I’m not sure what this file does but seems very web related:

you can try and exclude generated_plugin_registrant.dart from analysis, this worked fine for me.

just add in project root a file named analysis_options.yaml with the following content:

analyzer:
  exclude: [lib/generated_plugin_registrant.dart]
