[Bug] "Fix All" option does not work due to lack of bulk fix support in analysis_server_plugin

[maranix]

Issue Summary

The "Fix All" option provided by Dart Analyzer/LSP Server is currently non-operational. This is due to the analysis_server_plugin not supporting bulk fixes as referenced in the official documentation:

Writing Fixes: The ResolvedCorrectionProducer class

Additional Details

• In the documentation, under the explanation of CorrectApplicability, it is highlighted that bulk fix is not currently supported by the plugin system.
• This limitation means that users cannot apply a single "Fix All" action across a file or project when using plugins that rely on analysis_server_plugin.

References

• Dart SDK Writing Fixes Documentation

Potential Solution Path

• Investigate the feasibility or roadmap for adding bulk fix support to the plugin or wait for the official support to land in the plugin itself.
• Alternatively, document this limitation clearly in user-facing readmes and plugin documentation to manage expectations.
