Can't run the custom analyzer_plugin in local project : "Unrecorded error while starting the plugin."

Question

I struggle at running a sample demo project and plugin for the analyzer_plugin

https://github.com/evaisse/dart_demo_analyzer_plugin

• I create sample demo project named "demo_analyzed_project" in (./example/demo_analyzer_plugin)
• Which use "demo_analyzer_plugin" (in ./)
• And the attached "demo_analyzer_plugin_loader" package in ./tools/analyzer_plugin

using dart : Dart SDK version: 2.19.6 (stable) (Tue Mar 28 13:41:04 2023 +0000) on "macos_x64"

Using Android studio, I got no analysis and I can't get rid of the following error from the analyzer diagnostics webpage :

Unrecorded error while starting the plugin.
#0      PluginSession.start (package:analysis_server/src/plugin/plugin_manager.dart:982:22)
#1      PluginInfo.start (package:analysis_server/src/plugin/plugin_manager.dart:219:21)
#2      PluginManager.addPluginToContextRoot (package:analysis_server/src/plugin/plugin_manager.dart:344:23)
