need investigation, I get the error at compile time but not in Android studio

[mrbm]

I am on Studio 3.1.1 on a mac high sierra with:

Flutter 0.2.5 • channel unknown • unknown source Framework • revision bffae21571 (3 weeks ago) • 2018-03-28 12:07:12 -0700 Engine • revision dd6f46c485 Tools • Dart 2.0.0-dev.41.0.flutter-2f68e82526

And I get that same message.

[jparound30]

maybe about this line.

https://github.com/dart-flitter/flutter_webview_plugin/blob/c9033c4181a8564921703f8a7a69e2e6bb4c5889/android/src/main/java/com/flutter_webview_plugin/WebviewManager.java#L62

This API was deprecated at API level 21.
But if it is above API level 21, it is already implemented that uses another API.

I think, there is no problem.

@jparound30
so upgrade flutter_webview_plugin to new version?

[samgithub-duplicate]

I'm not quite sure what the solution to this problem is. I just upgraded to Flutter Preview Release 2 (which also installs DART 2) -- That's when the problem started:

I have the latest version of the plugin. (flutter_webview_plugin: ^0.2.1+2)
Flutter Doctor has no issues found. Should I just ignore the error?

I have the same problem,
but this happens only when you install the app, when it is already installed and you are only updating / developing ... this does not happen to me or when you run the flutter clean
