dependency_overrides:
  intl: ^0.16.1
