Widget name conflict with Flutter's View-widget

[jluukka-ge]

I've upgraded Flutter version from 3.3.10 to latest. Now I'm unable to use this library.

Flutter has introduced a new View-widget, whose name collides with the one defined in this library. The error originates from graphic-library's source.

I first encountered the problem when trying to build an APK of my app in an updated build environment. My app includes a simple line graph with minimal configuration. I would assume reproducing the problem should be as simple as trying to build any app which uses the graphic library with the latest version of Flutter. I'll try to verify this with a simple project in the near future.

Below is the error message produced by the failing build process.

It seems OK in my case, I upgraded to Flutter 3.7.3 stable.
And I did't find View Widget in latest Flutter documents.

IM having the same issue with flutter 3.8 in the master channel, can you provide a workaround??

[entronad]

I will check the 3.8
(Why your Flutter version so new? I suggest you to use stable channel for production)

Hey guys , My flutter is Channel master, 3.8.0-4.0.pre, I have similar issue and solved it temporary . It was change in the chart.dart code from

22 import 'view.dart to
22 import view.dart as v

189 View<D>? view;
189 v.View<D>? view;

748 state.view = View<D>(
748 state.view = v.View<D>(

after this operation everything okay till I rebuild my dependencies this problem back again . As I understand conflict between libraries of dart and packages . What to do with that ?

[entronad]

I have fiexed it in v2.0.2 by changing the View to ChartView.

Still I an curious why you use a master channel of Flutter instead of stable or beta, would you tell me your consideration?

That was the right solution tbh,

This was a bad call made earlier when we need it some fixes that were only live in master
