Running an app on flutter dev channel gives error "Could not find io.flutter:x86_release xxx "

Question

I am trying to run a flutter app on dev channel. Which gives the below error. But some other applications works fine. Is there any configuration needed for an existing app to work on dev channel, beside API compatibility. See the output of flutter doctor etc below. I tried running again after flutter clean but same result.

Edit: look like an android specific issue, as it build and run fine on IOS simulator! Edit 2: It also works from Android Studio, but not through vscode / command line (flutter run)

Answer 1

The mystery of why it work at Android Studio & IOS but not VSCode is due to that both uses different dart & flutter SDK, and packages/dependencies. This is because the editor plugin uses its own sdk and cache. So, configuring it all to point to same sdk solved the issue.
