Issue
In my flutter project, I have made some updates of plugins and then used flutter upgrade. After that, whenever I am running my flutter project it is showing following error-
/C:/src/flutter/flutter/.pub-cache/hosted/pub.dartlang.org/platform-3.0.2/lib/src/interface/local_platform.dart:46:19: Error: Member not found: 'packageRoot'.
io.Platform.packageRoot; // ignore: deprecated_member_use
^^^^^^^^^^^ FAILURE: Build failed with an exception.
* Where: Script 'C:\src\flutter\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 1102
* What went wrong: Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'C:\src\flutter\flutter\bin\flutter.bat'' finished with non-zero exit value 1
* Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

BUILD FAILED in 20s Exception: Gradle task assembleDebug failed with exit code 1
So, I need a suggestion that how can I solve this issue?
Solution
For me, cleaning and getting the packages didn’t work. This error started after I upgraded flutter. I was on the master channel, a quick fix for me was to switch to stable.
flutter channel stable
flutter upgrade
Perhaps theres a better solution which deals with platform package directly.
